The topographic-cadastral measurements conducted in this study focus on all field and calculation operations necessary for representing the earth's surface on a plan or map, in a specific cartographic projection and at a designated topographic scale. The general cadastre is a unified and mandatory system for technical, economic, and legal records that identifies, registers, and describes all land areas on topographic maps and cadastral plans, regardless of use or ownership, across the entire country. This article aims to illustrate and test the proposed model, evaluating the data accuracy regarding predictive measurements for topographic surveys conducted in Crișeni, UAT Cridorolț, Satu Mare County. The area was analyzed using mobile scanning with the Leica Pegasus: Backpack equipment, combined with two GNSS devices, the Leica GS 14 and the Leica GS 08 Plus. In developing the general cadastre for this administrative-territorial unit, modern technology was also employed—specifically UAV technology, which enables high-accuracy surface measurements with reduced work time. The data collected from the flight were downloaded and subsequently post-processed using specialized software: Pix4D Mapper. The results obtained are stored in digital format, and after export, are saved as .dxf files, allowing access in either digital or analog form through the AutoCAD processing program. The generated orthophotoplan is exported in .ecw file format. Using the Leica Pegasus equipment, the data are stored digitally and subsequently undergo post-processing with the Pegasus Manager software, while the point cloud processing is carried out using Cyclone software. In this case, processing resulted in the delineation of property street fronts and existing structures on the terrain. GNSS equipment was used to perform detailed topographic measurements.
