Geodetic Support for the Use of Natural Resources of Chernivtsi Region Using GIS

Maps and plans are necessary to obtain accurate spatial information about the location of any geo-objects. High-quality and accurate creation of cartographic materials will improve the assessment of natural resources, cadastral work, etc. to solve the problem, cadastral maps and plans of a given scale are necessary. Their creation without violating regulatory documents requires certain State Geodetic Network (SGN) points. The purpose of the study is to analyse the spatial location of SGN points on the territory of the Chernivtsi region in Ukraine and to assess geodetic support for the use of natural resources using geographic information systems (GIS). We used QGIS version 3.28, to create maps and models based on the thematic layers, and evaluated the existing geodetic support in the section of the newly created administrative and territorial units of the region. An assessment of the spatial placement of SGN points for the territory of the Chernivtsi region by the administrative-territorial division was carried out. We identified 198 geodetic points of different classes. The boundaries of Chernivtsi district had the largest number of geodetic points (109 units, which is 55% of the total region). This was followed by Dnistrovsky District (54 points - 27% of the region), and Vyzhnytsky District (35 objects - 18% of the region).
