Elevation data was derived for aerial photographs by Alberta Environmental Protection and distributed in Digital Map Data Format (DMDF). The DMDF was developed to permit transmission of digital map data in a format which is hardware independent and contains the minimum amount of information required to convert the data to graphic files. The format segregates map features into four basic points; points, curves, line strings or annotation.

- Process Description:
-
The DMDF files were converted into a readable format for ARCINFO in building tins. The tins were built and converted into a raster data model and the resulting ARC/INFO lattices were processed into DEM's.
