This map displays an assessment of soil erosion risk for the agricultural area of Alberta. Loss of protective residue cover through cultivation will increase the potential risk of soil erosion. The vulnerability of the soil to erosion combined with the intensity of cultivation determines the degree to which the soil may be at risk. The classes shown on the map were ranked from 0 (lowest risk) to 1 (highest risk). This resource was created in 2002 using ArcGIS.

This map illustrates the distribution of soil parent material textures in the agricultural region of Alberta. Soil texture is defined by the relative proportions of the sand, silt and clay particles present. Soil textures are identified by classes using the Soil Texture Triangle illustrated below. The Soil Texture Triangle identifies the textural class of a soil at the intersection of the percent sand (x-axis) and the percent clay (y-axis). The percent silt of the soil is the remainder to add up to 100 percent. This resource was created in 2002 using ArcGIS.

This dataset is a GIS version of the surficial geology line 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 is a GIS version of Alberta Geological Survey (AGS) Map 146, polygon features, as mapped at 1:250,000 scale. 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 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 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 areal features for the Waterways area Alberta (NTS74D), as mapped at 1:250,000 scale by L.A.Bayrock.

This dataset is a GIS version of the linear surficial geology features in Alberta Geological Survey Map 146.

This data set is a GIS version of the surficial geology lithologic contacts 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 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.
