This map displays the risk of soil degradation by water in the agricultural region of Alberta. Water erosion is a concern because it reduces soil quality by removing soil particles and nutrients, and reduces water quality if these particles are carried into nearby water bodies. The map uses five classes to describe the water erosion risk on bare, unprotected mineral soil: negligible, low, moderate, high and severe.This resource was created using ArcGIS, originally published as a print map in 1993 .

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 31 of the Atlas, Petroleum Generation and Migration in the Western Canada Sedimentary Basin, Figure 3, Ordovician Petroleum System. 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 14 of the Atlas, Carboniferous Strata of the Western Canada Sedimentary Basin, Figure 32, Carboniferous 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 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 6, Lithotectonic Basement 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.

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 data set is a GIS version of the surficial geology areal features for the Bitumount area Alberta (NTS74E), as mapped at 1:250,000 scale by L.A.Bayrock.
-
This data set is a GIS version of the surficial geology linear features for the Bitumount area Alberta (NTS74E), as mapped at 1:250,000 scale by L.A.Bayrock.
-
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 dataset is a GIS version of the surficial geology point 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).

The data represents the occurrence of saline soils in the agricultural area of Alberta. A Saline Soils is a non-alkali (pH less than 8.5 and exchangeable-sodium less than 15%) soil containing soluble salts in great enough quantities that they interfere with the growth of most crop plants. This resource was created in 2002 using ArcGIS.
