Surface materials of the Calgary urban area - geological contacts (GIS data, line features)

This is a GIS dataset containing digitized and attributed line 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 geological contact boundaries defined and inferred as shown on the maps. The data from the four maps are presented in a single line layer.
