The topographic operations for this paper were performed at Farm No 5 of the Didactic Station of the University of Agricultural Sciences and Veterinary Medicine Timisoara. The Leica TPC 805 Total Station was used for the topographic and land survey measurements, and the data were downloaded with LEICA Geo Office Tools special software. Class V points within the university were used for the measurements. These points were determined with a planimetric traverse, starting from station point A1, where a retrosection was applied, to station point A7, where a resection method was applied to close the traverse. A planimetric traverse was performed to make the support network denser at station points A1 and A8, from which a resection method was applied to close the traverse. The total station is an optical device used for topographic measurements. It is a combination of the classic theodolite and an electronic instrument for measuring distances. The total station can include a small computer that provides storage capacity and makes precise calculations. The following plans were executed after the measurements were taken: site plan 1:500; plot plan 1:1000; development site plan 1:10000. Generally, a geodesic network has at least two old (already coordinated) points that in the first stage help determine the coordinates of the “new” points with the help of a certain method.  A direct link is created between the older points through horizontal angular observations. Distances and orientation must also be determined between these points. These elements will be used in the compensation calculations. For this reason, their determination must be very precise. The calculations of the geo-topographic support networks were done with the TOTAL 2.0 software. The (temporary) coordinates of the points to be determined are done automatically. The compensation of the support network is done with the least squares method, the indirect measurement method. The software creates a DFX file that can be used with the AutoCAD package at a later time. TOTAL 2.0 calculates and, where necessary, compensates any combination of direction and distance measurements, from the easiest (cancellation of registration, multiple intersection, multiple resection) to the most complex ones (various traverses, polygonometric networks, triangulation).
