We recreate Digital Terrain Models (DTMs) from Aerial Photos or Satellite Stereo Imagery by photogrammetry and
Structure-from-Motion processing techniques for a wide range of topographical and geotechnical applications, with demands in 3D Spatial Basemaps
in fine resolutions and accuracies. Digital Terrain Models serve as 3D basemaps in GIS mapping and analysis, infrastructure design projects,
conceptual designs, construction projects and sites development. Ask as to deliver spatial analysis sub-products such as slope and aspect analysis maps,
hillshading models, watershed analysis rasters and vectors, elevations contours, etc.
Monitor elevation changes and perform precise volume calculations in different time periods for the same area of interest.
