Updating and digitizing cadastral maps remains a major challenge in land administration, demanding significant financial and human resources. This study presents a fully automated AI-based system to address this issue, focusing on the extraction and digitization of agricultural cadastral maps using photogrammetric images. The proposed method leverages the segment anything model for high-accuracy segmentation, achieving a notable intersection over union score of 92%, significantly outperforming traditional approaches. In addition, the system reduces processing time by 40% and eliminates the need for manual intervention, enabling scalable, efficient digitization. These improvements are critical for better land-use planning, resource allocation, and sustainable land management practices. The model, implemented using open-source Python libraries, integrates three stages: image preprocessing, AI-based segmentation, and postprocessing. By automating these processes, the system not only accelerates map production but also reduces environmental impacts associated with traditional mapping techniques. The approach also enhances the accuracy of agricultural boundary delineation, offering benefits for land dispute resolution and optimized agricultural practices. This research contributes to the modernization of land administration systems by providing an accessible, scalable solution for surveyors and policymakers. It bridges the gap between cutting-edge artificial intelligence advancements and practical applications, addressing technical and operational challenges in geospatial data management. The findings underscore the importance of automating cadastral mapping for both economic efficiency and environmental sustainability.
This study investigates the use of unmanned aerial vehicles (UAVs) for geodetic surveys aimed at updating cadastral registers, which now function as geospatial databases. UAVs, using the aerial photogrammetric method, offer a cost-effective and efficient alternative to traditional airplane-mounted cameras. The research presents a comprehensive, step-by-step procedure for creating cadastral maps using UAV-acquired data, covering scope definition, preparatory work, flight planning, data processing, and final map production. The study includes an analysis of the resulting cadastral map and compares it with existing official maps to assess accuracy in determining parcel boundaries. The findings demonstrate that UAV-based surveys not only streamline the mapping process but also provide high levels of accuracy and reliability. This approach showcases the potential of UAV technology in modernizing cadaster systems, offering valuable insights into improving the precision and efficiency of geospatial data collection for land management and planning.
The systematic approach to the establishment of a cadaster in most European countries has resulted in a variety of cadastral documents. Most official cadastral data are from the 19th and 20th centuries and are stored as hard copies or electronic data in a data warehouse, while the original documents are stored in analog format in separate locations, making the cadastral data difficult to access. The increasing interest in the use of archival cadastral documents has stimulated their digitalization in most countries, allowing users to access cadastral documents through metadata catalogs. Most catalogs use archival metadata standards to describe cadastral documents, with a lack of application of geoinformation metadata standards that represent fundamental spatial datasets. Archival metadata standards do not provide enough information about the origin and quality of cadastral data. The aim of this study was to examine the applicability of the ISO 19115-1 standard for describing cadastral documents. The methodology includes a comparison and an analysis of documents which are stored in different locations. The metadata of archived cadastral documents are recorded in archive inventories, and archives use different terminology for documents with the same content. The scientific contribution of this study is given by the classification of key documents and their associated properties that uniquely described each document. Four types of documents were classified by comparison, and we analyzed the content between documents. Property identification resulted in the semantic mapping to metadata elements of ISO 19115-1 and showed a considerable congruence of elements. It was possible to apply the ISO 19115-1 standard for describing documents of systematic cadaster establishment, with additional extensions for some elements. Proposed extensions to describe the cadastral documents include replacing free text with domains of appropriate values, adding stricter obligations, and restricting the use of domain values. The standardization of metadata for analog cadastral documents in archives has created a prerequisite for the development of a metadata catalog, which would increase the availability and accessibility of cadastral data for different user groups.
Recently, remotely sensed data obtained via laser technology has gained great importance due to its wide use in several fields, especially in 3D urban modeling. In fact, 3D city models in urban environments are efficiently employed in many fields, such as military operations, emergency management, building and height mapping, cadastral data upgrading, monitoring of changes as well as virtual reality. These applications are essentially composed of models of structures, urban elements, ground surface and vegetation. This paper presents a workflow for modeling the structure of buildings by using laser-scanned data (LiDAR) and multi-spectral images in order to develop a 3D web service for a smart city concept. Optical vertical photography is generally utilized to extract building class, while LiDAR data is used as a source of information to create the structure of the 3D building. The building reconstruction process presented in this study can be divided into four main stages: building LiDAR points extraction, piecewise horizontal roof clustering, boundaries extraction and 3D geometric modeling. Finally, an architecture for a 3D smart service based on the CityGML interchange format is proposed.

The idea behind the Infrastructure for Spatial Information in Europe (INSPIRE) project was to provide EU citizens with access to various types of information, including environmental protection and spatial management data. These resources can be viewed (Web Map Service—WMS) and downloaded (Web Feature Service—WFS) online. Cadastral datasets represent one of the 34 spatial data themes in the spatial data infrastructure (SDI). The functionality of the SDI has not yet been fully achieved due to the failure of the WMS and WFS network services. The aim of this article was to assess the completeness of the SDI containing cadastral datasets. The present study has practical implications. The proposed diagnostic tool supports an assessment of the completeness of SDI resources in seven diagnostic groups (technical and legal identifiers, the cadastral information profile, the WMS network service, the WFS network service, source cadastral databases, data validity, and WMS and WFS standardization). The developed assessment methodology enables the identification of websites that publish cadastral data through INSPIRE network services, as well as problematic websites, and it has high development potential. The results of the assessment should be used in the ongoing construction of the SDI. They can also be used to improve the quality of network services and their availability for end users.

improve long-term structural monitoring, contributing to reduce potential risk of damages or failures.
Collecting and sharing monitoring data through an IoT infrastructure ensures a constant and secure access to the information by professional users' networks that are often urged to take decisions and activate further investigations. By implementing such integrated systems, a more effective and widespread monitoring of existing building stocks can be achieved
The normative legal acts and scientific publications on the distribution (redistribution) of land by purpose and types of use are analyzed on the example of land uses of institutions and enterprises of the National Academy of Agrarian Sciences of Ukraine (hereinafter - NAAS). It is established that in the current legislation there is no type of documentation on land management, concerning the decision of questions of distribution (redistribution) of land by types of use. To take into account the specifics of land use by the NAAS institutions and enterprises, which have land plots, research fields, nurseries, valuable lands for scientific research, which should be taken into account when developing documentation on land management.
The necessity of introducing scientific justification for determining the purpose and type of use as a section in the land documentation documentation is proposed.
The theoretical and methodological principles of the process of formation of the institutional environment of ecological safety of vital activity of the population at the local level have been determined.

After having successfully sailed the Northwest Passage in 2012 with the first fully Italian expedition, Best Explorer, a 51 feet steel recreational sailing yacht, will complete the circumnavigation of the Arctic Ocean in 2018, from Japan to Norway, sailing north of the Eurasian continent (Siberia), from the Pacific to the Atlantic Ocean.
The Northern Arctic Sea Route – NASR is an extremely long and challenging route: 8,500 nautical miles, most of which (4,500 n.m.) in the Arctic Ocean.
The Team, on board and on shore, is composed by all members of “Arctic Sail Expeditions – ITALIA” association and Giovanni (Nanni) Acquarone, the skipper and expedition leader, is one of Italian guys having had an extensive knowledge of the Arctic, having sailed the most difficult sea courses of the world, even more in the legendary Northwest Passage.
This is a project that will bring Italy’s name to the attention of the public once more and, if properly supported and advertised, will be an incentive for many to valiantly start other similarly outstanding feats.
Cultural and scientific projects will be carried out in parallel with the expedition, such as meetings with local communities or experimentation of satellite technologies (positioning such as GPS and Galileo, telecommunications and Earth observation), depending on partners or sponsor requirements.
Infrastructures and surrounding areas can present great risks where structural movement or failure of infrastructure can result in catastrophic consequences also for the people living and working in nearby existing buildings, besides for the teams of workers involved in the infrastructures underway. As a positive and important consequence of this growing awareness, the increasing application of systematic techniques for structural monitoring has proved essential for risk comprehension and management throughout the entire life cycle of infrastructures.
In this article reference is made to the remarkable investments that the UK has been lately pledging (wishing similar measures are taken also in our country), both for the improving of existing aging infrastructures
and for new projects.

The article discusses contemporary issues of digital atlas thematic mapping, which has been gaining momentum in recent decades. It shows that the atlas geoenvironmental mapping allows to perform high quality visualization of various spatial and temporal information in dynamic and static states, reflects the geoenvironmental state of objects that vary by rank, trends in its changes, and evaluates the influence of natural and anthropogenic factors on it.
Solution to this problem is possible with the correct choice of cartographic service, which can serve as the basis for creating a wide range of interactive digital atlases. Using the ArcGIS Online service allows you to use a larger range of cartographic imagery, which attracts users. At the same time, there are few examples of the creation of atlases of geoenvironmental issues both in paper and in digital form, so the article discusses actual problems in this area.
The views of various scientists on the nature of geoenvironmental atlas are characterized. It is shown that atlases of geoenvironmental content should have in their structure basic maps of such subjects: physical geography (hypsometric, geological, tectonic, hydrogeological, geomorphological, soil, hydrological, meteorological, biogeographical, etc.); Socio-economic (demographic, labor resource potential, health, industry, agrogeography, forestry, water management, mining, recreation and tourism, etc.); Ecological (ecology-geomorphological, ecology-geological, hydroecological, soil-ecological, bioecological, landscape-ecological, air pollution, medical-ecological, sanitary-epidemiological, etc.); Applied maps (recommendations aimed at solving geoenvironmental problems, optimizing the use of natural resources and improving living conditions of the population and biota).
The article considers the options of atlases classifications and thematic maps that are part of their composition, offered by domestic and foreign authors. The range of problems and tasks connected with the development of digital atlas geoenvironmental mapping of diverse geospatial objects, in particular river-basin systems, is outlined. The ways of solving the problem of information provision of geoenvironmental mapping of the territory of Ukraine are proposed.
Over the past decade, land-based laser scanning technologies have been actively studied and implemented, in response to the need for detailed three-dimensional (3D) data about our rural and urban environment for topographic mapping, cadastral mapping, and other street-level features, which are difficult and time consuming to measure by other instruments. For rural areas in China, the complex terrain and poor planning limit the applicability of this advanced technology. To improve the efficiency of rural surveys, we present two SSW (Shoushi and SiWei) laser scanning systems for rapid topographic mapping: stop-and-go and electro-tricycle laser scanning systems. The objective of this paper is to evaluate whether laser scanning data collected by the developed SSW systems meet the accuracy requirements for rural homestead mapping. We investigated the performance of the two laser scanning systems on Ma’anshan Village, a small, typical village in Hubei Province, China. To obtain full coverage of the village, we fused the stop-and-go and electro-tricycle laser scanning data. The performance of the developed SSW systems is described by the results of building contours extracted from the fused data against the established building vector map.
