DEM Digital Elevation Model

DEM digital elevation model is a 3D representation of the terrain elevations
found on surface of the earth. DEMs are generated from variably-spaced Lidar
ground points, or they can be created using a raster grid.
Feiyan Technology focus on creation of high quality DEM Digital Elevation
Model to support specialized applications such as 3D modeling, volumetric
calculations, and powerline as-built surveys.
