Established and measured between 1816 and 1855, the Arc was instrumental in determining the Earth's size and shape by measuring triangulation arcs and astronomical coordinates. The survey was a model of international cooperation, involving both scientific and administrative collaboration [7]. The Struve Geodetic Arc include 258 main triangles with 265 main and over 60 subsidiary station points that passes through ten countries, i.e. Norway, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Belarus, Moldova and Ukraine. Each of the ten countries possesses some sites with reliable signs, which mark on the ground the positions of the geographical points where the measurements were performed [1][2][3]. The ten countries concerned have contributed to the preparation of the documentation with a view to nominating the Arc for inscription on the World Heritage List. The World Heritage Committee inscribed the Struve Geodetic Arc on World Heritage List in July 2005 [8]. The World Heritage site includes 34 commemorative plaques or built obelisks out of the original 265 main station points. According to the common procedures and guidelines based on the World Heritage Convention, each State Party is responsible to take care of the preservation and other management of the sites within its territory. The Struve Geodetic Arc is one of the foremost scientific and technical achievements of its time, and it has a truly universal significance. For almost 200 years the Arc has connected from the Black Sea to the Arctic Ocean and will continue connected also in the future. The paper describes the status of Struve Geodetic Arc and procedure of the national legislation, preservation and Management Mechanism and joint international responsibility of the countries possessing the Struve Geodetic Arc sites [4][5][7][9]. 2025-01-01T00:00:00Z https://repository.utm.md/handle/5014/33917 The use of orthophotos for cadastral works in the Republic of Moldova MEREACRE, Rodica; NISTOR-LOPATENCO, Livia The use of orthophotos in cadastral work is an important aspect of modern technology and geographic information systems used in the context of cadastral work. An orthophotomap can be used in a wide range of cadastral activities, including mapping and updating cadastral maps, determining property boundaries, land valuation, underlining their importance in modernizing and streamlining the processes of property registration and delimitation. 2025-01-01T00:00:00Z https://repository.utm.md/handle/5014/33916 Creating an interactive GIS-based map for the Technical University of Moldova campus using QGIS and web technologies CĂTĂRĂU, Nichita; ȘLEPAC, Vlada; VLASENCO, Ana This study details the process of developing an interactive map of the Technical University of Moldova campus using QGIS, an open-source GIS tool and the QGIS2Web plugin also some coding lines. This study involved gathering and structuring spatial data for campus buildings and other essential facilities, which were then visualized on an interactive map offering a clear and user-friendly representation of campus building locations. Pop-up windows were set up for each point of interest to show information such as building identifiers, available dormitories, working hours, contact information, and links to faculty webpages, ensuring users can easily retrieve relevant details. To make the map accessible online, the research utilized the Leaflet JavaScript library, which facilitated adding interactive features and integrating the map on a local server. The final map presents a simple and intuitive interface, allowing users to explore the campus, find specific locations, and access necessary information quickly. This project highlights the potential of open-source GIS tools as an effective and accessible method for mapping university campuses, aiding in spatial orientation and streamlining information access. The interactive map created can serve as a reference for other universities wishing to develop similar systems, showcasing how GIS and web technologies can enhance the user experience in academic environments. 2025-01-01T00:00:00Z https://repository.utm.md/handle/5014/33911 The Bonne pseudo-conic projection for the territory of the Republic of Moldova HROLOVICI, Alexandra; DRUGUȘ, Daniil; VLASENCO, Ana The paper presents a study on the equivalent pseudo-conic Bonne map projection for the representation of the territory of the Republic of Moldova and the associated cartographic grid, providing a rigorous and efficient mathematical method for calculating point positions within this projection. The primary aim of the study is to ensure increased accuracy of cartographic data and to minimize specific deformation errors, such as linear and angular distortions, which may occur during the process of depicting the Earth's surface on maps. The article delves into the methodological details of the calculations involved in applying the Bonne projection, focusing on the analysis of geometric errors and identifying the most effective techniques for determining these errors. Additionally, it offers a comprehensive approach to the process of automating calculations by developing specialized algorithms implemented using modern programming languages. These algorithms are capable of generating precise results, which can subsequently be exported in formats compatible with CAD or GIS systems, facilitating their integration into professional cartographic workflows. Another aspect of the paper is the graphical analysis of the territory of the Republic of Moldova in the Bonne projection. The graphical representation was carried out using AutoCAD software, highlighting both the advantages and limitations of this projection, with a precise indication of the deformations encountered. The paper emphasizes the importance of algorithmizing the calculation process as part of modernizing the geospatial infrastructure, underlining the relevance of using an equivalent projection to achieve a faithful representation of the Earth's surface. 2025-01-01T00:00:00Z
