With the newest technology, at Geo Digital we collect and process terrain and surface information to generate contour lines,

3D models, slope analysis, pluvial flood risk analysis, volumetry, structural analysis, and more.

Aero LiDAR: Ultra-high resolution and precision

DTM, DSM, and topographic contours.

With LiDAR scanners mounted on a drone, fixed-wing aircraft, or helicopter. For small, medium, or extensive coverage projects that require greater precision and resolution (contour lines from 10 cm equidistance), with precisions from 3 cm in elevation and from 4 cm horizontally.    Furthermore, with this technology it is possible to obtain the first surface that allows studies of biomass, high voltage lines, constructions and more.

Raster or Vectorial Digital Elevation Models

With state-of-the-art technology, Geo Digital Imaging process 3D data to offer you precise models for your projects. Derived Elevation Models are compatible with your software and are delivered in any required Spatial Reference System.

 
Among the Digital Elevation Models (surface and terrain), Geo Digital Imaging process any other products required by your Organization:

​​

• ​Volumetric estimation (pits, platforms, fills, dumps)

• Relief Models procesed to enhance structural characteristics in the surface.

• Orthofoto in high-resolution, natural color.​

• Slope calculation for terrain stability analysis associated with lithological units.

• Flow direction determination

• Map fusion and imagery to produce surface maps in 3D.

 
 

 

​

DTM, DSM, and contours from satellital stereo-pairs

For projects of very wide coverage which requires high precision and resolution (contours up to 50-centimeter in equidistance).  The precisions of this models can be enhanced with ground control points.

​

High-resolution photogrammetric flights

Conventional photogrammetric flights using industrial-grade UAV's, fix-wing airplanes, or helicopters to produce digital terrain models, digital surface models, contour levels, and ultra-high-resolution and precision orthophotos.

​

​

Elevation contours from public models

Reprocessed and resampled by us from sources like SRTM2 (world wide), ASTER GDEM (world wide), USGS (US) or INEGI (Mexico), for projects of wide coverage and medium precision (contour levels up to 10-meter in equidistance).

Elevation contours with high-precision GPS, with mobile double frequency equipment, for small coverage and medium resolution.

 

Terrain characteristics for different applications, from urbanism to archaeological works. Geo Digital Imaging have the right solution for all of your needs.
