This department develops the establishment of electronic traverses, topographic surveys, leveling networks, layout and layout of works, etc.
It also establishes geodetic control networks based on precision satellite positioning and polygonal support linked to the UTM coordinate system with WGS84 and/or PSAD56 datum. It provides coordinate transformation services, ground control for aerial photogrammetry, georeferencing of satellite images, rural and urban cadastre, execution of topographic surveys through the use of real-time positioning (GPS RTK).
It also directly develops bathymetry in the sea, lakes, rivers and reservoirs, using its own equipment such as the multi-frequency electronic echo sounder and GPS RTK.
It makes full use of Geographic Information Systems (GIS), including global position determination technologies, remote sensing, digital mapping, photogrammetry, high resolution satellite images; integrating them in the GIS for the adequate analysis applicable to the company's projects.
