The topographic elevation represents a set of field and office works necessary for the realization of a topographic plan. Depending on their content, the topographic elevations can be: planimetric elevations when determining only the position in the plane of the points of the topographic surface, leveling elevations when determining only the vertical position of the points, the combined elevation, when determining both the position in the plane, as well as the vertical position of the points. Topographic survey may be necessary to obtain the building permit, demolition permit, PUG, PUD, PUZ; design of electricity, gas, water and sewerage networks; conclusion of rental, leasing, concession contracts; identifying the real owners of the land on which certain investments are to be executed; obtaining a notice of removal from the agricultural circuit; obtaining the decision to award the postal number. The present work was carried out in Santamaria-Orlea commune, Hunedoara county and aims at the topographic elevation of a sewerage network carried out in the commune as well as in the villages belonging to it. This measurement was made using a Hi Target V30 GPS system, which is the perfect combination of the quality of the materials used in its manufacture and the applied technology. Hi-Target V30 receiver for GNSS RTK measurements is a system that receives signals from multiple satellite constellations, designed to work with the network of ROMPOS reference stations. For the production of the receiver special materials were used, due to the fact that the Hi-Target V30 repeater is extremely resistant to the most difficult weather conditions, it can withstand even under water. The working mode with the V30 receiver can be: rover, base or static. All the working methods as well as the control over the GSM module, the internal radio or the external radio are made from the controller that comes with the Hi-Survey software with which you can modify the working mode. After the completion of the field measurements, the office work was completed, where the machine was unloaded and the measurements were completed to complete the work. In order to carry out the work, I used the AutoCAD (computer aided design) program, which is a CAD program used in the design of two-dimensional (2D), less three-dimensional (3D) construction plans, developed and marketed by the American company Autodesk. The measurements were processed in files specific to the "native" system, which are those of type dwg as well as those of dxf (Drawing eXchange Format), extremely widespread.
