The purpose of the research presented in this article is to analyse landslide hazards by assessing the impact of the natural component of factors on land use within the Kosiv district of the Ivano-Frankivsk region. The increasing number of negative consequences of landslide processes in the study area, and especially in the Carpathian region of Ukraine, requires the creation of new approaches to land resource assessment and civil engineering to reduce the negative impact of landslides on the environment and human activities. Methods. Landslide processes were studied using geophysical methods, GPS and geostatistical methods of data analysis. Based on the created mapping layer of the land cadastre and the landslide hazard map for Kosiv district, a vector analysis was performed to assess the risk in each area according to its cadastral number. Results. The environmental and geological risk of the natural component of landslide hazard factors was calculated using geoinformatics and geostatistical analysis tools with the use of QGIS. An important result of the research is the creation of landslide risk maps of land plots based on data from the State Land Cadastre using the Kadastr.Live Toolbar plugin. Scientific novelty. For the first time an analysis of the natural component of landslide hazard risks for the territory of Kosiv district was carried out as a basis for the assessment of such risks for individual cadastral zones. The regulatory and monetary assessments were clarified based on individual territories, for conducting economic activities that require hydrogeological research or changing the intended use of land.. Practical significance. By applying the methodology of dividing landslide risk assessment factors into natural and anthropogenic components, it becomes possible to identify areas within the study area with the highest probability of landslide development and activation. This method helps to study the characteristics of natural factors and is useful in assessing the risk of landslides..

Full textAbstract:
This article is focused on the use of photography to characterize land-cover and land-use changes in a 7.59 km2 study area centered on Hotel do Garbe, in the village of Armação de Pêra, Algarve, Portugal. Orthorectified vertical aerial, oblique aerial and ground-level photographs were the main data sources required to carry out the analysis. In a preliminary approach, a conventional research design was adopted. Based on the available orthorectified vertical aerial photographs, a sixty-year time series, with four homogeneously distributed steps (1958, 1978, 1997 and 2018), was constructed, and maps were produced to support the description of the changes that have taken place. To deepen the analysis, photographs from fourteen picture postcards were recognized as a useful source of information, and the authors of these photographs were considered “involuntary or accidental photo-geographers” whose work was relevant to feed a case study in which human geography and landscape biography sciences are the main narrative axes. The final result proved to be richer than the interpretation only based on the orthorectified vertical aerial photographs, and the importance of combining photographs taken from different points of view, with different aims and for different recipients is highlighted.

The article explores some aspects of the use of unmanned aerial vehicles (UAVs), approaches to their classification and possible areas of application. The main advantages and disadvantages of using unmanned aerial vehicles of different types (quadcopter and aircraft type) in comparison with classical aerial photography and ground shooting are revealed. The features of UAV aerial photography at different stages of semi-automatic mode are considered. Aerial photography of a local object (land with vegetation and the building of the NULES of Ukraine building) was performed by a quadcopter with the subsequent acquisition of an orthophoto, a digital model, construction of a 3D image and a further topographic plan of scale 1:500. Surveying materials were proceeded with a specialized Pix4D program. We counted the time needed to perform separate stages of material processing. In this case, all stages of processing were performed in automatic mode, except for entering coordinates of anchor points. The main disadvantage of this program was the need to form a 3D model in manual mode without the possibility of phased saving. The article offers a classification of the main problems of using UAVs, namely: regulatory, technical and scientific. The comparative assessment of the use of technologies of tacheometric survey, terrestrial scanning, lidar and aerial photography with UAV and their use for land cover monitoring purposes was made.

Abstract Color aerial photography was used to assess crown color classes in loblolly pine (Pinus taeda L.) plantations. Three distinct Munsell color classes were delineated on the resulting photographs. Foliar N levels and, to a lesser degree, foliar K levels were directly related to color. Significant relationships between color and site index and color and basal area were shown. Application of color aerial photography, combined with Munsell color coding, could expedite land classification and also make possible more efficient use of fertilizers. South J. Appl.

The aims of our paper are to study the territory organization of the forest fund lands of the Skhidnytsya village council (Lviv region), performing their forest management with the development of a system of activities aimed at ensuring scientifically based multifunctional forestry management, protection and rational sustainable use. The possibility of performing cadastral works for the territorial organization of forestry lands using unmanned aerial vehicles (UAVs) is important for science and practice. The paper considers the main direction of sustainable development of forest areas with a recreational function, aimed at strengthening ecological, social and economic functions and protection of these forests, their rational use. Based on the division of forests into categories, their functional significance, the regime of forestry and forest use for the next revision period, the following economic units were formed: health and recreational forests with a special regime of use in the mountains. The distribution of the total area of health and recreational forests by functional zones, types of landscape, classes of aesthetic assessment, pedestrian accessibility, recreational assessment, resistance to recreational loads, stages of recreational digression, additional assessment is presented. The results obtained prove the practical significance of the use of UAVs for performing work on the organization of the territory (certain category of land), and the resulting cartographic materials fully comply with the instructive accuracy. The developed provisions of this study correspond to the basic principles of sustainable forest management, provide for a combination of economic, environmental and social aspects of forestry activities.

<p><strong>Abstract.</strong> Libraries, museums and archives were the original big geospatial information repositories that to this day house thousands to millions of resources containing research-quality geographic information. However, these print resources (and their digital surrogates), are not easily incorporated into the contemporary research process because they are not structured data that is required of web-mapping and geographic information system tools. Fortunately, contemporary big data tools and methods can help with the large-scale conversion of historic resources into structured datasets for mapping and spatial analysis.</p><p>Single frame historic aerial photographs captured originally on film (hereafter “photographs”), are some of the most ubiquitous and information-rich geographic information resources housed in libraries, museums and archives. Photographs authentically encoded information about past places and time-periods without the thematic focus and cartographic generalization of historic print maps. As such, they contain important information in nearly every category of base mapping (i.e. transportation networks, populated places etc.), that is useful to a broad spectrum of research projects and other applications. Photographs are also some of the most frustrating historic resources to use due to their very large map-scale (i.e. small geographic area), lack of reference information and often unknown metadata (i.e. index map, flight altitude, direction etc.).</p><p>The capture of aerial photographs in the contiguous United States (U.S.) became common in the 1920s and was formalized in government programs to systematically photograph the nation at regular time intervals beginning in the 1930s. Many of these photography programs continued until the 1990s meaning that there are approximately 70 years of “data” available for the U.S. that is currently underutilized due to inaccessibility and the challenges of converting photographs to structured data. Large collections of photographs include government (e.g. the U.S. Department of Agriculture Aerial Photography Field Office “The Vault” – over 10 million photographs), educational (e.g. the University of California Santa Barbara Library – approximately 2.5 million photographs), and an unknown number non-governmental organizations (e.g. numerous regional planning commissions and watershed conservation groups). Collectively these photography resources constitute an untapped big geospatial data resource.</p><p>U.S. government photography programs such as the National Agricultural Imagery Program continued and expanded in the digital age (i.e. post early 2000s), so that not only is there opportunity to extend spatial analyses back in time, but also to create seamless datasets that integrate with current and expected future government aerial photography campaigns. What is more, satellite imagery sensors have improved to the point that there is now overlap between satellite imagery and aerial photography in terms of many of their technical specifications (i.e. spatial resolution etc.). The remote capture of land surface imagery is expanding rapidly and with it are new opportunities to explore long-term land-change analyses that require historical datasets.</p><p>Manual methods to process photographs are well-known, but are too labour intensive to apply to entire photography collections. Academic research on methods to increase the discoverability of photographs and convert them to geospatial data at large-scale has to date been limited (although see the work of W. Karel et al.). This presentation details a semi-automated workflow to process historic aerial photographs from U.S. government sources and compares the workflow and results to existing methods and datasets. In a pilot test area of 94 photographs in the U.S. state of Pennsylvania, the workflow was found to be nearly 100-times more efficient than commonly employed alternatives while achieving greater horizontal positional accuracy. Results compared favourably to contemporary digital aerial photography data products, suggesting that they are well-suited for integration with contemporary datasets. Finally, initial results of the workflow were incorporated into several existing online discovery and sharing platforms that will be highlighted in this presentation. Early online usage statistics as well as direct interaction with users demonstrates the broad interest and high-impact of photographs and their derived products (i.e. structured geospatial data).</p>

The Land Code of the Russian Federation provides for payment for any use of land. The exception is cases established by federal laws and laws of the constituent entities of the Russian Federation. The inventory works on land and land plots in the Novosibirsk city were not carried out during the period of its modern history. As part of the adopted inventory program for VAT and on the basis of the municipal contract SSUGiT in the period from 2018 to 2022 performed a set of works to clarify (determine) the location and characteristics of lands and land plots located within the boundaries of the city of Novosibirsk. The article discusses the individual stages of the completed set of works under the Program, which provide for experimental studies to assess the possibilities of determining the boundaries of land plots and identifying violations. The studies were carried out using aerial photography ma-terials obtained by using unmanned aerial vehicles. As a result of the research, it was concluded that orthophotomaps obtained from UAV aerial photography make it possible to identify violations with minimal complexity and cost by comparing the actual and “accounting” boundaries.

Historical aerial photography has become a valuable commodity in any country, as it provides a precise record of historical land management over time. In a developing country, such as South Africa, that has undergone enormous political and social change over the last years, such photography is invaluable as it provides a clear indication of past injustices and serves as an aid to addressing post-apartheid issues such as land reform and land redistribution. National mapping organisations throughout the world have vast repositories of such historical aerial photography. In order to effectively use these datasets in today’s digital environment requires that it be georeferenced to an accuracy that is suitable for the intended purpose. Using image-to-image georeferencing techniques, this research sought to determine the accuracies achievable for ortho-rectifying large volumes of historical aerial imagery, against the national standard for ortho-rectification in South Africa, using two different types of scanning equipment. The research conducted four tests using aerial photography from different time epochs over a period of sixty years, where the ortho-rectification matched each test to an already ortho-rectified mosaic of a developed area of mixed land use. The results of each test were assessed in terms of visual accuracy, spatial accuracy and conformance to the national standard for ortho-rectification in South Africa. The results showed a decrease in the overall accuracy of the image as the epoch range between the historical image and the reference image increased. Recommendations on the applications possible given the different epoch ranges and scanning equipment used are provided.

The use of unmanned aerial vehicles (hereinafter referred to as “UAV”) is one of the most popular ways of collecting objective spatial data on the land plots under survey. The main advantages of UAVs include the significantly lower cost of surveying, design and complex cadastral works compared to traditional methods of determining coordinates (e.g. performing a tacheometric survey and plane-table survey). The designed sector of block No. 9 in the Yurga urban district of Kemerovo region with cadastral No. 42:36:0102001 (land category: residential), comprising 22 apartment buildings, is taken as an example. The economic performance of land plots marking, carried out with cadastral accuracy, based on data obtained using UAVs and without the use thereof, is assessed.

The development of exogenous processes on the Earth's surface is a large-scale problem. Due to the development of exogenous processes there are changes in the composition and structure of the earth's crust and its surface. The destruction of streets, houses and public buildings, roads and railways leads to enormous losses. To predict the development of soil degradation, erosion processes on agricultural lands, which lose annual production areas, leads to the formation of a ravine-beam system and reduces the productive amount of land owned by citizens – is a solution. The use of GIS technologies, remote sensing of the Earth and modern programming can partially solve the problem, as it is a rapid identification of areas that have undergone the process of soil degradation and possible prediction of the development of negative phenomena. The use of geodetic software, GIS, information layers of the Public cadastral map can help in the fastest finding of territories, development of the forecast of the further destructive action, development of the corresponding protective methods and their introduction. The areas with manifestations of exogenous processes - soil degradation in agricultural enterprises, where every year the area of highly fertile chernozems is lost, which leads to large losses and landslides in the forest-steppe and steppe settlements of Kharkiv region have been subject of our study. We investigated destructive processes by geodetic measurements in the territories of their manifestations, observations were carried out for 8 years. The development of exogenous processes on the Earth's surface was revealed, which was manifested in landslides in the settlements of the forest-steppe zone and degradation of agricultural lands in the steppe and forest-steppe part of Kharkiv region. The cause of the destruction of the earth's surface were factors independent of human activity. We built 3-D models of development of exogenous processes manifested in soil erosion and growth of the ravine-beam system and determined the degree of erosion after surveying and processing the results of geodetic measurements in the software Digitals. For 8 years, we made changes to the software, surveying the area and building a monitoring line. Also in the settlements on the territory of the two zones, we observed the development of landslides on the streets of the village. Milova and s. Nova Vasylivka, where there is an intensive development of exogenous processes. The use of GIS technologies and remote sensing of the Earth to monitor the development of exogenous processes simplifies the solution.

Reforming the economy of our country, and in particular agricultural production, led to the inevitable reorganization of the territory. To carry out work on the reorganization, land management authorities need fresh cartographic materials. The emerging land cadastral service needs to perform a large amount of work on the inventory of agricultural land with the determination of their condition and use. Similar problems are faced by services involved in the inventory of urban lands and objects, the creation of a cadaster of built-up areas. The wide use of aerial photography materials is of great importance in solving these problems.

It has been proven that the transformational processes taking place in Ukraine are related to the deepening of crisis phenomena in the economic sphere, the slowdown of the main indicators of regional development, the impact of the consequences of the COVID-19 pandemic, and military operations. In such conditions, it is necessary to rethink approaches to ensure the efficiency of the functioning of regions by improving the system of land resources management, as the main factors of their development. At the same time, the modern European experience of land administration and information provision of the formation and use of real estate based on the application of the multi-purpose cadastre is considered. The aim of this work – to develop scientifically based recommendations for the formation of a multi-purpose cadastre at the regional level. To achieve the goal, the following tasks were completed: determination of the multi-purpose cadastre at the regional level; identification of factors affecting the formation of a multi-purpose cadastre; presentation of the results of mathematical modelling of the factors of formation of the multi-purpose cadastre; the formation of geo-information support of a multi-purpose cadastre. Method. To obtain research results, special methods are used: structural and content analysis - to form a conceptual apparatus for defining a multi-purpose cadastre at the regional level; analytical and methods of expert analysis - to determine the spatial, urban planning, investment and environmental factors of the information support of the multi-purpose cadastre; analysis of hierarchies - to determine the weighting factors characterizing the mutual influence of indicators of information provision of the multi-purpose cadastre; mathematical modelling - for the development of models that determine the impact of spatial, urban planning, investment and environmental factors on the integral indicator of information provision of the multi-purpose cadastre; correlation-regression analysis - to establish the influence of the integral indicator of information provision of the multi-purpose cadastre at the regional level on the gross regional product; of geo-information analysis - for the development of geo-information support of the multi-purpose cadastre. Scientific novelty and practical significance. An integral indicator for assessing the level of information provision of the multi-purpose cadastre is proposed, which is determined based on spatial, urban planning, investment and environmental factors, which allows forming the information basis for the development of scientifically based recommendations for the creation and implementation of the multi-purpose cadastre at the regional level. The concept of "multi-purpose cadastre at the regional level" was defined, which considers the totality of spatial, urban planning, investment and environmental support, which allowed to build a multi-level information system for the formation of a quantitative basis of real estate management at the regional level. The method of integral assessment of the level of information support of the multi-purpose cadastre at the regional level is characterized, which is based on a multi-level system of factors, methods of assessment of analytical and qualitative indicators, analysis of hierarchies, local, generalizing and integral models, which made it possible to carry out mathematical modelling of these factors, to form geo-information support for adoption reasoned decisions in the field of real estate management. The results of mathematical modelling of the processes of development of information support of a multi-purpose cadastre based on the establishment of relationships between system factors and an integral indicator by applying the method of correlation-regression analysis are presented, which makes it possible to build predictive models and establish trends in the formation and use of real estate at the regional level, taking into account the spatial, urban planning, investment and environmental support. Scientifically based recommendations for the development and implementation of a multi-purpose cadastre were proposed based on the results of their level assessment and modelling, which made it possible to single out directions for increasing the level of information provision and application of the multi-purpose cadastre for increasing the efficiency of real estate use at the regional level [Ноlovachov et al., 2022; Ноlovachov, 2022].

AbstractGiant reed is an invasive weed throughout the southern half of the United States, with the densest stands growing along the coastal rivers of southern California and the Rio Grande in Texas. The objective of this study was to use aerial photography to map giant reed infestations and to estimate infested areas along the Texas–Mexico portion of the Rio Grande. Aerial color-infrared photographs were taken along the Rio Grande between Brownsville and El Paso, TX, in June and July 2002. Based on the aerial photographs and ground surveys, the portion of the river from San Ygnacio to Lajitas, which has a river length of 898 km (558 mi), was found to be infested with giant reed. To estimate infested areas along both sides of the river, 65 (13.5%) of the 480 aerial photographs taken between Lajitas and San Ygnacio were randomly selected. The aerial photographs were digitized, rectified to Google Earth imagery, and then classified using maximum-likelihood classification techniques. The infested areas on both sides of the river, as well as water area and river length, from each photographic image were determined. Based on the estimates from the 65 aerial photos, the ratio of giant reed area to water area and the ratio of giant reed area to river length were calculated. The total giant reed area along the Rio Grande between Lajitas and San Ygnacio was estimated to be 5,981 ha (14,779 ac) with 3,714 ha or 62% on the U.S. side and 2,267 ha or 38% on the Mexican side. This study provides the first accurate estimates of giant reed infestations along the Texas–Mexico portion of the Rio Grande and will be useful for both land owners and government agencies for the estimation of water usage and economic loss and for the management and control of giant reed.

Purpose The purpose of this paper is to describe the procedure for near-automation of the most commonly used manual georeferencing technique in a desktop GIS environment for historic aerial photographs strip in library archives. Design/methodology/approach Most of the archived historic aerial photography consists of series of aerial photographs that overlap to some extent, as the optimal overlap ratio is known as 60 percent by photogrammetric standard. Therefore, conjugate points can be detected for the overlapping area. The first image was georeferenced manually by six-parameter affine transformation using 2013 National Agriculture Imagery Program images as ground truths. Then, conjugate points were detected in the first and second images using Speeded Up Robust Features and Random Sample Consensus. The ground space coordinates of conjugate points were estimated using the first image’s six parameters. Then the second image’s six parameters were calculated using conjugate points’ ground space coordinates and pixel coordinates in the second image. This procedure was repeated until the last image was georeferenced. However, error accumulated as the number of photographs increased. Therefore, another six-parameter affine transformation was implemented using control points in the first, middle, and last images. Finally, the images were warped using open source GIS tools. Findings The result shows that historic aerial strip collections can be georeferenced with far less time and labor using the technique proposed compared with the traditional manual georeferencing technique in a desktop GIS environment. Research limitations/implications The suggested approach will promote the usage of historic aerial photographs for various scientific purposes including land use and land cover change detection, soil erosion pattern recognition, agricultural practices change analysis, environmental improvement assessment, and natural habitat change detection. Practical implications Most commonly used georeferencing procedures for historic aerial photographs in academic libraries require significant time and effort for manual measurement of conjugate points in the object images and the ground truth images. By maximizing the automation of georeferencing procedures, the suggested approach will save significant time and effort of library workforce. Social implications With the suggested approach, large numbers of historic aerial photographs can be rapidly georeferenced. This will allow libraries to provide more geospatial data to scientific communities. Originality/value This is a unique approach to rapid georeferencing of historic aerial photograph strips.

The emergence of satellite observations was marked by their widespread use to determine the velocities and direction of horizontal motions of lithosphere plates (modern kinematics of lithosphere plates), which allowed to research the deformation processes at the global and regional levels. Today, permanent GNSS stations cover a large part of the land area. Since many of these stations have accumulated a large amount of daily observation over 20 years, it is possible to trace the deformation processes of certain areas. There is the problem of correct identification of observations of the true parameters of the deformation process. This issue requires the joint work of geophysicists and geodesists. But high-precision time series and values of GNSS station velocities are important and perspective data for the interpretation of geodynamic processes, which are much easier to obtain than geophysical or geological data, do not require special costs and should take into account their active development, the number of such stations is growing rapidly. Today, according to unofficial data, more than 300 reference stations operate in Ukraine. The aim of this work is to detect deformations of the Earth's crust in the Carpathian folded system using GNSS technology. The input data for the research were the observations over eight years (2013-2020) at reference stations in Ukraine (ZAKPOS network). From these observations, the combined solution (coordinates time series and velocities) was calculated using the scientific software GAMIT / GLOBK. According to the obtained data, the horizontal displacements vectors of GNSS stations were also constructed, and the deformations of the Earth's crust were calculated by the method of triangles, the vertices of which are GNSS stations, using the GPS Triangle Strain Calculator software. The calculated values of deformations showed a different geodynamic value, depending on the location of the triangles. In particular, the active zones of stretching (Rakhiv-Verkhovyna and Syanok-Ustryky-Dolishni) and compression (Rakhiv-Khust-Mukachevo) were identified. The research results make it possible to establish the features of the spatial distribution of crustal movement in the Carpathian region and in the future in a joint interpretation with geophysical data to create a regional geodynamic model of the Carpathian folded system.

Now all over the world there is a shift in the learning paradigm towards increasingly modern learning, the problems faced in Indonesia are very different from those in other countries. The need to accelerate spatial planning is increasingly needed day by day, but the lack of use of high resolution satellite imagery (CSRT) is very minimal because many still prefer to use aerial photography, even though satellite imagery has now developed rapidly and has an accuracy of 0.5 meters/centi, to obtain The data that I will use, I use the Mendeley software platform, and also search for several scientific journals from existing websites. The results that I got from the research study that I wrote as stated above is the importance of maximizing the use and utilization of images. This scientific study can conclude that the use of satellite imagery is no less important than aerial photography which requires more time in the field, the use of satellite imagery is a way to obtain information about the earth's surface from a certain distance. The concept is simple: if you observe a landscape object but it is still unclear, change perspective by standing up to see the object more clearly.

Field inspections of land plots for compliance with the requirements of land legislation by their owners or users imply a visual inspection and instrumental inspection of such real estate objects. However, when implementing these procedures, the following problems may occur: limited access to land plots through their fencing; a large area of land; the impossibility of obtaining the land plots boundaries coordinates using GNSS equipment, associated with the level of territory development or with the location near the survey area of objects that block or distort satellite signals. The study describes the expe-rience of using unmanned aerial vehicles in conjunction with digital cameras as a possible solution to the above problems. The purpose of the work is to describe the experience of using unmanned aerial vehicles to collect information on the actual use of land plots and the location of their boundaries in the framework of state land supervision. The paper describes the procedure for coordinating flights and the experience of using a quadcopter-type aircraft for aerial photography when surveying land. Options for the interaction of state land supervision bodies with other organizations and divisions of Rosreestr are presented for the purpose of assessing compliance with the land legislation of the Rus-sian Federation by owners and users of land plots, as well as filling the state fund with data obtained as a result of land management. The positive aspects of using such tools are given, as well as criticism of the existing work procedure. As a result of the research, it was concluded that the use of unmanned aerial vehicles shows high efficiency in the implementation of the functions of state land supervision, but it is necessary to further improve this area.

The aim of the work is to propose a method of creating a geographic information online resource for the management of Lisovohrynivetska UTC. To implement the tasks, a technological scheme was proposed, which consisted of 9 stages of work. The first stage involved the collection and analysis of disparate data in both vector and raster formats on the territory of the Lisovohrenivetska united territorial community. In the second stage, with the help of Global Mapper software, all vector data files in *.dxf and *.dmf formats, which were previously available, were converted to *.shp format for further processing in ArcGIS software. As a result of the conversion, graphic and attributive data were obtained in the required format and according to the layers they contain, the geodatabase with symbols according to the classifier was edited to create 1: 2000 scale plans. The next step was to unify the database of convertible files, as vector data was created with different construction of attribute tables. In addition, there is a need to enter vector data into the edited geospatial database. To do this, a ArcPy script was written that rearranges attribute tables and enters data into a geodatabase. Adjusted and populated the attribute database of vector objects for those columns where there was no information. The penultimate step was to develop the structure of the geoportal on the basis of ArcGIS-online to download the geodatabase to Lisovohrynivetska UTC on the server, to enable their external use with a unique login and password. The last step, after creating the structure of the geoportal, was to upload vector and raster geodata prepared by ArcGIS to the geoportal. As a result of the realization of the set purpose the technique of creating the geoinformation online resource for the management of the united territorial community is offered and described. During the implementation of the method the data of 24 disparate vector layers for the Lisogrynivtska community of Khmelnytsky region were processed and converted. Raster cartographic materials for UTC were collected and processed. The geodatabase according to the classifier for scale 1: 2000 is created. The structure of the geoportal based on the ArcGIS-online kernel with a connected map-base based on the online resource GoogleMaps, where all processed materials are downloaded, has been developed. The scientific novelty is to develop the concept of accumulation of heterogeneous vector and raster geospatial data in one geodatabase, by converting them into a specific format. Additional modules have been written in ArcPy to unify the database structure. Implemented geoinformation system is located on the geoportal and is designed for management decisions of community leaders. In addition, the created GIS can be used for land management and surveying work on community sites.

AbstractArchival aerial photographs obtained in the 20th century play a special role in the process of upgrading the register of land and buildings. These photographs are the only resource presenting credible information on the coverage and use of land in a high degree of detail. In this article, particular attention is paid to the aspect of the spectral resolution of archival aerial photographs. Preliminary research was conducted into the assessment of the impact of simulations of new spectral bands with high spatial resolution for archival photographs upon the interpretation process of such data. The proposed simulation method of new bands is based on the integration of archival monochromatic aerial images with archival multispectral satellite imagery. Visual and quantitative comparative analysis of monochromatic imagery and of enhanced images obtained by application of the simulation process was performed. The results of this research unanimously confirmed the improved interpretation possibilities of archival aerial photographs, associated not only with the assignment of colours but also with the reconstruction of spectral information for the arable and afforested land photographed.

There is no reliable information till now on the conversion rate of agricultural land in Bangladesh into different non agricultural sectors. The study was undertaken to estimate the present land use pattern and to calculate the changes in land use of agricultural and non-agricultural field over time using aerial photographs of Trishal and Fulbaria upazila of Mymensingh district. Two series of aerial photographs of both upazilas from 1983 and 2000 at scales of 1:40,000 and 1:25,000, respectively, were studied. Land use categories were calculated by random line drawing method on effective areas of aerial photograph. In 1983, Total agricultural and non-agricultural land of Trishal upazila were found 29,505 and 4,095 ha accounting 87.81 and 12.2% of total land area, respectively. In Fulbaria upazila for the same year, it was 35,611 and 4,258 ha accounting 89.3% and 10.7% of total land area, respectively,. An amount of about 3545 and 3637 ha agricultural land was transformed into non-agricultural land in Trishal and Fulbaria upazila, respectively, within a period of 17 years. The rate of decreasing agricultural land to non agricultural land in Trishal and Fulbaria upazila was estimated to be 0.62 and 0.54% /annum, respectively. Land use analysis shows that conversion of agricultural land into settlement, transport network and water body contributed 88.07, 5.3 and 6.63% of the land loss, respectively in Trishal upazila and 98.45, 1.3 and 0.12% of the land loss, respectively in Fulbaria upazila. If similar trends in loss of agricultural land remain constant, there will be no land available for cultivation after around 200 years. Therefore, it is very crying need for the country to make a land use policy for food security of the rapidly growing population. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21210 J. Bangladesh Agril.

Full textAbstract:
The article is devoted to the topical issue of geodetic planning in agro-landscape and its importance for efficient land use. The authors review modern methods and technologies for creating digital maps and models of agricultural landscapes based on the use of geographic information systems and aerial photography from unmanned aerial vehicles. Modern new approaches to geodetic planning within agrolandscapes are investigated. The requirements of the agricultural sector for digital mapping and modeling for the optimal use of land resources are determined. The tools for the formation of digital maps of agro-territories of united territorial communities are substantiated. Proposals for the use of geodetic methods for effective agro-landscape planning are formulated. The main attention is paid to the practical significance of the data obtained for optimizing land use, planning agricultural operations and rational use of land resources. The studied approaches and developments can be useful for farmers, landowners, ecologists and specialists in the field of geodesy. In the course of the study, a methodology and procedure for mapping agricultural landscapes using GIS and aerial survey materials using UAVs were developed. This methodology made it possible to obtain high-quality images of agricultural landscapes and develop a cartographic model in GIS based on them. The approach was successfully tested on the example of the selected model area near the ATC. The created digital map and database are promising for further research of agricultural landscapes. The research clearly shows that the data obtained as a result of UAV surveys is a high-quality source of reliable information. Aerial photography allows you to quickly create an accurate digital terrain model, which can serve as the basis for geographic information systems in the development of a number of thematic maps and terrain models important for the agricultural sector. The geographic information system makes it possible to visualize the main elements of agricultural landscapes as separate layers (e.g., relief, soil-forming rocks) with appropriate detailing of their characteristics in attribute tables. By combining different data sources, GIS allows you to create detailed maps of the agro-ecological conditions of a particular area. GIS can also be used to store information on field work, yields and other indicators, which ensures the rational management of agricultural processes on land plots.

Full textAbstract:
Preferential clearance of productive Acacia-dominated ecosystems was determined using digital land-system mapping and a 1994–1995 native vegetation remnant coverage from central Queensland. The previously mapped land systems are composed of complexes of land units, covering a range of productive potentials that are not individually mapped but defined according to their proportions within the land systems. Some land units were grouped into 11 ‘Acacia ecosystems’ composed of unique combinations of geology and vegetation dominated by brigalow (Acacia harpophylla F.Muell. ex Benth.), gidgee (A. cambagei R.T.Baker) or blackwood (A. argyrodendron Domin). Calculation of the remnant area of these Acacia ecosystems, assuming equal proportions of vegetation clearance of the land unit components within the land-system complexes (equal proportion calculation), was compared with a more accurate calculation based on interpretation of aerial photography (aerial-photograph calculation) data. The aerial photograph calculation of remnant area was 44% of the equal proportion calculation for brigalow on Tertiary clay and the ratio between these calculations was greater than 100% for only one Acacia ecosystem of relatively low production potential. The proportion of the remnant Acacia ecosystems relative to less productive ecosystems on tenures assigned to production (leasehold and freehold) was consistently lower than on other tenures. The use of mapping consisting of composite ecosystems with various production potentials for area-based assessment of vegetation clearance will overestimate the remnant areas of the relatively productive types unless a procedure such as that outlined here is used to correct for preferential clearance. This study provides near-complete and accurate data on the 1994–1995 status of Acacia ecosystems in central Queensland. Relative to their original area, values ranged from 6.8% for brigalow on Tertiary clay to 37.6% for gidgee–blackwood on alluvium.

The capital city of Central Kalimantan, namely Palangka Raya City, almost every year there are always forest and land fires that harm many people both economically, socially and environmentally which will certainly hinder the development of this city, Palangka Raya has a fire-prone area of 33,824 ha. Monitoring forest and land fires with manual field visits which can be very time consuming. To shorten the time and expand the ability to monitor forest and land fires, the use of Unmanned Aerial Vehicles (UAV) or drone images is one solution to map fire-prone areas in all fields. The aerial photography produced by the UAV is processed using the photogrammetric method to produce a responsible aerial photo map covering an area of 41.92 with 17 benchmark points to block fires in the UPR campus forest from spreading.

The authors showed that it is possible to quickly collect up-to-date information on the agricultural land condition using an unmanned aerial vehicle. It was noted that the use of ground control points increases the accuracy of project measurements, helps to compare the project post-processing results with the real measurements. (Research purpose) To compare the results of standard and high-precision post-processing of aerial survey data using ground control points. (Materials and methods) Aerial photography was carried out on a 1.1- hectare breeding field. The authors used DJI Matrice 200 v2 unmanned aerial vehicle with a GNSS L1/L2 receiver and a modified DJI X4S camera, five control points sized 50 × 50 centimeters and an EMLID Reach RS2 multi-frequency GNSS receiver. The results of scientific research into the use of ground control points during aerial photography were studied. (Results and discussion) It was found out that the error of georeferencing images obtained by an unmanned aerial vehicle without control points is significantly higher during the standard data processing compared to the high-precision one. The project error when using five control points is 3.9 times higher during the standard data processing. (Conclusions) It was shown that using ground control points it is possible to improve the project measurement accuracy, as well as compare the project post-processing results with the measurements on the ground. It was detected that the high-precision monitoring enables the use of fewer ground control points. It was found out that in order to obtain data with the accuracy of 2-4 centimeters in plan and height, at least 3 ground control points need to be used during the high-precision post-processing.

The purpose of the work is to investigate the digital elevation models of the mass grave of 1944, built on the basis of aerial and cartographic data of different times. The implementation of the task involves the construction of digital elevation models (DEM) on the territory of the Jewish mass grave in the city of Vynnyky and Italian prisoners of war near the city. On the territory of the Jewish mass grave in the city of Vynnyky, a DEM was created based on a stereo pair of archival aerial images obtained in 1944 and on the basis of aerial photography from a UAV conducted in 2015. Since archival aerial photographs did not contain orientation elements, they were geometrically transformed using the ErdasImagine software. After that, the stereo pair was processed in the program Digitals, where relief elements on the territory of the mass grave were obtained. Aerial photography from a UAV on the territory of the city of Vynnyky provided the data which was processed in the Agisoft PhotoScan software. It allowed us to create an orthophoto plan and an elevation map of the city territory. Elements of relief on the territory of the mass grave of 1944 and 2015 were imported into the Surfer software environment, where 3D digital elevation models were built. Since the territory of the grave did not have significant differences in height, and the relief was quite gentle, the method of constructing the DEM of the Natural Neighbor was chosen, which gave a positive result. Analyzing the digital elevation model and the vector map for 1944, the border of the mass grave is clearly distinguished, since the height difference between its edges and the rest of the territory is from 20 to 36 cm, depending on the section of the border. The analysis of the digital elevation models and the vector map for 2015 of the territory of the mass grave determined from the aerial image of 1944 showed that the characteristic height differences on the former border of the grave are observed only in the left-right corner of the grave and on a separate section of the right border. Height difference indicators range from 15 to 20 cm. It should be noted that height differences are also observed in the rest of the territory belonging to the mass grave and outside it. This can be explained by many years of human intervention and agricultural land use. With regard to the investigation of the mass graves of Italian prisoners of war near the city of Vynnyky, the modern territory is 100% wooded, which makes it impossible to apply aerial photography. Therefore, in order to compare the modern DEM with the stereo pair of aerial images of 1944, it was decided to conduct a ground tacheometric survey of the area in 2011. Tacheometric survey data was exported to the dxf exchange format, after which it was opened in Surfer and the DEM was built. In this case, digital elevation models were built using the Kriging method, since the area where the mass graves are located is quite hilly with a significant difference in elevation. According to the digital elevation models, 54 pits with burials that have survived to this day have been identified. The scientific novelty of the work consists in the development of the concept of combining disparate data for the construction of digital elevation models and the creation of a complete picture of the study of the territory of the object of historical and cultural heritage. The received data can be used by the relevant cultural heritage preservation departments of the Ministry of Culture of Ukraine for their further study.

The necessary sequence of stages has been developed and the unmanned technology for creating a digital elevation model by the example of the land use of Novosibirsk region has been implemented. The technology consists of a set of stages: reconnaissance of the terrain, fi xing reference signs, satellite measurements, aerial photography fl ights, processing the results of aerial photography and the construction of digital elevation model. The technological process was signifi cantly affected by unfavorable weather conditions - low clouds, gusty wind, high air humidity. Remote sensing study with the use of unmanned aerial vehicle of the Supercam S 250 F type made it possible to create a large-scale orthophotoplan and a digital elevation model on the farm territory (M 1 : 1000). For photogrammetric processing of digital data obtained on the farm, a two-stage method of satellite determination was used. The essence of this method was to obtain a large number of satellite measurements in a static mode and further statistical processing. For statistical processing of satellite measurements, information was used on the coordinate location of two base ground stations of the Novosibirsk Region satellite network - Kochenevo and Novosibirsk. Remoteness of support points from the ground satellite station of Novosibirsk was at a distance of over 90 km. As a result of equalization calculations, the obtained average square displacement errors of the planned and high-altitude position of the support points in various test sites were under 0.02 m in the plan, and under 0.03 m by height. In the process of photogrammetric processing of the results of aerial photography with the use of unmanned aerial vehicle, the tasks of transferring the position of points on a digital image in the pixel coordinate system into the coordinate system of the area, building digital irregular (TIN, Triangulated Irregular Network) and regular (DEM, Digital Elevation Model) surface models, and based on them, textured terrain models (TTM, Textured Terrain Model) and orthophotoplans, were solved.

Aerial photographs have been systematically collected from as early as the 1930s, providing a unique resource to describe changes in vegetation and land cover over extended periods of time. However, their use is often limited by technical constraints, such as the lack of ground control information and precise camera parameters, which hamper an accurate orthorectification of the raw imagery. Here, we describe the historical aerial photographs orthorectification (HAPO) workflow, based on a conventional photogrammetric procedure (the direct linear transformation (DLT) Method), integrated as a geographic information systems (GIS) procedure, in order to perform the image orientation and orthorectification, thereby converting historical aerial imagery into high-definition historical orthoimages. HAPO implementation is illustrated with an application to a rugged landscape in Portugal, where we aimed to produce land-cover maps using an aerial photograph coverage from 1947, as part of a study on long-term socioecological dynamics. We show that HAPO produces highly accurate orthoimages and discuss the wider usefulness of our framework in long-term socioecological research.

The article is devoted to the study of the technology of inventory of green areas with the use of the latest technologies: unmanned aircraft and satellite navigation systems. The topic of the article is relevant, because reliable and up-to-date information on the quantitative and qualitative state of green spaces of settlements is obtained during their inventory and arrangement. As a result of conducting an inventory for each green economy object, a passport of the green economy improvement object is drawn up. The following documents are attached to the passport: an inventory plan on a given scale and a working diary of accounting for greenery. One of the links in the inventory of green spaces of the settlement is sub-field survey, which is currently performed using unmanned aerial vehicles and satellite technologies and in turn consists of topographic and geodetic and aerial photography, and is divided into the following stages: information collection; preparatory work; chamber work. At the stage of collecting information on the object of work, the available urban, land management, geodetic and cartographic materials are analyzed. The second stage – preparatory work, consists of field surveying and aerial photography. Field geodetic works include reconnaissance of the area and the development of plan-height substantiation of the aerial survey area. Field aerial photography consists of creating a flight project, pre-flight training of a quadcopter and direct aerial photography. In-house works are the third final stage, which consists of: processing of aerial photographs; creation of a polygonal terrain model; creation of orthophoto in scale 1: 500; creation of a topographic plan in the Digitals software package; reconnaissance of the area to clarify the spatial and attributive data on greenery; creation of the adjusted topographic plan of inventory of green spaces. It is also recommended to make adjustments to the obtained topographic plan, during which the position of trees in places where a large error was detected and outlines were formed was measured by linear notches with reference to rigid contours. At the same time it is necessary to clarify the species of trees according to the symbols. The digital information obtained in this way about green plantations can be used to calculate the cost of work on the development of the passport of the facility and inventory plan for a given area or create and develop geographic information portals of green areas of individual territories or settlements.

In this paper, attempt has been made to prepare landuse map for the district of Brahmanbaria, situated in the east-central part of Bangladesh using remote sensing technique. The multi-spectral Landsat TM data for 3 November 2002, 15 December 2004, 01 February 2002, 14 March 2003 and some aerial photographs of December 2000 have been used for land-use mapping for major three crops namely aman rice (late July - early November), winter (rabi) crops and winter (boro) rice. The imagery covers the growing seasons of the above crops, where multi-spectral and multi-temporal signatures for the green vegetations have been shown in spatial domain. The interpretation of the aerial photographs have also been performed and prepared GIS layers containing the water bodies and settlements. All the signature files including the interpretations of aerial photographs have been combined to produce a composite file in GIS layers. These layers were then combined to prepare the landuse maps including the three major crops cultivated round the year. Moreover, the landuse map of Akhaura upazila was compared with the land-type map and a relation of the landuse with the land-type has also been derived. The extracted feature files corresponding to spectral signatures have been overlaid to estimate the distribution of three major crop types in the study area. The result implies that all the three major crops like, aman, rabi and boro were cultivated in the same land which was 9.2% of total land area. Similarly, areas under double and single crops were also estimated and the result revealed that all the three crop types cover 68.3% of the total land area of Brahmanbaria district.

ABSTRACTThis paper reports on the first and highly effective use of Light Detection and Ranging (lidar) technology to document Chaco roads, monumental linear surface constructions of the precolumbian culture that occupied the Four Corners region of the American Southwest between approximately AD 600 and 1300. Analysis of aerial photographs supplemented by ground survey has been the traditional methodology employed to identify Chaco roads, but their traces have become increasingly subtle and difficult to detect in recent years due to the impacts of natural weathering, erosion, and land development. Roads that were easily visible in aerial photography and on the ground in the 1980s are now virtually invisible, underscoring the need for new, cutting-edge techniques to detect and document them. Using three case studies of the Aztec Airport Mesa Road, the Great North Road, and the Pueblo Alto Landscape, we demonstrate lidar's unprecedented ability to document known Chaco roads, discover previously undetected road segments, and produce a precise quantitative record of these rapidly vanishing features.

We used aerial photography and dendrochronological data to quantify the amount of, and the rate of change in, the woody-vegetation cover between 1948 and 1997, and historical data to document land-use changes during this time. Aerial photographs indicated that in 1948, 56% of study area had <50% cover of woody plants. By 1997, 90% of the study area had >50% woody-plant cover. The native shrub Leptospermum scoparium J.R. Forst & G. Forst (Myrtaceae) was predominantly responsible for the increases in cover. Demographic analyses indicated that recruitment has been ongoing rather than episodic; large numbers of shrubs, however, have recruited since 1994. We hypothesise that the vegetation changes observed are likely a response to changes in land-use that have occurred since European occupation. Increased woody-plant cover followed the removal of sheep grazing in the long-term absence of fire. It is very likely that the long history of stock grazing, coupled with selective logging and associated soil disturbance, initiated a change in understorey vegetation by reducing competitive native tussock grasses and fuel loads to carry fires and this reduction was initially responsible for the encroachment of shrubs into the woodland. Recruitment has been ongoing in the absence of any recent land-use changes (most utilisation ceasing after the declaration of National Park status in 1984) and hence, this transformation from species-rich herbaceous woodland to shrubby woodland is expected to continue in the future.

Bananas are the world’s most popular fruit and an important staple food source. Recent outbreaks of Panama TR4 disease are threatening the global banana industry, which is worth an estimated $8 billion. Current methods to map land uses are time- and resource-intensive and result in delays in the timely release of data. We have used existing land use mapping to train a U-Net neural network to detect banana plantations in the Wet Tropics of Queensland, Australia, using high-resolution aerial photography. Accuracy assessments, based on a stratified random sample of points, revealed the classification achieves a user’s accuracy of 98% and a producer’s accuracy of 96%. This is more accurate compared to existing (manual) methods, which achieved a user’s and producer’s accuracy of 86% and 92% respectively. Using a neural network is substantially more efficient than manual methods and can inform a more rapid respond to existing and new biosecurity threats. The method is robust and repeatable and has potential for mapping other commodities and land uses which is the focus of future work.

As a cultural heritage, Site of Keraton (Palace) Pleret becomes an essential relic in Javanese history and culture to preserve and deliver ancient information for the next generation sustainably. On the other hand, this preservation is dealing with quite rapid built-up area development. Mapping can be a significant effort as primary data in cultural preservation management. This study aims to make a detailed site map of the Keraton Pleret and identify the existing land use in each site component. Through remote sensing data interpretation and analysis, identification and mapping of archaeological sites done by matching previous archaeological documents, field conditions, digital orthophoto from aerial photography, and digital topographic data (digital surface models, DSM). Site components were identified firstly by matching the existence of the street network and river from a topographic map with orthophoto to obtain site orientation based on artificial infrastructure and existing natural features. It was followed by matching between Keraton Pleret blueprint document, previous archaeological information, and orthophoto to identify and locate each site component. Existing land use information obtained by orthophoto interpretation. Data analysis shows the compatibility between spatial data used in this research and previous documents to identify components and result in Keraton Pleret site map. At present, most of the Keraton Pleret site area has been converted to buildings and paddy fields, strengthen the need for archaeological sites management which alongside community activities.

Abstract. Conventional topographic maps are still important for many applications, such as land planning, but require frequent updates, which involve high costs and are not easy to accomplish. There are however many advances in Photogrammetry that are not always exploited to their full potential in a real map production environment. The traditional process involves aerial triangulation with ground control points, stereo restitution in digital photogrammetric workstations and field completion. The process is very time-consuming and expensive and map update is many times not done with the frequency required by users.This paper describes the implementation of an improved methodology for very frequent revision of the Portuguese map series of scale 1:25,000 making use of conventional digital aerial photography, which now is acquired on a regular basis for all the country. Vector features are digitised in monoscopic mode, in a GIS environment, over true orthophotos. These can be produced in a largely automated manner, using direct georeferencing data, and with minimal ground control only for vertical adjustments. Revision time and cost can be significantly reduced, keeping acceptable accuracy standards. That will satisfy the users that require the traditional high standards of the topographic map series for land panning.Additionally, for the task of field data collection of information that cannot be obtained from aerial photographs, a method is being applied to make use of video data collected in the field along roads with action cameras, with GPS. Operators can confirm or identify attributes of objects along, or near roads, such as power lines.

Land use changes and land intensification has played a more and more important role in food production. The environment has been influenced by it greatly. Land use data were derived from several sources: aerial photographs, current land use maps, Second National Soil Survey (SNSS) map, and fieldwork. The aerial photographs, 1:50,000 for both 1980 and 2006 were obtained from the Department of Surveys and Mapping (DSM). Bulk soil samples were collected at 79 sites across Quzhou district. Samples were collected again at the same locations in 2000 and 2006. To compare the soil data of 2006, 2000 and 1980, latitude and longitude of the sampling locations were recorded using the Global Position System at the time of soil collection. The samples site selection was done on behalf of the Second National Soil Survey. A great change had taken place in land use and land use intensification. The changes, which have converted natural landscapes into the use for human, have made a large proportion of the Quhzou’s landscape change greatly.

The international initiatives developed in the context of combating global warming are based on the monitoring of Land Use, Land Use Changes, and Forests (LULUCEF). Determination of changes in land use patterns is used to determine the effects of greenhouse gas emissions and to reduce adverse effects in subsequent processes. This process, which requires the investigation and control of quite large areas, has undoubtedly increased the importance of technological tools and equipment. The use of carrier platforms and commercially cheaper various sensors have become widespread. In this study, multispectral camera was used to determine the land use pattern with high sensitivity. Unmanned aerial flights were carried out in the research fields of Kahramanmaras Sutcu Imam University campus area. Unmanned aerial vehicle (UAV) (multi-propeller hexacopter) was used as a carrier platform for aerial photographs. Within the scope of this study, multispectral cameras were used to determine the land use pattern with high sensitivity.

An unmanned aerial vehicle (UAV) was used to capture high-resolution aerial images of crop fields. Software-based image analysis was performed to classify land uses. The purpose was to help relevant agencies use aerial imaging in managing agricultural production. This study involves five townships in the Chianan Plain of Chiayi County, Taiwan. About 100 ha of farmland in each township was selected as a sample area, and a quadcopter and a handheld fixed-wing drone were used to capture visible-light images and multispectral images. The survey was carried out from August to October 2018 and aerial photographs were captured in clear and dry weather. This study used high-resolution images captured from a UAV to classify the uses of agricultural land, and then employed information from multispectral images and elevation data from a digital surface model. The results revealed that visible-light images led to low interpretation accuracy. However, multispectral images and elevation data increased the accuracy rate to nearly 90%. Accordingly, such images and data can effectively enhance the accuracy of land use classification. The technology can reduce costs that are associated with labor and time and can facilitate the establishment of a real-time mapping database.

There is considerable interest in the fragmentation and loss of natural and semi-natural habitats, but few studies have examined the dynamics and mechanisms of change. A temporal analysis of landscape change on the South Downs in Sussex, UK, provides a clear description of the process of change over the 20 years 1971–1991. Transition probabilities were calculated from digital interpretations of an aerial photography time series of West Sussex. The analysis enabled quantitative comparison of landscape mosaics within different landscape ecoregions and under different management regimes to be made. Past changes in land use have produced a fragmented downland landscape. The key land conversion sequences identified show a substantial transition towards arable production, often at the expense of the internationally and nationally important unimproved grassland systems. A geographical information system facilitated greater understanding of the environmental and topographical characteristics of land converted to arable and other uses, and highlighted areas for protection and potential restoration. The patterns of land-use conversion observed in the study provide a landscape-scale planning tool for assessing the potential impact of agri-environmental policies, plans, and programmes in semi-natural grassland habitats.

This study uses sequential aerial photography to identify environmental changes. The interpreted aerial photos constitute a data-bank of past and present land cover/uses.* Substantial changes have been observed in the areas of cultivation, woody cover, and bare ground.An increased 449.9% of the surveyed area has been cleared for cultivation during the last 30 years, while 77.2% of the former woodland has been destroyed during the same period, contributing to a 15.6% increase in grassland. Bare ground increased by 33.1%. Increased cultivation is caused by increase in the population of subsistence farmers and mechanization. Expansion of cultivation and overexploitation of woody resources (fuel-wood and building materials) are the causes of decline in the woody vegetation. As consumption of woody resources exceeds natural regeneration, woody cover is gradually replaced by grasslands.Diminution of the woody vegetation results in shortage of fuel-wood and building materials and consequent misery to the local people. Expansion of cultivation reduces grazing-land, leading to overstocking and overgrazing. Extensive cultivation, based on soil ‘mining’, subjects more and more land to physical and chemical soil degradation, leading in turn to decline in soil fertility and crop yields. Both overgrazing and extensive cultivation accelerate soil erosion in the area, reducing available cropland, while siltation and flooding cause serious damage to property and infrastructure.Lack of effective land-use planning, uncontrolled population growth, and introduction of the Tanzanian village agricultural production system in a semi-arid area, have contributed to the present deplorable state of affairs. In general, the area shows increasing environmental degradation and resource depletion, while very little conservation effort is being made to reverse the trend. These results indicate that a sustainable resource management plan is urgently needed for the area.

The Purpose. The purpose of the study is to prove the effectiveness of the use of unmanned aerial vehicles for the preparatory stage of evaluation works. In the process of development of modern methods of remote sensing of the territory of populated areas, the problem of using unmanned aerial vehicles for real estate evaluation is gaining relevance. Aerial surveying has been an effective tool for geodetic work, geophysical research and various types of monitoring for several decades. Modern technologies for creating topographic and cadastral plans are based precisely on the use of digital aerial photography materials [Burshtynska H., Stankevich S., 2013]. However, the cost of using airplanes and helicopters for local large-scale shooting is an order of magnitude higher and therefore. an alternative solution is to use UAVs for property valuation. The Methodology. The methodology is based on the need to use UAVs to assess the market value of real estate. The creation of large-scale plans of rural settlements based on data obtained with the help of UAVs is necessary for the design of master plans [Glotov V., Korduba Yu., 2011; Glotov V., Gunina A., 2014]. And this, in turn, is connected with land accounting and setting boundaries in a certain region, as well as the need to assess the market value of real estate. Unmanned aerial vehicles are widely used for aerial photography, as they are an inexpensive alternative to traditional filming from airplanes, helicopters, hang gliders, and satellites. In addition to high economic efficiency, i.e. a tenfold decrease in price, UAVs have additional advantages compared to traditional aerial and space shooting. The Results. The conducted studies prove the importance of using UAVs in real estate evaluation. The purpose of using a UAV is to obtain images of the territory with given characteristics. It is known that aerial photography, as a type of remote sensing of the earth, is an economically and technologically justified way of collecting spatial information, the basis for creating cadastral plans and maps, three-dimensional models of the terrain and terrain [Glotov V., Tserklevych A., etc., 2014]. It is proven that the efficiency of the proposed method exceeds by 36% the traditional methods of real estate evaluation. Scientific Innovation and Practical Significance. For the first time, research was carried out related to the possibility of using UAVs to estimate the market value of real estate. The article proves that the use of unmanned aerial vehicles at the stage of collection and analysis of initial data will make it possible to reduce the cost of determining the geometric characteristics of the object of evaluation by ten times compared to traditional geodetic methods, as well as speed up the process of selecting similar objects for the purpose of building mathematical models determining the market value of the relevant real estate segment. It has been proven that unmanned aerial vehicles have significant advantages compared to traditional methods of filming, namely: the possibility of obtaining ultra-high resolution (units and tenths of a centimeter) on the terrain; the possibility of detailed filming of small objects and small areas where it is completely unprofitable or technically impossible to do it in other ways, for example, in the conditions of urban development; mobility; high efficiency; environmental cleanliness of flights; high economic efficiency (decreasing the cost of work tenfold), etc.
