Surface materials of the Calgary urban area (GIS data, polygon features)

This is a GIS dataset containing digitized and attributed polygon features from scanned Alberta Geological Survey Maps 201, 202, 203 and 204. The data show the surficial geology of the Calgary urban area (NTS areas 82O/01, 82P/04, 82J/16 and 82I/13) and are attributed with stratigraphic unit, lithology, lithogenesis, morphology, veneer material and the unit labels as shown on the maps. The data from the four maps are presented in a single polygon layer.
