This paper aims at calculating volumes at landfills and designing the volume of waste on a topographic site, with a view to the greening of the respective deposits. The work was carried out at the landfills in Bocşa and Herculane localities from Caraş Severin County, Alba Iulia from Alba County and Viseu de Jos from Maramureş County. The measurements were made using a Trimble 4800 GPS, using the Rompos permanent stations. Rompos is based on global navigation systems via GNSS satellites (GPS / Glonas / Galileo), providing data for positioning purposes. At present, the positioning system provides coverage of the entire Earth’s surface, being in the same time a unitary reference system, so called global positioning system (GPS) with satellites. Global Navigation Satellite System (GNSS) uses the positioning technique of objects in moving and / or static at any hour from day and night, 24 hours a day, anywhere on Earth, with real-time information delivery The reason for using multiple reference stations in a GPS correction network is to model and correct the errors dependent of distance, that reduce the precision of the RTK position in proportion to the distance between the Rover and the nearest reference station. Monitoring and control of the permanent GPS station is made through a simple internet connection of the computer serving this station. The Trimble 4800 GPS software allows this connection through the functions it holds. Static and cinematic measurements (RTK) were made within the frame of this paper, static measurements were made for determination of the building site markers and the kinematic ones for the calculation of the waste volumes being in the respective locations. The volumetric calculation was processed by using a SurvCe software, version 2.3 and by using of AUTOCAD MAPS 2012, TOPOLT 11.2 program.
