This GIS dataset comprises the geological polygon features of Map 180, Geology of the Precambrian Shield in northeastern Alberta, NTS 74M and NTS 74L, published by the Alberta Geological Survey (polygon features). 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 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.

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 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 .

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 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.

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.

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.

This map displays the risk of soil degradation by wind in the agricultural region of Alberta. Wind erosion is a concern because it reduces soil quality by removing soil nutrients, smaller soil particles and organic matter. Wind erosion can reduce air quality during extreme erosion events and also reduce water quality if eroded particles drift into streams and lakes. The map uses five classes to describe the wind erosion risk on bare, unprotected mineral soil: negligible, low, moderate, high and severe. This resource was created using ArcGIS. It was originally published as a print map in 1989.

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.
