ABSTRACT
The Banat’s University of Agricultural Sciences and Veterinary Medicine „King Michael I of Romania” from Timisoara is located in the Banat’s Plain, in the western part of the country, and is 70 years old. Topographic survey was carried out in the University’s Campus aiming at drawing a situation plan of the faculties of Animal Husbandry and of Veterinary Medicine using routes supported at both ends by known coordinates and a TopoSys soft to compensate the survey. Topographic survey was carried out with a Leica TC 805 total station and the support points used were GPS-determined with a Leica Geo Office Combined Programme; the resulting files were transformed with DXF Generate, after which the points were reported in AutoCad with a TopoLT Programme. To carry out the survey, we used eight old known coordinate points that we determined with a Leica GPS equipment, system 1200, and WGS 1984 coordinates were transformed with a TransDat programme into Stereographic 1970 coordinates. Coordinates were determined in the Stereographic 1970 projection system and point quotas were determined in relation to the Black Sea level. Reduced observation compensation is done with the Smallest Square Method with correction equations developed through the indirect method. To filer greater errors, we sued the robust (Danish) method and the TAU test to determine the thrust threshold.
