The Provincial Electoral Division - Historical 2003 dataset is comprised of all the polygons that represent the areas in Alberta established as electoral divisions under the Alberta Electoral Divisions Act of May 16, 2003. This dataset is no longer valid and is of historical interest only.

The Provincial Electoral Division - Historical 2010 dataset is comprised of all the polygons that represent the areas in Alberta established as electoral divisions under the Alberta Electoral Divisions Act of December 2, 2010. This dataset reflects the legally valid boundaries for provincial general elections and for provincial by-elections, and supersedes all previously published electoral division datasets.

The Alberta Provincial Boundary dataset is a polygon that represents the bounding limits of the Province of Alberta as of February 2007. This version of the boundary has been superseded by the ATS v4.1 Alberta Provincial Boundary, published April 2010.

The Phase 1 (Broad Scale) Forest Inventory was initiated in 1949 and completed by 1956. The Phase 1 (Broad Scale) Forest Inventory included all publicly owned forested lands in the province except Indian lands, national parks, and an area known as the Rocky Mountains Forest Reserve. The Phase 1 (Broad Scale) Forest Inventory was used to define lands suitable for agriculture, to determine timber harvest levels and plan forest protection and timber and industrial development. Through aerial photo interpretation, land was classified as productive, potentially productive, or non-productive. On productive forest land, homogeneous groups of trees were classified by 'cover types'. Cover types included crown density, height and tree species. Burned, harvested or cultivated land was identified as potentially productive. Non-productive lands included areas with organic soils, barren rock and lakes. No ages or site classes are associated with the polygons. The minimum polygon size was 65 ha. These maps are not available as geo-referenced rectified images or GIS-ready data.

This data collection contains various historical features within Alberta related to the Dominion Forestry Branch (DFB), and the early days of the Alberta Forest Service (AFS). The data collection consists of the following: Historical Forest Reserve Boundaries (1900 to 1930). Timber Berth boundaries (1910 to 1923). Early Ground and Aerial Fire Patrol Routes. Air Stations (1920s). Locations of DFB Forest Surveys (1910 to 1915). AFS Forest and District Boundaries (circa 1938). These datasets provide approximate locations of the features they represent and are intended for use in medium to small-scale mapping. No spatial accuracy tests were conducted on any of the data. Features derived from land locations tied in the Alberta Township System (ATS) are likely to be accurate providing there were no errors in transcribing the locations. However features digitized from old maps will have poor spatial accuracy ranging from several kilometres to a few hundred metres, depending on the map scale, map projection, and the accuracy of the features on the source map.
