DIGITAL TERRAIN MODELS
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.
SATELLITE IMAGERY
We produce color or panchromatic orthophotos/orthophoto mosaics by photogrammetry and Structure-from-Motion processing techniques in various spatial resolutions, combining the geometrical accuracy of a topographical map with the qualitative information we can derive from a high resolution satellite image.
As on demand services, we deliver digitized topographical maps, change detection analysis and land-cover mapping in multispectral images.
