Abstract: 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.

Using geostatistical techniques, we excluded outlier bedrock top elevation points from the modelling process. Result: unknown Report: Conceptual consistency: Measure description: This surface defines the top of the bedrock in the Edmonton-Calgary Corridor. It is in ArcGIS ASCII grid format. Grid cells with no data are assigned the value -9999. Result: unknown Lineage: Lineage: Statement: We manually assessed duplicate location data and culled them if the bedrock top elevations contradicted each other. Using geostatistical techniques, we excluded outlier bedrock top elevation points from the modelling process. Process step: Process step: Description: We modelled the bedrock top elevations from the Edmonton-Calgary Corridor geological mapping database and bedrock outcrop locations in ArcMap. Based on geostatistical analysis, the bedrock topography in the Edmonton-Calgary Corridor shows a clear trend, increasing to the southwest toward the Rocky Mountains. A global first-order polynomial accounted for this trend. We evaluated higher order polynomials, but these provided no further improvement to the model and added unnecessary complexity. The residual values (measurements minus the trend) were modelled using ordinary kriging, which accounted for local variations in the trend value. The final model was produced by adding the global trend to the estimated residuals. Determining bedrock topography involves a three-step process: kriging, assessing the quality and fit of the modelled surface to the data (QA-QC) and re-kriging if necessary. This process is described in Alberta Geological Survey Open File Report 2010-12. Date and time: 2009-01-01T00:00:00
