Elevation Data

GeoQode has the necessary tools and expertise to create DSM/DEM products from a sequence of overlapping aerial photos and/or LIDAR data. GeoQode creates high quality Digital Elevation Models (DEMs) to support specialized applications such as 3D modeling, volumetric calculations, powerline as-built surveys, contour generation, orthophoto rectification, and flood plain mapping.

Common uses of DEMs include:

 

  • Extracting terrain parameters for geomorphology

  • Modeling water flow for hydrology or mass movement (for example avalanches and landslides)

  • Creation of relief maps

  • . Rendering 3D visualizations

  • Creation of physical models (including raised relief maps)

  • Orthorectification of aerial photography or satellite imagery

  • Creation of True Orthophotos

  • Reduction (terrain correction) of gravity measurements (gravimetry, physical geodesy)

  • Terrain analysis in geomorphology and physical geography

  • Geographic Information Systems (GIS)

  • Engineering and infrastructure design

  • Base mapping

  • Flight simulation

  • Precision farming and forestry

  • Surface analysis

  • Intelligent transportation systems

  • Auto safety / Advanced Driver Assistance Systems (ADAS)
