Terrain Terrain

Terrain Overview

The Alberta Digital Elevation (DEM) data contains three dimensional spatial ground elevation values representing grid points, break lines, and spot heights. LiDAR15 DEM has been collected by LiDAR technology and processed into 15 meter post spacing, XYZ ASCII coordinates.

LiDAR data (Light Detection and Ranging' or 'Laser Imaging Detection and Ranging') provides extremely accurate and detailed 3D measurements of the ground, vegetation, and buildings.

AltaLIS terrain products are used for rendering 3D visualization applications, landscape modeling, terrain analysis, raised relief maps, and more.
