Purpose:
The DEM raster product has been generated by the contractor from a classified LAS format vector point cloud elevation dataset. The NWOOP 2017 DEM was delivered to MNRF as a derivative product of the NWOOP imagery acquisition project, as it was produced for use in the process of image orthorectification. It is important to note that the DEM does not represent a full ‘bare-earth’ elevation surface. Unassigned classes, where the points not classified as Ground have been removed and interpolation has occurred across the resulting voids. Points classified as Ground have not been assessed for accuracy to determine if they represent true ground features. Some features are still raised above ground surface, such as larger buildings, larger forest stands and other raised features. The product is being distributed in the original state delivered by the imagery contractor without modification.
