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.
