Compiled by Alberta Data Partnerships Ltd. (ADP), on behalf of the Government of Alberta, the ATS v4.1 Polygons - Quarter Section with Road Allowance layer contains polygons that represent the location of Quarter Sections and adjacent dissolved Road Allowance Segment polygons, derived from the Master Alberta Township System points file published as ATS Version 4.1, dated March 31, 2005, and clipped to an updated Alberta Data Partnerships Ltd. (ADP) created version of the Alberta provincial boundary.

This is a dataset of forest harvest areas for the Upper North Saskatchewan and Upper Red Deer River Basins of Alberta. This dataset was created to support spatial analyses of forest harvest areas in the Upper North Saskatchewan and Upper Red Deer River Basins for the Alberta Environment and Parks report entitled “Ecological response to land use and human activities in the eastern slopes of Alberta's Rocky Mountains: A scientific assessment”. This is a polygon dataset covering the Upper North Saskatchewan and upper Red Deer River Basins of Alberta, Canada for the period 1961-2016. This dataset of forest harvest areas was created using three data sources obtained from Alberta Agriculture and Forestry: The AVI (Alberta Agriculture and Forestry, 2017a), the Post Inventory Final Cutblocks layer (Alberta Agriculture and Forestry, 2017b), and Regional Forestry Cultblock data (obtained directly from Alberta Agriculture and Forestry, March 2018). For further details, see report entitled “Land use, climate change and ecological responses in the Upper North Saskatchewan and Upper Red Deer River Basins: A scientific assessment”, available at: https://open.alberta.ca/publications/9781460140697. Please note: this legacy dataset will not be updated. For questions regarding the data, please contact AEP.Data@gov.ab.ca.

Compiled by Alberta Data Partnerships Ltd. (ADP), on behalf of the Government of Alberta, the ATS v4.1 Polygons - Township Index polygon layer contains polygons that represent the location of Township polygons, derived from the Master Alberta Township System points file published as ATS Version 4.1, dated March 31, 2005, and clipped to an updated Alberta Data Partnerships Ltd. (ADP) created version of the Alberta provincial boundary. No road allowance segments are included in this layer.

Compiled by Alberta Data Partnerships Ltd. (ADP), on behalf of the Government of Alberta, the Alberta Provincial Boundary ATS v4.1 polygon layer contains the polygon that represents the location of the boundaries of the Province of Alberta. This version of the Province of Alberta boundaries should be considered definitive for Government of Alberta use, and supersedes all previous versions.

The Alberta Transportation Region dataset is comprised of all the polygons that represent Alberta Transportation Regions in Alberta. The Transportation Region is the first level of administrative zones established by Alberta Transportation to manage roads (primary and secondary highways) under their jurisdiction. Alberta Transportation Region is sub-divided into Alberta Transportation District.

The Alberta Transportation District dataset is comprised of all the polygons that represent Alberta Transportation Districts in Alberta. The Transportation District is the second level of administrative zones established by Alberta Transportation to manage roads (primary and secondary highways) under their jurisdiction. Alberta Transportation District indicates the subunits of Alberta Transportation Region.

The Alberta Provincial Terrain is a component of the Alberta Provincial Digital Elevation Model. The Alberta Provincial Digital Elevation Model has five components: the Alberta Provincial Terrain, the Alberta Provincial 25 Metre Raster, the Alberta Provincial 100 Metre Raster, the Alberta Provincial 25 Metre Hillshade and the Alberta Provincial 100 Metre Hillshade. The source data is contained within the feature dataset that houses the Alberta Provincial Terrain. The source data consists of feature classes generated from the mass points, soft breaklines and hard breaklines that were stored as ASCII generate files in 1:20 000 scale National Topographic System (NTS) blocks. The source data has three origins: Digital Elevation Model: Alberta 1980 1995 60K, Southwestern Alberta 1979 1996 50K and Northeastern Alberta 1955 1986 50K. These three datasets were processed separately and tiled seamlessly along their borders. The Digital Elevation Model Alberta 1980 1995 60K was compiled from 1:60 000 scale aerial photography using analytical stereoplotters with vegetation and structures excluded. The Digital Elevation Model Northeastern Alberta 1955 1986 50K dataset was created primarily from 1:50 000 scale contour and hydrography data acquired from Natural Resources Canada (NRCAN) with supplementary aerial triangulation points derived from 1:60 000 scale black and white aerial photography dating between 1980 and 1995. The Digital Elevation Model Southwestern Alberta 1979 1996 50K dataset was created primarily from 1:50 000 scale contour and hydrography data from Natural Resources Canada, using Geographic Information System (GIS) processes that recognise the relationship between surface contours and hydrography. The Alberta Provincial Terrain is an ArcGIS terrain dataset that is built from feature classes. Terrains are TIN (Triangulated Irregular Network) -based representations of a surface and must reside inside of a geodatabase. The surface is displayed as triangles with an elevation point at the apex of each triangle. Pyramids are built into the terrain structure to generalize the display of the triangulated surface at different scales. Some analysis can be conducted using terrains but gridded data, such as a raster or a lattice, is often more useful. The Alberta Provincial Terrain is used as a base to generate the Alberta Provincial 25 and 100 Metre Rasters.

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).
