Abstract


The purpose of this paper is to obtain thematic maps and topographic analyzes determined on the field and processed through the basic programs of AutoCAD, TopoLT and Global Mapper which along with topogeodezical details high up in on the field create a database required to implement a feasibility study, as a previous step of the general cadastre in the Farcasesti village, Gorj county.

Topographical surveying were made with GNSS technology using the RTK-Kinematic method, South V-82 type in Real Time  and data processing was performed by specialized graphics programs.

Field data collected with GPS RTK were transferred to a computer using specialized software LeicaGeo Combined Office and other software like Notepad, Excel, Word, AutoCad 2013. The imported data from the field in three spatial coordinates, respectively X, Y and Z, were the basis for drawing up planimetric situation plans by outlining the details of the terrain and elevation.

In the present paper, we demonstrate that the use of GPS technology made possible topogeodezical data collection from a large area with high precision in a short time using reduced material and human resources. This allowed us to import data from the field by using topogeodezical specialized programs and accurately achieve the outlines of buildings and perimeter, as verified by superimposing them on orthophotomap. Achieving digital plans using AutoCAD Architectural demonstrated that they can be made with accuracy and precision permitting various analyzes of land, including the construction of contour in 2D and 3D.
