Lineage
- Description
- The DEM has been generated from the unthinned LiDAR returns classified as ground. Triangles are drawn between the three nearest ground points and the area weighted average of the surrounding triangles is used to determine the elevation of grid cell centroids. The DEM has been interpolated across voids caused by diminished returns due to water-bodies and the removal of vegetation and buildings.
