    This GIS dataset comprises the bedrock contacts (polygon outline features) of Map 180, Geology of the Precambrian Shield in northeastern Alberta, NTS 74M and NTS 74L, published by the Alberta Geological Survey. The data are created in ArcInfo and output for public distribution in shapefile format.

    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 Alberta Ground Cover Classification Mosaic is a land cover dataset for the province of Alberta. It is a composite of the Alberta Ground Cover Classification (AGCC) created by Alberta Environment and Sustainable Resource Development for the green areas of the province and the Land Cover for Agricultural Regions of Canada, circa 2000 created by Agriculture and Agri-Food Canada for the white areas of the province.

    This map displays the distribution of Solonetzic soils in the agricultural region of Alberta. Solonetzic soils have developed on saline parent material that is high in sodium and have a characteristic hardpan layer that has formed in the subsoil. This hardpan is very hard when dry and has low permeability when wet. This results in restricted root and water penetration that may limit the productivity of these soils. Solonetzic soils occur in association with Chernozemic soils and, to a lesser extent, with Luvisolic soils.The Agricultural Region of Alberta Soil Inventory Database (AGRASID) soil landscape polygons that contained soils belonging to the Solonetzic Order were identified, and the areal extent of these soils was represented as a percentage of the total area using the following classes: greater than 30, 10 to 30 and less than 10. This resource was created in 2002 using ArcGIS.

    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 18 of the Atlas, Jurassic and Lowermost Cretaceous Strata of the Western Canada Sedimentary Basin, Figure 17, Jurassic Structure. 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 dataset is a GIS version of the surficial geology areal features for the Fort Chipewyan area, Alberta (NTS 74L) , as mapped at 1:250,000 scale by L.A. Bayrock (Alberta Geological Survey Map 141).

    This dataset was digitized from an unedited version of surficial geology map of the Wapiti area, NTS 83L, compiled by Laurence Andriashek in 1983 (Alberta Geological Survey Open File Report 1983-23). Mapping scale is 1:250,000.

    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 data set is a GIS version of the surficial geology areal features' outlines, i.e., map unit contacts, for the Waterways area Alberta (NTS74D), as mapped at 1:250,000 scale by L.A.Bayrock.

    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 14 of the Atlas, Carboniferous Strata of the Western Canada Sedimentary Basin, Figure 35, Stoddart/Mattson/Kibbey 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 map displays the percentage of organic matter in the surface layer of cultivated soils in the agricultural region of Alberta. Soil organic matter (SOM) is derived primarily from the decomposition of plant biomass. SOM improves both the physical and chemical properties of soil and has beneficial effects on agricultural soil quality. SOM is reported on the map as a percentage using the following classes: less than 2 (very low), 2 to 4 (low), 4 to 6 (medium), 6 to 8 (high) and greater than 8 (very high).This resource was created in 2002 using ArcGIS.
