The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 27 of the Atlas, Geological History of the Williston Basin and Sweetgrass Arch, Figure 5, Sweetgrass Arch and Williston Basin Tectonic Elements. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 17 of the Atlas, Paleographic Evolution of the Western Canada Foreland Basin, Figure 9, Bow Island/Viking/Paddy/Newcastle Paleogeography. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

This cartographic quality series of 1:2 000 000 scale colour maps cover the provincial extent of Alberta. The primary provincial base map displays the Alberta Township System (ATS), major hydrographic features, municipalities, major roads, railways and select geoadministrative features (parks, reserves, etc.). In addition to the primary provincial base map, this series includes various themes that overlay the primary base map. The update of this map series is based on the provincial Base Features Access Update Program that has an approximate 5 year update cycle. Each individual map sheet is provided in Adobe .pdf format.

All available bathymetry and related information for Manatokan Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 19 of the Atlas, Cretaceous Mannville Group of the Western Canada Sedimentary Basin, Figure 4, Mannville Isopach. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

A digital grid of the subcrop edge of the Grand Rapids Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present (denoted by the number '100'), or where it is absent (denoted by the null value '-9999'). The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.

This cartographic quality series of 1:1 000 000 scale colour maps cover the provincial extent of Alberta. The primary provincial base map displays the Alberta Township System (ATS), major hydrographic features, municipalities, major roads, railways and select geoadministrative features (parks, reserves, etc.). In addition to the primary provincial base map, this series includes various themes that overlay the primary base map. The update of this map series is based on the provincial Base Features Access Update Program that has an approximate 5 year update cycle. Each individual map sheet is provided in Adobe .pdf format.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 16 of the Atlas, Triassic Strata of the Western Canada Sedimentary Basin, Figure 2, Triassic Isopach. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The data represents the relative expense of farm chemicals (herbicides, insecticides and fungicides) in the agricultural area of Alberta. It is an estimate of the degree to which crop production agriculture may contribute to surface or groundwater contamination.Agriculture production that makes greater use of herbicides, insecticides and pesticides in generally considered more intensive. Presenting the relative farm chemical expenses by SLC polygons reveals where the most intensive agricultural production in the province occurs. Chemical use is part of an equation to determine a measure of surface water quality risk. If an area is known to have certain risk factors that …

This digital data release includes helium pycnometry results of selected samples for analyses of shale- and siltstone-hosted hydrocarbons. The strata evaluated include the: - basal Banff Formation, - Colorado Group, - Duvernay Formation, - Exshaw Formation, - Montney Formation, - Muskwa Formation, - Wilrich Formation, - Nordegg Member, and - Rierdon Formation.
