Surface materials of the Calgary urban area - veneer material (GIS data, polygon overlay 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 supplemental surficial geology of the Calgary urban area (NTS areas 82O/01, 82P/04, 82J/16 and 82I/13). Polygons, representing a discontinuous layer, are attributed as sand and silt veneer or buried sand, as shown on the maps. The data from the four maps are presented in a single polygon layer.
