ABSTRACT

The Commune of Fântânele lies in the Vinga Plain, on the left bank of the Mureş River; it has an area of 4,018 ha. Administratively, it includes the villages of Fântânele, a village 10 km far from the city of Arad and Tisa Nouă. The irrigation system Fântânele – Şagu – Arad is located on the left bank of the Mureş River, which is also its northern limit (from Fântânele to Bodrogul-Nou). The eastern limit is Frumuşeni, and the southern limit is the depression area of the Izvorin Canal from Tisa Nouă to the eastern limit of Mănăştur. The western limit starts from Mănăştur and spreads to the northern limit, Bodrogul-Nou. The irrigation system Fântânele – Şagu – Arad was designed for an area of 9,418 ha (of which 7,154 ha are finished) and it aims at completing the soil moisture deficit during periods with high consumptions of water. The network of pipes was sized for a ponderate mean of the system of 1,200 m3/ha, i.e. three waterings of 400 m3/ha or two waterings of 600 m3/ha. Topographic survey was done with a total station Leica TC805 and Leica 1205+, as well as with GPS equipment from Leica, series 1200. GPS measurements were done with the Romanian System of Position Determining – ROMPOS, a project of the National Agency for Cadastre and Real Estate Publicity that ensures accurate reference positioning and ETRS European coordinates through the National Network of Permanent GNSS Stations. ROMPOS relies on Global Navigation Satellite Systems (GNSS) (future GPS/GLONAS/GALILEO), supplying data for positioning purposes that improve the precision of position determining up to millimetres. In this paper, to make GPS measurements, we used the Real Time Kinematic (RTK) method. Downloading apparatuses was done with the Programme Leica Geo Office Combined. Processing raw data downloaded from GPS was done with the Programme TransDat, with which we transformed the coordinates WGS 1984 into stereographic 1970 coordinates. Raw data from total stations were uploaded in the TopoSys Programme to compensate the station points and radiated points. With the Programme DXF Generate, we processed files with the extension GSI, which we later turned into files with the extension DXF[1]. Compensated points were reported with the Programme TopoLT in AutoCad, with which we made the situation plans. Based on our measurements, we could also make the 3D model of the land and longitudinal and transversal profiles with the Programme ProfLT. Final situation plans for planimetry were made in the stereographic 1970 system and altimetry, with the System Marea Neagră 1975. In this paper, we also made the digital terrain model (DTM), the generic term for digital representations of the land surface. This representation can rely on altitude, which can represent both relief and other topographic details. To achieve the point clouds LIDAR, we used the Programme Global Mapper v.16.1.2, a GIS application that provides access to a variety of sets of space data[2]. For advanced processing, we used the LIDAR module, an optional accessory of the Programme Global Mapper, which provides numerous advanced opportunities for LIDAR processing.
