Studies shown in this paper were realised in the west side of Romania, on the administrative territory of Arad city, Subcetate neighborhood, with the purpose of making a situation plan of the underground infrastructure. More specifically, of the natural gas distribution network. This distribution network incorporates pipes and connections with medium pressure, tuning stations, pipeline stations and connections, valves on pipes and connections. The purpose of this study is the acquistion of the GIS data from this underground network. To create such a plan, we used the Leica Ultra Utility Detection and Trancing System pipe locator to find the network, GNSS Leica Viva GS14 and GS16 to determine the points marked on the route with the locator device, Leica FlexLine TS06 total station to determine the points found on the aerial connections and counters found on fences and constructions. Finally, for proper time management, we used Leica Pegasus: Backpack, which it’s a mobile mapping system. Concerning the detailed topographic surveys, done in a normal way using GNSS equipment and total stations, the use of Mobile Mapping – LiDAR technology offered a real advantage by reducing work time, investigated area and the complexity of the acquired data because the survey was done with the precision of normal equipment. The pros of using geographic information systems and applying them to all sorts of fields have helped spread this concept. The majority of institutions and companies who work with spatial data have initiated a GIS-type project. The complexity of the underground utility network is constantly growing and obtaining precise information regarding the layout of the underground utilities has never been more important. Once all the data is collected on the field, the next part is using this data to create a plan in AutoCad so the database up-to-date with the postal codes, street names, pipe materials, pipe diameters, burial depth, pressure regime, vertical component, length of the main network and that of the embranchment. Some information waa introduced automatically while some needs to be manually put in.
