20K DEM
Fort McMurray
A Digital Elevation Model (DEM) is a digital representation of ground surface topology or relief. The 20K DEM contains three dimensional spatial ground elevation masspoints, which are spot elevation points, hard breaklines, which include cliffs, ridges, peaks, and bodies of standing water, and soft breaklines that include all other hydrographic features.
These coordinate files were compiled in 1980 - 1995 with 1:60 000 scale air photography and can be imported into external software for the generation of 3D renderings and 3D surface analysis.
