Bedrock Topography and Sediment Thickness Mapping in the Edmonton-Calgary Corridor, Central Alberta: An Overview of Protocols and Methodologies

Alberta Geological Survey developed a series of protocols to generate regional bedrock topography and overburden-thickness maps as part of a broader groundwater-mapping project for the Edmonton-Calgary corridor (ECC).

These methods let us generate bedrock topography and sediment thickness maps for the ECC. The pseudo-automated methods let us quickly integrate and analyze large geo-datasets compiled from various sources. In addition, these methods provide future investigators with a user-friendly means of map upkeep through the integration of newly acquired data.

These methods allow one to delineate bedrock topography, in particular the spatial distribution of potential groundwater exploration targets, at a regional scale. The report�s maps can form the basis for future regional-scale groundwater studies, aggregate resource assessments, geotechnical work and other land-use applications.
