The studies presented in this paper were carried out in the western part of Romania, on the administrative territory of Deva Municipality, in the Vulcan area, in order to achieve a zonal urban plan. The purpose of the study is the acquisition of GIS data related to the realization of the plans for the technical approval for the Vulcan zonal urban plan. To achieve this plan, by default a GIS database, we used the LEICA TS02 total station with the measurement accuracy of 1 mm / km for distances and 2 seconds for angles, GNSS GPS rover RTK South S82T equipment to determine the points marked on the route that is to be traversed by the eBee senseFly drone, which helped with time management. Regarding the detailed topographic surveys, made with the help of GNSS equipment, total and aerial photography stations, the use of aerial photography technology is a real advantage, by reducing the working time, the investigated area and the complexity of the acquired data. The accuracy of these measurements is up to par with that from the usual equipment used. The advantages of using geographical information systems and their applicability in many fields has led to the spread of this concept. Most institutions, companies working with spatial data have initiated a GIS project. Once all the information from the field is collected, the office part follows, where all the collected information is gathered and a plan is made in AutoCad, respecting the layer levels. At the same time, the data taken with the aircraft is downloaded, thus making an orthophotoplan. The orthophotoplan is aligned on the points taken over with the GNSS equipment or the total station, during the measurements. After making this plan, it is loaded into AutoCAD to complete the database with information on postal numbers, street name, green areas in that area, street width. Some information will be retrieved automatically, but other will be entered manually for each entity. This working method offers a short working time while not compromising data accuracy.
