Abstract:

As the largest developing country, China has permanently attached great importance to cultivated land protection. However, due to the different rules of cultivated land identification in the second and third national land surveys, the cultivated land area in the two surveys has changed greatly. Some agricultural lands in the south, such as plantations, forests, grasslands, aquaculture ponds, etc., belonged to cultivated land during the second survey, but they were identified as non-cultivated land in the third national land survey. This change has led to a sharp reduction in the area of cultivated land in some places. In order to calculate the actual change in the area of cultivated land since the second survey and provide a reasonable basis for the standard of cultivated land protection, this paper takes Gaochun District, a developed area in China, as an example; interprets the images of the second national land survey period with the deep learning network HRNet; and compares the results with the second and third national land survey rules. The results show that the actual reduction of cultivated land in Gaochun District in the past ten years accounts for 35.1% of the reduction of cultivated land in the two land surveys, while the reduction of cultivated land caused by the change of cultivated land identification rules accounts for 64.9% of the reduction of cultivated land in the two land surveys, indicating that the significant reduction in local cultivated land was mainly caused by the changes in the rules, and these cultivated land reduction behaviors existed before the second survey.

Abstract:

After a brief review of floristic classifications, ecological survey, as carried out in Quebec, is described. Three stages of development of ecological survey over the past twenty-five years are identified: (1) the pioneer work of Jurdant; (2) major ecological surveys from the late 1960s to the late 1970s; and (3) the diversification of the groups involved in ecological land surveys beginning in the 1980s, including universities, the Quebec Environment Department (MENVIQ) and the Quebec Department of Energy and Resources (MER). Intended for use in integrated land management, ecological survey must be an effective integrator of the various ecological evaluations; the information must be easily communicable and the methodology must be flexible. Ecological land classification has two dimensions: (1) taxonomic; and (2) cartographic. In the taxonomic units, the ecological region, the ecological type and the ecological phase are identified. In cartographic terms, local (ecological phase and type), regional (ecological system and subsystem) and national (ecological district and region) resolution is identified.Quebec universities, MER and MENVIQ are presently involved in ecological land surveys. The new Forest Act, which was enacted in 1986 and which provides for sustainable yield and more intensive forest management, is a major force behind the promotion of the use of ecological inventories as the basis for management activities. Mapping of the ecological regions (1:1,250,000) has almost been completed in Quebec. Total coverage of the commercial forest as a function of ecological districts (1:250,000) could be completed within five years, and the mapping of ecological types (1:20,000) could be completed in 20 years at a rate of 10,000 km2 a year. Although in the past ecological land surveys have been used primarily for environmental impact analyses (for instance, the installation of hydroelectric equipment and transportation corridors), the ecological framework is presently being used to prepare development plans for a number of regional county municipalities (RCMs). Pilot projects are under way to assess the potential applications of the ecological framework to forestry as part of intensive management efforts. Improvements are needed in both the accessibility of the information provided by the ecological framework (maps, site guides) and the development of interpretative tools for silvicultural measures. Key words: ecological survey, ecosystem mapping, ecological land classification, forest ecology, forest site classification, Quebec.

Abstract:

Major cities and urban areas are beginning to develop and use 3D properties and public facilities. Consequently, 3D cadastral surveys are increasingly being employed for strata unit ownership registration as a part of land administration services. At present, most national land information systems do not support 2D and 3D cadastral visualizations. A field survey or validation survey is required to determine the geometry of 3D spatial units for property registration. However, the results of 3D surveys and mapping are not stored in the land information system. This work aims to integrate 2D and 3D geospatial data of property units collected from cadastral surveys with their corresponding legal data. It reviews the workflow for the use of 3D survey data for first-titling of 3D properties in Indonesia. A scenario of use and a prototype were developed based on existing practices and the possibility of extending Indonesia’s Land Administration Domain Model (LADM) to represent 3D units. Data submitted to the prototype as 3D geometries was survey data from 3D cadastral surveys or validation surveys utilizing terrestrial survey methods. The prototype used PostGIS and Cesium Ion to store 3D geometries of data from six 3D surveys. Registrars in local land offices could use the prototype to undertake strata unit registration that establishes a relationship among geospatial features and their survey documents and legal documents. Cesium JS was used as a 3D browser, customized as a web application, to manage and visualize 3D survey data to support strata title registration. The results demonstrate that the first titling of 3D cadaster objects could be conducted and properly visualized in Indonesia by extending the existing LADM with more support for 3D spatial representations and survey documents.

Abstract:

Knowledge of physical characteristics of land is fundamental for rational land evaluation and land use planning, both in developed and undeveloped regions. A review of two land classifications, parametric and physiographic approaches, is carried out. The parametric approach classifies on the basis of selected land attributes determined by land use or uses in question. Its employment may range from general purpose surveys which are considering many attributes, to classification on narrower basis for special purposes. The physiographic approach, on the other hand, classifies land rather than its specific attributes. Each land unit identified in this way is therefore considered to be relatively homogeneous in overall characters. Both approaches have had varying merits depending on the goal and circumstances of the land evaluation. On a detailed study required by most practical purposes, both approaches theoretically meet the requirements of land classification. Of both approaches, it was concluded that physiographic approach had the advantage of being rapidly implemented whereas, the parametric approach, whilst slower in use and applicable only in localized studies, yielded more reliable results. In reality, however, distinction between both approaches is not so clear-cut because they can be combined with advantage. Their advantages and disadvantages relative merits also be assessed in related to three problems of land classification: (1) complexity of land, (2). extent of land-units, and (3) associations of land-units. The two approaches are really not alternatives and can, in fact, be combined with profit, since the relative advantage of each varies with circumstances. Physiographic approach offers a possibility on more rapid survey at relatively low cost, as needed in most undeveloped regions. Its reliability is consistent for reconnaissance investigation and, with moderately close sampling, for semi-detailed surveys. It has an additional advantage of enabling a survey with diverse specialists. For a detailed survey, however, greater precision and reliability of parametric approach is preferable. In practice, therefore, both methods are best combined to reinforce each other.

Abstract:

The Jameson Land region contains the largest muskox population in Northeast Greenland. In the period 1980-1990, late winter population size averaged 3,645. A late winter 2000 survey estimated ca. 1,705 muskoxen. Although no further late winter surveys for muskox abundance have occurred since, there have been two summer bird surveys, which recorded incidental observations of muskoxen, i.e., 607 in 2008 and 610 in 2009. We report on muskox observations obtained in a subarea of Jameson Land during the summer 2016 ground survey for birds. Although in the 1982-2000 period this subarea averaged 1,153 ± 346 muskoxen, we observed 138 individuals and a low calf number. The few muskoxen observed and poor calf production suggest population decline. We briefly discuss possible factors that could influence muskox mortality and population abundance. Surveys specific to muskoxen are necessary to ascertain current population abundance, demographics and trend.

Abstract:

Abstract An autonomous unmanned helicopter (AUH) survey is a useful tool for monitoring the distribution of ambient dose equivalent rates. However, the AUH survey method was developed for plane permeable fields such as agricultural land, and its applicability to urban areas is unclear. In this study, the applicability was investigated by comparing the results of AUH and ground-based surveys conducted in suburban areas, including residential and agricultural lands. The results of both surveys broadly agreed with each other within a factor of 2 in the range independent of land use, and the factor was the same as that reported for plane permeable fields. These results suggest that AUH surveys are applicable in urban areas. The measurement uncertainty of the AUH survey was largely affected by the patchy and local distribution of ambient dose equivalent rates on the ground and differences in the fields of view, rather than land use.

Abstract:

In September 2014 the Applied Geomatics Research Group (AGRG) completed a third aerial mapping campaign of Sable Island. The AGRG first mapped the island in October 2002 with an aerial photography survey. Then in August 2009 AGRG conducted an aerial photography and Light Detection And Ranging (LiDAR) survey. Five years later these same technologies were deployed again. Each of these surveys led to an orthophoto mosaic of the island and a mapping of the land cover. The 2009 and 2014 surveys also mapped the island’s topography using Digital Surface Models (DSMs) derived from the LiDAR data. Ground-truthing efforts associated with each survey provided data to assist with the interpretation and validation of the results.The repeat surveys resulted in an excellent opportunity to quantify the topographic and land cover changes that have occurred on the island. The mapped results provide a comparison of how and where these changes have occurred over the years. AGRG is working with Parks Canada to better understand how the topography and land cover are changing. This understanding will contribute to Parks Canada Ecological Integrity monitoring program for Sable Island and inform the management planning process for one of Canada’s newest national parks.

Abstract:

The state of Missouri, USA offers a unique opportunity for tree planting under several federal conservation programs. However, many landowners remain hesitant to enroll and take land out of agricultural production. This study explores the willingness of landowners to adopt agroforestry systems with food producing tree and shrub species through federal conservation program funding using mail and online surveys. Surveys followed the Dillman Tailored Design Method to collect data on landowners’ farm characteristics, production practices, and land management choices. Survey participants were sampled on a county basis within each of the six major geographic regions of the state. Twelve counties were randomly selected, and surveys were mailed to a proportional sampling of farm addresses gathered from each of the county tax assessor offices. The goal of the survey was to (1) identify landowners’ current land management practices and goals, (2) understand landowners’ perceptions of and preferences for different planting plans for their farm, and (3) capture landowners’ interest in participating in conservation programs to assist in the planting of trees and shrubs on their land. Our analysis of this survey found that landowners are receptive to agroforestry plantings, rating them higher on average than traditional agricultural land management practices. Landowner age, past participation in a conservation program, and presence of marginal land all had significant correlation with willingness to adopt agroforestry. The inclusion of technical assistance or federal conservation funding was found to increase the willingness of landowners to plant multifunctional agroforestry designs.

Abstract:

This article outlines the results of two related but distinct aspects of fieldwork: a geophysical survey of the Rhynie cropmark complex and a small targeted excavation conducted in 2005–6, which are both part of the Rhynie Environs Archaeological Project (REAP). The geophysical surveys included a substantial gradiometer and a smaller resistivity survey that aimed to characterise and explore the extent and survival of archaeology around the Craw Stane Pictish symbol stone (NJ42NE 35) and two other symbol stone findspots. The results showed several discrete anomalies; one of these was targeted by a small-scale excavation and proved to be a burnt Middle Bronze Age timber structure. This article describes the geophysical survey results and the excavation of the MBA structure and sets both within their landscape context.

Abstract:

Abstract Unmanned Aerial Vehicle (UAV) drones and Total Stations are two of some methods and tools used to conduct surveys on areas or building buildings. A UAV is a flying machine that functions with remote control by the pilot or can control itself, uses aerodynamic laws to lift itself, can reusable and can carry certain payloads. A total station is a device that is a combination of electronic theodolite, Electronic Distance Meter, and software that serves as a data collector and processor. The implementation of land surveying is one of the stages of the implementation of infrastructure development. Land survey itself is a way or method to evaluate land to get data directly from the field. Survey activities consist of field activities, making data analysis, interpretation of objectives and making survey reports. In this modern period, the technology to conduct land / land surveys often develops, namely with the total station and the use of UAV drone technology. The study aims to analyse and compare the capabilities of UAV Drones and Total Stations.

Abstract:

Long-term environmental monitoring surveys are designed to achieve a desired precision (measured by variance) of resource conditions based on natural variability information. Over time, increases in resource variability and in data use to address issues focused on small areas with limited sample sizes require bolstering of attainable precision. It is often prohibitive to do this by increasing sampling effort. In cases with spatially overlapping monitoring surveys, composite estimation offers a statistical way to obtain a precision-weighted combination of survey estimates to provide improved population estimates (more accurate) with improved precisions (lower variances). We present a composite estimator for overlapping surveys, a summary of compositing procedures, and a case study to illustrate the procedures and benefits of composite estimation. The study uses the two terrestrial monitoring surveys administered by the Bureau of Land Management (BLM) that entirely overlap. Using 2015–18 data and 13 land-health indicators, we obtained and compared survey and composite indicator estimates of percent area meeting land-health standards for sagebrush communities in Wyoming’s Greater Sage-Grouse (Centrocercus urophasianus) Core and NonCore conservation areas on BLM-managed lands. We statistically assessed differences in indicator estimates between the conservation areas using composite estimates and estimates of the two surveys individually. We found composite variance to be about six to 24 units lower than 37% of the survey variances and composite estimates to differ by about six to 10 percentage points from six survey estimates. The composite improvements resulted in finding 11 indicators to statistically differ (p <0.05) between the conservation areas compared to only six and seven indicators for the individual surveys. Overall, we found composite estimation to be an efficient and useful option for improving environmental monitoring information where two surveys entirely overlap and suggest how this estimation method could be beneficial where environmental surveys partially overlap and in small area applications.

Abstract:

Performing engineering surveys is a mandatory part of the development of technical documentation on land management. Surveys allow to confirm the accuracy of the performed geodetic or topographic survey. In particular, the accuracy of determining the geodetic coordinates of the turning points of the boundaries of the land, to link the turning points of the boundaries of the land to the geodetic points of the State Geodetic Network of Ukraine. The main purpose of the article is to reflect the main components of engineering surveys as part of land cadastral works in preparation of land for registration in the database of the State Land Cadastre. The coordinate basis for land management is the State Geodetic Reference Coordinate System USK-2000, the geodetic basis for land management – points of the State Geodetic Network 1-3 classes, points of geodetic networks of compaction 4 class, 1 and 2 categories, points of the surveying network. The coordinates of the points of the State Geodetic Network of Ukraine, geodetic networks of condensing and turning points of the boundaries of geospatial objects are determined by rectangular coordinates (x, y) in the Gauss-Krueger projection in the USC-2000 coordinate system or local coordinate systems. related to the USC-2000 coordinate system. The control of the differential field of coordinate corrections when working with the use of RTK technologies is carried out at least at the two nearest points of DGM and GMZ, the coordinates of which are obtained from the administrator of the geodetic data bank. The difference in the values of the coordinates of control points should not exceed 0.1 m in cities of regional importance, 0.2 m - in other cities and towns, 0.3 m - in rural areas and 0.5 m - outside the settlements.

Abstract The use of UAV (Unmanned Aerial Vehicle) in land surveys and the implementation of BIM (Building Information Modeling) in the construction world has begun to be used frequently, both in the manufacture of infrastructure and building structures. The purpose of this study was to determine the effectiveness of the use of UAV in land surveys with parameters of cost, quality and time, and to find out whether the land survey can be integrated with a 3-dimensional design with applications related to BIM. This study uses secondary data in the form of aerial photo data and 3-dimensional BIM design data, which produces some data such as 3-dimensional data from the layout of a land using UAV, with a fairly good level of effectiveness compared to previous studies. In addition, the results of the integration of a 3-dimensional map of a land survey using a UAV with a 3-dimensional design of the BIM method can provide a visualization of the design form with actual conditions in the field.

Abstract:

We formulate and solve a mathematical programming optimization model to find a minimum cost solution for an orthogonal split‐spread design in a 3‐D land seismic survey. The model contains decision variables on source and receiver location spacings, the amount of receiver equipment, and the production rate of the seismic crews. The model includes operational constraints for source and receiver movements. It also includes geophysical constraints for fold coverage, offset, and azimuth. To demonstrate the efficacy of the model, we include an example and solve it using the nonlinear optimization solver in Microsoft Excel. The model results demonstrate the classic trade‐off between source and receiver points to satisfy the geophysical requirements. In addition, we conduct sensitivity analysis on an important production parameter: the maximum number of source points that can be shot per day. We show that although changes to this parameter do not impact the decision variables, such changes do have a significant effect on the total cost of the survey.

Abstract:

The general methods of land survey for the purposes of technical inventory of real estate units don’t allow creating visual materials and forms of real estate objects elements that can have some errors. The new method of land survey with the stereo photography and GNSS coordinating of station is free of this weaknesses. The land surveys of object must be made with photogrammetric constructеs, which consist of 3, 4 or 6 snapshots. Stations must have noncollinear position. Minimal base lines must be calculated according to acceptable errors of buildings measurements. The research shows that all photogrammetric constructеs are of equal accuracy. The photographing with 4 or 6 stations is more informative because of different lines of sight. The result of this surveys is a 3D model. Measurements of forms of real estate objects elements with 3D models have high accuracy. The survey examples of different objects shows high accuracy results of 2D and 3D measurements, which are made with 3D model. The implementation of the method of land survey with the stereo photography for the purposes of technical inventory of real estate objects makes real progress in the creation of 3D cadaster.

The research was conducted from March to November 2022. This research was a descriptive study, that used the method of collecting data using an investigative survey. Data analysis carried out investigations of sharecroppers, mapping and situation surveys, surveys of land use conditions, and investigations of land tenure status. The results of the study stated that the impact of the Swamp Land Optimization program on Community Socio-Economic Empowerment, namely contributing to farmers having their rice farming land area, strengthening the structure of farmers’ income sourced from on-farm activities, and farmers being able to meet their own needs. Some of the obstacles that were still experienced by farmers are the lack of water sources to irrigate paddy fields, the condition of damaged road infrastructure, low production yields, infertile agricultural land, pests and plant diseases, and others. Advice for policymakers is to maintain the sustainability of swampland optimization activities because it provides optimal assistance to farmers in rice farming in swampland.

Abstract. Today when online satellite images are just a click away, access to geographic information showing the latest images of the globe has dramatically expanded, and historico-geographic research based on such information is flourishing. However, in the study of Chinese history, historical research employing GIS or similar technologies is still in its infancy, since “historical” geographic information with a high degree of precision are lacking. From within the ambit of Chinese geographic information, this report specifically highlights aerial surveys effected during the Republic of China era. To start, we review the history of domestic aerial surveys during R. O. C. period. Then, focusing on Nanjing as an example, we proceed to introduce maps that were actually created based on aerial surveys.Chinese aerial surveys date back to around 1930. At the Nationalist Party’s General Assembly in 1929, partisans proposed for the need for aerial surveys. In 1930, the “Aerial Photography and Survey Research Team” was formed within the General Land Survey Department at General Staff Headquarters (National Army of the Republic of China). Consequently, foreign technicians were invited to provide relevant education/training. In June 1931, China’s pioneer initiative in aerial photography took place in Zhejiang province. The aim of aerial surveys in those early days was to create maps for military purposes. Between 1932 and 1939, topographic maps of fortifications located in areas such as the Jiangnan district were prepared. Further, starting from around the same period until the Sino-Japanese War, land registry maps based on aerial surveys were also produced. After the Sino-Japanese War ended, the above-mentioned directorate handed over responsibility for aerial surveys to the Naval General Staff. However, in 1949 the Chinese Communist Party confiscated the maps theretofore produced.Although the aerial photographs and the geographic information produced therefrom during the R. O. C. era were seized by the People’s Republic of China, in actuality, some had previously been transferred to Taiwan. The topographic maps of the Nanjing metropolitan area (一萬分一南京城廂附近圖), based on aerial surveys and drawn in 1932, are currently archived at Academia Historica in Taipei. Comprising a total of 16 sheets, these maps were drawn on a scale of 1:10,000 by the General Land Survey Department.Similarly, other maps (各省分幅地形圖) produced by the General Land Survey Department, comprising a total of 56 sheets and partly detailing Nanjing, are now in the possession of Academia Sinica in Taipei. There was no information about photographing or making in these maps. But almost the same maps were archived at Library of Congress in Washington D. C. According to those maps at LC, based on aerial photographs taken and surveys conducted in 1933, these topographic maps (1:10,000 scale) were completed in 1936.The examples introduced above are topographic maps based on aerial photography. However, starting in 1937, land registry maps were also created. Detailing the outskirts of Nanjing (1:1,000 scale) and comprising a total of 121 sheets, they are now archived at Academia Historica. While the land registry maps were produced in 1937, supplementary surveys were effected following the Sino-Japanese War in 1947.Since the geographic information based on aerial surveys during the R. O. C. era in China were precise, they can serve as a source of manifold information. This report only delved into information developed by the Government of the R. O. C., but it is becoming evident that U. S. Armed Forces and Japan also produced geographic information of their own based on aerial surveys. If the comprehensive panorama captured by all three protagonists can be illuminated, further advances in Chinese historico-geographic studies employing geographic information will be forthcoming.

Abstract:

Boundary resurveys have become necessary in most mining communities of Ghana, especially, Tarkwa and its environs due to pressure and alteration in land use and land cover by mining operations. Most of the boundary markers (pillars, trees, streams, hills, valleys, footpaths, etc.) used in the past have been destroyed by mining and other associated activities. This has led to many disputes about ground boundaries and ownership of land tracts in the area. To curb the incidences of such conflicts, it has become important to have more reliable and scientific demarcations and surveys of the old boundaries and owners of land tracts in the area for registration, using modern technologies in land surveying. Equipment and methods used over a century ago to mark and describe land boundaries in the area have become obsolete now, and modern equipment and methods, while capable of measuring to very high precisions, cannot automatically give or tell the right boundaries and owners of land tracts established centuries ago. This paper examines the land boundaries situation in the study area, the impacts of mining on this, the need for boundary retracement surveys, the challenges that the rampant destruction of boundary markers in mining communities pose to such resurveys, and offers suggestions on dealing with these challenges in the management of land in the area. It also provides helpful information to land owners, land ‘buyers’ and land surveyors on the effects of the boundary problems on land transactions, surveys and registration in mining areas.

Abstract. This study investigates the feasibility of using low-cost consumer drones, specifically the DJI Mini 2, for land surveys compared to commercial-grade drones like the DJI Phantom 4 Pro V2. The research, conducted within the University of the Philippines - Diliman campus, evaluates the horizontal accuracy of resulting ortho-images and explores the advantages and disadvantages of each platform. Initiated by the recognition of aerial drones' transformative impact on land surveying, particularly acknowledged by the Land Management Bureau in the Philippines, the study addresses concerns about the use of consumer-grade drones for surveying. While some advocate for commercial-grade drones, citing concerns about accuracy, a prior study in India demonstrated the suitability of consumer-grade drones for geomatics applications. The methodology involves creating a flight plan with specified parameters for both drones, establishing Ground Control Points (GCPs), and conducting two flights. The results, processed using UAS Mapping Workflow, indicate comparable errors between the consumer-grade DJI Mini 2 and commercial-grade DJI Phantom 4 Pro V2. Despite slight differences, both drones meet the accuracy standards for land surveys. The study contributes to the discourse on affordable means of secure land tenure, envisioning consumer-grade drones as viable alternatives for cost-effective land surveys. The DJI Mini 2, at a fraction of the cost, demonstrates the capability to achieve accuracy levels comparable to its commercial counterpart. While acknowledging the need for further testing and optimization, the findings suggest the potential of consumer-grade drones in advancing sustainable urban development and poverty reduction through accessible land survey methods.

Abstract:

With the rapid growth of new surveying and mapping technology and surveying and mapping instruments, engineering surveying has also been developed rapidly. Land survey is a foundation for the country to effectively manage and plan land. When land is used, relevant information can be found in the database established in previous land surveys, so its accurate measurement method is particularly important. On the one hand, there are more and more land surveying work, and the surveying and mapping data of land surveying units are more accurate. On the other hand, with the increasing difficulty of land surveying, surveying units have put forward higher requirements for surveying and mapping technology. Under the background of the continuous growth of China's economy and society, the level of network information technology has improved rapidly, and digital information technology is widely used in land survey, which can improve the efficiency of land survey. This paper analyzes the application of digital mapping technology in land consolidation planning, hoping to provide some reference and suggestions for the smooth growth of land consolidation planning and the improvement of the accuracy of survey results.

AbstractThis research promotes our understanding of organic farmers' decisionmaking through individual farmers' experiences. A twofold survey was conducted to investigate characteristics of certified organic farmers in Colorado. Data from a mail survey (26 responses to 49 surveys sent) reveal patterns of farm operations and attitudes among this group of farmers. These questionnaires focused on land use, land tenure, operational change, and personal characteristics. In-depth interviews of five case study farmers provide additional insight into farmers' agricultural decisionmaking. These interviews were conversations that the farmers guided toward topics of relevance to them. Taken together, the mail and interview surveys provided information about on-farm operational factors and personal characteristics. Quantitative analysis and qualitative data reduction techniques were used to identify factors in organic farmer decisionmaking. The following eight factors help us understand organic agriculture in this region: diversity, challenge, change, businesslike approach, no formal agricultural education, love of the land, anti-”radical environmentalist,” and obstacles.

Abstract:

The Brazilian urbanization process produced a complex urban space, with a variety of urban land use and cover as a result. The study of these forms through a classification system is essential, but most current systems don’t capture this complexity, condensing it. Urban forms are difficult to distinguish and classify, resulting in the need for a system with a high degree of detail, for a more accurate urban planning. The objective of this work is to propose a classification system for urban land use and cover, which can demonstrate the multiplicities through remote sensing, using data from CBERS 04A satellite. The methodology surveys the visual elements of remote sensing images, through visual interpretation, relating them to each proposed use and cover class. With this, a classification system was developed that covers the urban space in 17 classes, being an effective way to raise information about the different urban forms.

Abstract:

Abstract Land rental markets are growing worldwide and facilitate efficient utilization of land. However, the short duration of occupancy and limited property rights mean that rental contracts may discourage longer-term sustainable land management. Direct investigation into the relationship between land tenure and ecological outcomes has been hampered by scale-appropriate data on land tenure, resource management, and land outcomes. In this paper, we address these issues with a study design that combines participatory mapping, household surveys, and remote sensing. We analyzed these data in a multilevel statistical model, controlling for environmental and land management influences. Our results show that rented land parcels are associated with worse rangeland outcomes compared to privately held parcels. This study contributes to the literature by documenting important empirical effects of rental markets and presenting a replicable workflow for integrating earth observations and micro-level survey data, which can be adopted by researchers and practitioners in regions where land registry data is unavailable or inaccessible. The results have important implications for incentive and compensatory-based environmental policy.

During the period 1953–69, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) conducted fourteen integrated land resource surveys in the Territory of Papua and New Guinea with the aim of identifying areas suitable for accelerated development. The resulting reconnaissance-level regional survey reports and maps provided extensive baseline information for national development planning. Related disciplinary publications expanded scientific knowledge of land resources and resource use in the wet tropics more generally. Substantial botanical collections carried out during the surveys contributed to building the Papua New Guinea (PNG) national collection at the Lae Herbarium and to the establishment of what is now the Australian National Herbarium.

Abstract:

Land subsidence is not a new phenomenon for Semarang the capital city of Central Java Province with recent population of about 1.5 million. Some report said the subsidence in Semarang probably is occurring for more than 100 years. Geodetic surveys such as GPS Surveys can detect land subsidence accurately. Land subsidence in Semarang exhibits spatial and temporal variations with the typical average rates of about 3 to 10 cm/year until recently it seem the acceleration existed in some region of the city. This acceleration will increase the risk of negative consequences from the land subsidence. This paper present and discuss the acceleration of land subsidence in Semarang as detected from GPS Surveys. The surveys have been conducted in 2008, 2009, 2010, 2012, 2016 and 2017. From 2008 to 2012 the subsidence generally follow linier rates while from 2012 to 2017 seem they are accelerating. The northern eastern region of Semarang along the coastal area still exhibits relatively higher rates of subsidence along with acceleration in rates compare to others region. Ground water exploitation is suspected to be the causes of that land subsidence phenomenon in Semarang city

Abstract:

Conventional approaches for urban land use land cover classification and quantification of land use changes have often relied on the ground surveys and urban censuses of urban surface properties. Advent of Remote Sensing technology supporting metric to centimetric spatial resolutions with simultaneous wide coverage, significantly reduced huge operational costs previously encountered using ground surveys. Weather, sensor’s spatial resolution and the complex compositions of urban areas comprising concrete, metallic, water, bare- and vegetation-covers, limits Remote Sensing ability to accurately discriminate urban features. The launch of Sentinel-1 Synthetic Aperture Radar, which operates at metric resolution and microwave frequencies evades the weather limitations and has been reported to accurately quantify urban compositions. This paper assessed the feasibility of Sentinel-1 SAR data for urban land use land cover classification by reviewing research papers that utilised these data. The review found that since 2014, 11 studies have specifically utilised the datasets.

Abstract:

Land price plays a crucial role in the development of a region, which serves as an indicator of the features of a property. The primary goal of this paper is to explore the relationship between land price and various geographical and accessibility parameters and thereby arrive at a model to predict the land price. Based on literature surveys, the parameters that influence land price are identified further through which data collection from primary surveys, the creation of a road network map, a geographic information system (GIS) analysis to determine the distance to the central business district (CBD), measurement of road density and access road width, assessment of employment opportunities through establishment surveys, and identification of various land use parcels in the study region are accomplished. The land prices are collected from recently sold parcels in each of the zones in the study region. A negative and significant correlation is observed between land price and distance to the CBD. Positive correlations are observed between land price and other factors considered, such as road density, availability of educational facilities, employment opportunities, and the extent of commercial and residential land use areas. A non-linear regression model is developed that can predict land price depending on the significant parameters.

Abstract:

Global Positional Systems (GPS) now is competing with traditional surveying techniques in almost all fields of geodesy and cadastral surveying after the availability of highly productive new systems such as Real Time Kinematic (RTK) systems along with the use of Global Navigation Satellite Systems (GNSS). Although the cadastral mapping of the entire Nepal was completed in 1996 using graphical survey with plane table technique, derived information from the existing maps now are outdated and do not fulfil the needs of the general public. Updating cadastral maps is not only necessary but vital in Nepal. Survey Department under the Ministry of Land Reforms & Management, Government of Nepal now has to adopt an appropriate innovative approach for cadastral mapping in the country in order to meet the growing public demands on reliable land information system, to provide speedy land administrative services as well as for overall development of the country. With continual research and development into GPS, the techniques and systems developed have become more reliable, cheaper and more productive, making GPS more attractive for a range of surveying solutions including cadastral mapping. Though high resources may be initially required for the RTK GPS technology for cadastral surveys in Nepal when compared to presently available optical surveying techniques, it would be justifiable in investing in GPS surveys. This technology, however, will not replace the existing survey techniques but it will provide another means in carrying out cadastral surveys especially in the area where the conventional technique is not economically and temporally viable.

Abstract:

Neglect of enclosed pasture is a familiar feature of farmland in Ireland, and this survey examines the distribution of neglected pasture fields in the Sperrin Mountains of Northern Ireland. Neglect was denned by invasions of heath species, rushes, sedges and mosses competing with cultivated grasses, and identified from Ordnance Survey Six Inch maps and two air photograph surveys. The distribution of neglected fields was related to the physical variables of altitude and aspect, as well as to the date of enclosure. Generally, neglected fields were more common at higher altitudes, north facing aspect and in land enclosed after 1833, but many exceptions were found. Neglect was also classified on a temporal scale by observed frequency of neglect at the several surveys of maps and air photographs, but it was considered that the many cultural reasons for neglect could be suggested rather than used as explanations.
