Ecological Land Classification (ELC) is an approach which endeavours to subdivide the landscape into significant ecological units and to organize complex interrelationships into identified geographical areas with similar properties. It is a hierarchical system that captures information at the following scales as per the Ecological Land Classification and Evaluation Reference Manual (1980): Ecoprovince - >1:3 000 000 Ecoregion - 1:1 000 000 - 1:3 000 000 Ecodistrict - 1:250 000 - 1:1 000 000 Ecosection - 1:100 000 - 1:250 000 Ecosite - 1:10 000 - 1:20 000 Ecoelement - 1:1 000 - 1:5 000. Note that the upper two levels are referred to as Natural Region and Natural Subregion in the more recent Ecological Land Classification reports. There are also some variations in this hierarchy for individual study areas. The data is available as TIFF image files packaged together with the reports and other supporting documents divided alphabetically.

This data set is a GIS version of the surficial geology lacustrine deposit features for the Waterways area Alberta (NTS74D), as mapped at 1:250,000 scale by L.A.Bayrock. It serves as an overlay on the polygon features that depict the map units.

This GIS dataset is a GIS version of Alberta Geological Survey Map 139, polygon features, as mapped at 1:250,000 scale. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to Alberta Geological Survey (AGS) by PFRA in Arc/Info coverage format (map polygon features only). Data were subsequently checked and edited by AGS.

This data set is a GIS version of the surficial geology linear features for the Waterways area Alberta (NTS74D), as mapped at 1:250,000 scale by L.A.Bayrock.

This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The Ecological Land Classification (ELC) Status is a supporting dataset to the Ecological Land Classification dataset. The ELC Status represents a geodatabase feature class of the ELC study areas. There is attribution to describe the scale of the study, whether there is a scanned report (.pdf), scanned map (.tif) or GIS-ready feature class available.

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 9 of the Atlas, Middle Ordovician to Lower Devonian Strata of the Western Canada Sedimentary Basin, Figure 22, Ordovician-Silurian Subcrop/Outcrop Williston Basin. 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 GIS dataset is a GIS version of AGS Map 178, polygon features, as mapped at 1:250,000-scale by Fenton and Andriashek. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to AGS by PFRA in Arc/Info coverage format (map polygon features only). Data were subsequently checked and edited by AGS.

This GIS dataset is one of a collection of shapefiles representing part of Chapter 9 of the Atlas, Middle Ordovician to Lower Devonian Strata of the Western Canada Sedimentary Basin, Figure 23, Winnipeg Isopach and Lithofacies. 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 data set is a GIS version of the surficial geology drumlin features for the Bitumount area Alberta (NTS74E), as mapped at 1:250,000 scale by L.A.Bayrock. Polygons represent the areal coverage of the drumlins, and no attributes are available.

This data set is a GIS version of the surficial geology point features for the Waterways area Alberta (NTS74D), as mapped at 1:250,000 scale by L.A.Bayrock.
