AEROTERRA, is working with utility companies (telephone, electricity, gas, waters and others) and offers to each one of them, the solutions for many of their problems.

Depending on the precision and scale of the project, we produce:

Regional Databases including:

Thematic Mapping of infrastructure, hydrology and land use obtained from the analysis of Landsat 7, RADARSAT, ERS and SPOT data. Topographical data obtained through interferometry and/or stereo-pairs of radar images and digitizing of topo maps.

Urban Databases including:

Photogrammetric flights (color and B&W) 2D and 3D Compilation (constructions, parcels, etc.) Image Analysis (SPOT and IKONOS) Digital Elevation Models Thematic Mapping Collection of ground truth Ground surveys GIS modelling and analysis

• Orthoimages and aerial orthos.

• Planimetric and topographical mapping at different scales.

• Satellite Thematic Mapping at different scales.

• Planimetric and topographic compilation.

• Digital Elevation models of different resolutions.

• Simulation of emission patterns.

• Terrain Modelling.
