Structure Top of the Paskapoo Formation, Alberta (Gridded data, ASCII format)
This dataset represents the topography of the top of the Paskapoo Formation, which is also the bedrock topography in the western part of Alberta. We clipped the surface from Alberta Geological Survey's Bedrock Topography of Alberta grid using the areal extent of the Paskapoo Formation shown on Alberta Geological Survey Map 236, Geological Map of Alberta. The dataset is in ESRI ASCII grid format
Reconnaissance Karst Potential Mapping
An interpretation of bedrock geology, topography and other sources of information that shows the potential for karst formations. This is a reconnaissance level map for all of British Columbia
Pick Elevations for the Bedrock Topography of the Alberta Plains (tabular data, tab delimited format)
The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This dataset consists of previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data for which the quality has been assessed in order to apply a quality-weighting approach prior to modelling the bedrock topography surface. It is the data used to produce AGS Map 602, Bedrock Topography of Alberta. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of physiographic terrain elements of the bedrock surface across Alberta, and the sources and quality of the data that were used to interpolate this surface.
Bedrock geology index map
The Bedrock Index provides a spatial record of the location of all Bedrock maps published by the Geological Survey of Canada and hosted on Geoscan. The index has three "series" of maps; CGM, A series, and preliminary maps. In cases where there have been multiple editions of a map, the most recent record is reported in the Bedrock Index attribute table. Maps published in Open File documents are not recorded in the bedrock index. The "A" series maps were produced from 1909 to 2010 and have been replaced by the CGM (Canadian Geoscience Maps) series. CGM maps began production in 2010 and are still being published. Preliminary maps were published from 1941 to 2021.
Bedrock Geology
British Columbia Digital Geology is the data source used for the seamless province-wide, up-to-date, and detailed bedrock geology. The bedrock geology is standardized with consistent stratigraphic code and geometries, and integrates all details of compilations from 1:50,000 to 1:250,000. The latest release (Open File 2017-8) is maintained by a geospatial frame data model, which consists of attributed geological contacts and faults as linework, and outcrops or centroids as points attributed with bedrock information. Techniques are used to simplify the integration process and shorten the timeframe from field mapping, compilation, integration, to data delivery. The release also contains: tables for geological units and colours; ESRI layer files containing bedrock colour symbols; and a map of British Columbia illustrating the suggested colour theme for the bedrock polygons. Related data sets are Geology Faults and Quaternary Alluvium and Cover. Bedrock Geology is interactive with other geoscience data on MapPlace and MapPlace 2 and is available for download in shapefile format.
Bedrock Topography of Alberta (gridded data, ASCII format)
The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This grid is a computer-generated geostatistical model of the bedrock topography of Alberta using previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data. The quality of this data has been assessed and then a quality-weighting approach was applied to the dataset prior to interpolation. The surface was modelled using a 500m x 500m grid cell spacing, and as such should not be used for local scale studies. This grid represents the surface portrayed in AGS Map 602, Bedrock Topography of Alberta, and this grid will continue to be updated as part of the Alberta Geological Framework project. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of physiographic terrain elements of the bedrock surface across Alberta, and the data sources and geostatistical methods used to interpolate this surface.
Bedrock Topography of Bistcho Lake Area, Alberta (NTS 84M) (GIS data, line features)
This GIS dataset depicts the bedrock topography of NTS map area 84M (line features). The data are created in ArcGIS and output for public distribution in shapefile formats.
Geology Faults
Geology faults are part of the British Columbia Digital Geology, which is the data source used for the seamless province-wide, up-to-date, and detailed bedrock geology. The bedrock geology integrates all details of compilations from 1:50,000 to 1:250,000. The data is maintained by a geospatial frame data model with techniques used to simplify the integration process and shorten the time frame from field mapping, compilation, integration, to data delivery. Geology faults with the related data sets, Bedrock Geology and Quaternary Alluvium and Cover, are displayed on MapPlace and MapPlace 2 and is available for download in shapefile and GeoPackage formats.
Bedrock Topography of Alberta, Canada (Gridded data, ASCII format)
This GIS dataset depicts the result of a geostatistical model of the bedrock topography in Alberta. This model is based on water-well litholog data, stratigraphic picks made on oil and gas petrophysical logs, data derived from digitized contour interpretations on bedrock topography maps, including bedrock outcrop locations and the 60 m grid-spaced Shuttle Rader Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 550, Bedrock Topography of Alberta, Canada.
Bedrock Topography of the Edmonton-Calgary Corridor, Alberta (GIS data, ASCII grid format)
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.
