These three datasets were processed separately and tiled seamlessly along their borders. The Digital Elevation Model Alberta 1980 1995 60K was compiled from 1:60 000 scale aerial photography using analytical stereoplotters with vegetation and structures excluded. The Digital Elevation Model Northeastern Alberta 1955 1986 50K dataset was created primarily…
