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 part of a digital compilation of the bedrock geology of Alberta. It is one of the datasets used to produce Alberta Geological Survey (AGS) Map 600. This dataset contains lines representing linear structural elements. In the Rocky Mountains and Foothills these include thrust faults, normal faults and transverse faults as well as the axes of folds (anticlines and synclines). In the Canadian Shield and the Athabasca Basin all faults are given the same symbol (i.e., fault, type unspecified). The data were created in geodatabase format and output for public distribution in shapefile format. AGS Open File Report 2013-02 presents additional information on data sources related to this dataset.

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.

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.
