Academic literature on the topic 'Creation of digitalized cadastral map'

In conducting land boundary verification surveys in digitalized cadastral areas in Taiwan, possible parcel points must be surveyed. These points are employed in the overlap analysis and map registration of possible parcel points and digitalized cadastral maps to identify the coordinates of parcel points. Based on the computed horizontal distance and angle between control points and parcel points, parcels are staked out using ground surveys. Most studies survey possible parcel points using ground surveys with, for example, total stations. Compared with ground surveys, UAV (Unmanned Aerial Vehicle) aerial photogrammetry can provide more possible parcel points. Thus, an overlap analysis of digitalized cadastral maps, combined with the collection of possible parcel points, will be more comprehensive. In this study, a high-quality-medium format camera, with a 55 mm focal length, was carried on a rotary UAV to take images, with a 3 cm ground sampling distance (GSD), flying 300 m above the ground. The images were taken with an 80% end-lap and side-lap to increase the visibility of the terrain details for stereo-mapping. According to the test conducted in this study, UAV aerial photogrammetry can accurately provide supplementary control points and assist in the boundary verification of digitalized cadastral areas in Taiwan.

Abstract Health-related information is increasingly being collected and stored digitally. These data, either structured or unstructured, are becoming the ubiquitous assets that might enable us to comprehensively map out a patient’s health journey from an asymptomatic state of wellness to disease onset and its trajectory. These new data could provide rich real-world evidence for better clinical care and research, if they can be accessed, linked and analyzed—all of which are possible. In this review, these opportunities will be explored through a case vignette of a patient with OA, followed by discussion on how this digitalized real-world evidence could best be utilized, as well as the challenges of data access, quality and maintaining public trust.

Improvement of the land cadastre information system in the administrative district will make more efficient use of the land fund. More than 42,000 land users in Kibray, which is the object of the research, can quickly manage land resources through the creation of land information systems. As a result, the use of specialized software at the district level increases the quality of the specialists’ work compared to traditional methods, and time consuming 3 and 5 times the amount of data transmission to consumers. The collected and regulated data will serve as the main source of the unified system of land registration in Kibray district and the creation of a special land fund and its rational distribution among land users. The method developed to compile a digital cadastre map based on an example of an administrative district is the basis for the registration of land parcel and, in turn, the land fund distribution. Information on the state of land resources is mainly collected in the State Land Cadastre. Registration of the rights to the land parcel, the main component of which is the re-registration of new land users and the existing ones, requires the most up-to-date information on the land cadastre.

Purpose. The application of geodetic measuring systems and geodetic software in creating a planned geodetic basis for establishing the boundaries of the settlement or expanding its boundaries requires a modern cartographic basis in digital form and created a master plan. Methodology. This is achieved through geodetic measurements and computer processing of their results. GIS technologies and remote sensing in this case help to solve the problem quickly, accurately, efficiently and with the least time and money. Old cartographic materials, according to which geodetic surveys were carried out and which served as a basis for obsolete, do not meet modern requirements for the creation of cartographic products. Therefore, there is a need to update cartographic materials in new digital formats and enter in the created database of the State Land and Urban Cadastre, ie to fill the state cadastral system with information layers. The created information layers of the Public cadastral map and the Digitals software simplify the solution of problems of geodesy, cartography and land management. Entering information into the databases of the State Geocadastre and Urban Cadastre requires the creation of modern digital cartographic materials and electronic documents. DBNs adopted in Ukraine dictate certain requirements for the creation and design of appropriate cartographic materials for the development of Master Plans of settlements. Results. Geodetic surveys were performed on the research territory by electronic measuring systems and the results of measurements in the software were processed. The constructed plan-height substantiation of the territory of the settlement made it possible to create a digital map (model) of the area – CMM in a very short time. Scientific novelty. Such Digital maps are the basis for the creation of various cartographic materials in electronic form and can serve various purposes of the national economy. Such digital maps with the help of GIS technologies can be the filling of electronic resources of different industries and serve to fill different types of information about certain objects, phenomena, ie to monitor the land. Practical significance. The result of the study was the creation of a digital map of the settlement and entry in the databases of the State Land and Urban Cadastre information about the boundaries and structure by developing appropriate urban and land management documentation.

Landslides and rock falls are among the many phenomena that have an impact on sustainable construction and infrastructure safety. The main causes of landslides are natural meteorological and hydrological phenomena. In building design and construction, environmental monitoring by identifying geotechnical hazards must be taken into account, as appropriate hazard assessment contributes to ensuring future construction safety. The Carpathian region in southern Poland is particularly predisposed to landslide formation. This may be favored by the nature of the shapes associated with the high and steep slopes of the region’s valleys. Another reason for concern is the flysch geological structure, which is characterized by alternating layers of water-permeable sandstones and poorly permeable shales, clays, and marls. Furthermore, the presence of a quaternary weathering cover makes the geological structure more susceptible to landslide processes and tectonic formations. The paper presents the results of a study whose aim was to elaborate a detailed landslide hazard map for a selected area in the Polish Carpathians, using statistical methods. The approach is based on the Hellwig method, which seems particularly useful in the assessment of susceptibility and landslide hazards on a local scale for a relatively small area. A two-stage study was conducted. The first stage of the research involved the creation of a database associated with environmental parameters and triggering factors, whereas the second stage consisted of the adoption of weights for seven thematic sections and their special features on the basis of expert knowledge. The hazard map developed as a result was compared to the mapping made using the weight-of-evidence method. The proposed data normalization method allows the use and analysis of both qualitative and quantitative data collected from various sources. The advantage of this method is the simple calculation procedure. A large-scale (1:2000) map might be used to assess the landslide hazard for specific cadastral units. Such a map becomes the basis for municipal spatial planning and may be able to influence investment decisions. Detailed landslide hazard maps are crucial for more precise risk evaluation for specific cadastral units. This, in turn, allows one to reduce serious economic and social losses, which might be the future results of landslides.

Currently the official land parcel map of Uruguay does not allow a suitable interoperability with other available geographic information. We are considering using a national high accuracy and high resolution orthomosaic in two ways: either to support the creation of a brand new land parcel map or to allow amending the existing one. In particular, the present work is part of a set of experiments which considers different techniques to amend the existing land parcel map. In order to perform a fair comparison it is necessary to have test cases produced with a reference procedure properly and objectively evaluated. The metric of success will be used as attainable goal for any other alternative. Using the orthomosaic in order to identify the apparent limits of parcels in the land parcel map we were able to modify its location, thus making the map interoperable with the image. In order to measure the accuracy of the fit, we used the relative difference between the area declared at the parcel map (taken as the reference value) respect to the one computed from the GIS. We found that the discrepancy between the areas computed from the initial and the final dataset w.r.t. the declared area decreases, but not up to expected level. Once filtered for outliers the remaining discrepancies follow a normal distribution, where its bias and standard deviation varies from (-0.65%, 11.24%) before editing to (‑1.72%, 8.59%) later. Despite the drastic change in planimetric accuracy the improvement of the area accuracy is marginal. Considering the admissibility criteria of the Uruguayan National Cadastral Office, for the legacy dataset only 39.4% parcel maps could be accepted, a value which improves up to 49.7% after the manual edition. It is still far from the goal of 100%, and the reasons for such pessimistic finding will be discussed.

In Uzbekistan, more than half of population lives in rural area, their well-being depends on quality of land and water resources availability. Quality of land is determined by ameliorative indicators: ground water depth level, ground water salt amount and salinity of soil. These factors do not appear naturally but rather due to the human activity. Inefficient irrigation and excessive consumption of irrigation water on irrigated land in Boyavut District of Syrdarya region of Uzbekistan within several decades have led to a salinization of soil. The primary objective of this article is determination of the level of salinity of soil for modelling spatial distribution of soil salinity throughout an irrigated land by using GIS technology. This technology is focused on automation of development and creation of ameliorative maps, while totally eliminating manual operations. Nowadays, ameliorative expedition specialists still create cadastral map using tracing paper over the marginal areas within irrigated lands based on their ameliorative conditions and by selecting from the three thematic maps and then selecting the poorest conditions of ameliorative indicators. The suggested technology is designed for professionals of cadastral subdivisions of regional ameliorative expeditions, who use the GIS-based software, such as ArcView 3.2. or ArcGIS 10x; their duties include creating of thematic maps based on salinity levels of irrigated lands. Exact coordinates of collection sites of soils samples (collected in 2018-2019) were determined using GPS. The Inverse Distance Weighting (IDW) interpolation method was applied to use that data to create ameliorative maps categorized by the salinity levels (non-saline, slightly saline, saline area and highly saline areas). Those maps were then analysed to develop procedures on how to improve ameliorative conditions of irrigated areas.

<p><strong>Abstract.</strong> Even though planning process particularly economic development plan and its implementation in Nepal has been initiated with first five-year plan in 1952/54, land resource planning was overshadowed and only regional level data base on land use, land system and land capability were produced by Land Resource Mapping Project in 1983/84 and made available for planners and decision makers for sectoral planning in regional scale. During past, different policies and national planning efforts were made for balanced use of country’s existing natural resources but Nepal has not practiced land-use planning for the country as a whole at local level. It is initiated only after ninth five year plan (1997–2002) with the establishment of National Land Use Project under Ministry of Land Reform and Management and formulation of National Land Use Policy 2013 and its revision in 2015 after devastating earthquake. Land use council, Land use technical committee, District level land use monitoring committee and VDC/municipality level land use committee are institutional set ups for implementing planning works done by National Land Use Project at district and local levels. Resource maps produced by different international agency associated with India, Canada, USA, Japan and Finland were worked as basis for formulation of local level land use plans. Presently National Land Use Project (NLUP) has prepared land resources maps, geo-database and reports covering almost half of total VDCs of the country moreover in Terai region. Seven components of land resources management required for local level land use planning are present land use map, soil map, land capability map, hazard risk map, land use zoning map, cadastral superimpose on land use zoning map along with its geo-database and report except VDC profile. In first time, geospatial technology-RS, GIS and GPS were extensively applied in preparation of all these resource maps and creation of their geo-database for local level land use planning.</p>

Along with the folk crafts of the Transcarpathian region, an industrial tour is being developed in conjunction with industrial and natural objects that make up its resource potential. In the context of reforming economic relations, the emphasis is on the development of priority economic sectors – the forest and wood industry, light and food industries, the development of cross-border cooperation, recreation and tourism, etc. The main attention is paid to the further restructuring of the entire national economic complex, the involvement of domestic and foreign investments in the economy, the development of small and medium-sized businesses, and the effective use of natural resource potential. It is proved that the condition of full awareness of tourists is the creation of a passport of an industrial tour, which includes ecological, technical, and cadastral. Tours on mines from salt mining, precious metals, sulfur mines, oil wells, mineral water, ozocerite, objects of the former military complex – rocket mines, storage facilities, warehouses, enterprises for processing raw materials and materials, folk crafts are promising the direction of development of industrial tourism in Transcarpathia. Industrial tourism, as part of the overall tourist process in Ukraine, can be directed at solving many socio-economic tasks of local communities, the most important among them is increase of employment, growth of its welfare, provision of socio-cultural development of the region and improvement of quality of life of people. Today, in order to increase the competitiveness of the region in the tourism industry, the cluster method, which was previously used only in industrial production, is used. A tourist cluster [5] is a key organizational framework that combines tourism and other related industries into a single system that enables the enterprises, institutions and organizations to meet the priority objectives and enhance the competitive advantages of the region. By creating such an association, financing and implementation of even very ambitious projects in the tourism sector could be provided, which would otherwise be impossible for each individual participant. The developed map of the territorial placement of centers of industrial tourism in the Transcarpathian region greatly simplifies the creation of an informative cadastral system and on its basis industrial tours. At the same time, the improvement of this system requires the systematic introduction of new information indicators, taking into account the change in structural and functional relationships between different departments. In general, Transcarpathia has an all-Ukrainian significance in the economic plan as a region with significant potential of the forest and wood industry, winemaking, vegetable growing, dairy industry, tobacco production, mineral waters.

В статье приведены результаты анализа работ отечественных авторов, посвященных оценке экономического и социального ущерба, наносимого опасными гидрологическими явлениями (наводнениями). Все методики носят рекомендательный характер. Авторами принимаются во внимание различные факторы, влияющие на размер ущерба. Использование различных критериев, составляющих ущерб, приводит к получению разных цифр. Большинство методик не являются комплексными, не учитывают региональную специфику. Чаще всего определяется только реальный или прогнозный прямой ущерб, в то время как косвенный ущерб не рассчитывается. Преобладают оценки экономического ущерба в связи с ориентацией статистики на учет материальных ценностей. Социальный ущерб от наводнений оценить сложнее. Однако ущерб здоровью пострадавших от наводнений людей представляет не меньшую проблему, чем ущерб экономики. В статье отмечается, что для минимизации негативного воздействия, наносимого опасными гидрологическими явлениями (наводнениями), чрезвычайно важным является определение территорий потенциально подверженных риску наводнений. Выделено три этапа. На первом этапе требуется создание банка гидрометеорологических данных (превышение опасной отметки уровня воды и случаи затопления близлежащего населённого пункта, максимальные уровни, расходы воды, водного режима). На втором этапе производятся гидрологические расчеты, определяются уровни и расходы воды разной процентной обеспеченности. На третьем этапе на основе данных дистанционного зондирования земли строится цифровой рельеф исследуемой территории, изолинии рельефа нужной детальности, карта зон затопления (на основе рассчитанных уровня и расхода воды разной процентной обеспеченности), определяются площади затопления при 1 и 10 обеспеченности. Завершающим шагом является добавление таких данных Публичной кадастровой карты, как площадь земельного участка, его кадастровая стоимость и вид разрешенного использования. Используя нормативы укрупненных удельных показателей стоимости прямого ущерба в расчете на 1 га затопляемой площади населенных пунктов, возможно рассчитать прогнозный экономический ущерб. Для расчета прогнозного социального ущерба потребуются данные численности населения, проживающего в прогнозируемых зонах затопления, его половозрастной состав, занятость.The article presents the results of an analysis of the works of domestic authors on the assessment of economic and social damage caused by dangerous hydrological phenomena (floods). All methods are advisory in nature. The authors take into account various factors affecting the amount of damage. The use of various criteria constituting the damage leads to different numbers. Most of the methods are not complex, do not take into account regional specifics. Most often, only real or forecast direct damage is determined, while indirect damage is not calculated. Estimates of economic damage prevail in connection with the orientation of statistics on accounting for material values. Social damage from floods is more difficult to assess. However, the damage to the health of people affected by floods is no less a problem than damage to the economy. The article notes that in order to minimize the negative impact caused by hazardous hydrological events (floods), it is extremely important to identify areas that are potentially at risk of floods. Three stages are distinguished. At the first stage, the creation of a hydrometeorological data bank is required (excess of a dangerous water level mark and cases of flooding of a nearby settlement, maximum levels, water discharge, water regime). At the second stage, hydrological calculations are made, the levels and discharges of water of different interest rates are determined. At the third stage, based on the data of remote sensing of the earth, a digital topography of the study area, contour contours of the required detail, a map of flood zones (based on the calculated level and flow rate of water with different percentage coverage) are built, and the flood areas are determined at 1 and 10 coverage. The final step is to add such data of the Public Cadastral Map as the area of the land plot, its cadastral value and type of permitted use. Using the standards of aggregated specific indicators of the cost of direct damage per 1 ha of flooded area of settlements, it is possible to calculate the predicted economic damage. To calculate the predicted social damage, you will need data on the number of people living in the forecasted flood zones, their gender and age composition, and employment.
