For the purposes of this paper, the measurements were taken in the unincorporated area ofTimisoara. Their aim is to make an inventory of the lands belonging to Banat University of AgriculturalScience and Veterinary Medicine (USAMVB) Timisoara, Timiş County. The parcels included in theinventory belong to the Public Domain of the Romanian State and are managed by BUASVM Timisoarafor the Teaching Experimental Station, in compliance with Government Decision 2066/2004, no3001/2006. The following parcels are included: A347, A354/1, A359, A369, Cc372, A373/1, A375/5,A398, LL417/1, VN422, VN424, LL472, A519/1 and A521/1/1. The topographic survey perimeter isdelimited by Berecsau in the north, Hpr 337, Timişoara-Arad National Road (DN) 355 in the east, thebuilt-up area of BUASVMT in the south and Calea Torontalului-Cenad National Road (DN) 525 in thewest. For the purposes of the present paper, the surveys were performed using Leica GPS 1200, a state-of-the-art device that uses SmartWorx v8.10 technology and a Bluetooth connection. The GPS referencesystem is WGS 84 (World Geodetic System 1984) that, like the ITRF system, is defined by the coordinatesof the determined terrestrial points. The wider and wider use of satellite positioning systems and satelliteglobal mapping systems for geodetic operations may cause serious practical difficulties if the results ofthese spatial techniques must be related to older maps or digital data. The main difficulty lies in changingdata from geocentric datums to local datums that describe older data or viceversa. Data resulting frommeasurements are stored on a Compact Flash card. The data in the device is downloaded with theCompact Flash card that will be connected to a card reader and with the Leica Geo Office Combinedsoftware, which is easy to use both for downloading and loading data in the device. The WGS84coordinates were transformed into 1970 stereographic coordinates using TransDat 4.0. The 1970stereographic coordinates were transferred to AutoCad to draft this topographic work.
