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.

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.

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 (linear landforms) of the Calgary urban area (NTS areas 82O/01, 82P/04, 82J/16 and 82I/13). Features shown on the maps include fresh and buried scarps, minor traverse ridges, streamlined glacial landforms and buried valleys . The data from the four maps are presented in a single line layer.

This GIS dataset is a compilation of existing surficial map information for the Calgary-Lethbridge Corridor area tiled into one layer. It is suitable for presentation and use at 1:250 000 scale. The dataset was prepared by appending existing GIS datasets into one layer with a standard attribute table. These datasets were then compared against surficial maps for which GIS data were unavailable. Lastly, polygon boundaries were modified to agree with the surface topography as represented by a digital elevation model (DEM) with a grid cell size of 25 metres. Data sources included published Alberta Geological Survey and Geological Survey of Canada maps and the Agricultural Regions of Alberta Soil Inventory Database Version 4.0. Legend information for each polygon was translated by the author into the standard schema. This dataset contains the polygon features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in shapefile format for public distribution.

This GIS dataset portrays the distribution of glacial landforms within the Calgary-Lethbridge Corridor area, based on the compilation of existing government survey mapping and research literature, supplemented by new analysis of remote sensing data. The original line features have been modified where necessary for map production at 1:250 000 scale. This dataset contains the line features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in a shapefile format for public distribution.

This GIS dataset depicts the structural bedrock top surface in the Edmonton-Calgary Corridor based on water-well litholog data, including bedrock outcrop locations. We sourced the well data from an internal Edmonton-Calgary Corridor geological mapping database. This surface provides a geological model for the region. These data comprise the raster surface of Alberta Geological Survey Map 549, Bedrock Topography of the Edmonton-Calgary Corridor, Alberta.

This GIS dataset is a GIS version of AGS Map 150, Sheets 1 - 6, as mapped at 1:250,000-scale by Bayrock and Reimchen. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to AGS by PFRA in individual map sheets, in Arc/Info coverage format. Data were subsequently checked and edge-matched to create a single polygon coverage. Some rubber-sheeting and other edits were done during the checking and correction process.

This dataset is a GIS version of Alberta Geological Survey (AGS) Map 146, polygon features, as mapped at 1:250,000 scale. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to AGS by PFRA in Arc/Info coverage format (map polygon features only). Data were subsequently checked and edited by AGS.

This GIS dataset is part of a GIS version of AGS Map 150, Sheets 1 - 6, as mapped at 1:250,000-scale by Bayrock and Reimchen. The data represent the glacial features component of the maps.

This GIS dataset depicts the surficial geology of the NTS map area 84N northwest (polygon features). The data are created in geodatabase format and output for public distribution in shapefile format.
