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 ATS v4.1 Polygons - Quarter Section with Road Allowance layer contains polygons that represent the location of Quarter Sections and adjacent 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.

Compiled by Alberta Data Partnerships Ltd. (ADP), on behalf of the Government of Alberta, the ATS v4.1 Polygons - Legal Subdivision (LSD) with Road Allowance layer contains polygons that represent the location of LSD and adjacent 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.

This dataset contain the 1:20,000 scale contour elevation text converted from the Provincial Digital Base Mapping Project. These contours require the use of elevation text to properly interpret the elevation value of a specific contour. There are two major types of contours, index contours and intermediate contours. Index contours are identified every 5th contour line. For Alberta, the index contour intervals occur every 50 metres in relatively flat terrain and every 100 metres in mountainous terrain. Intermediate contours are contour lines that occur between the index contours. For Alberta, the intermediate contour intervals are every 10 metres in relatively flat terrain and every 20 metres in mountainous terrain. Where elevation change is sudden, intermediate contours may be deleted and only index contours are shown. The elevation text is associated with the index contours. Currently, no contour information exists for Banff, Jasper and Wood Buffalo National Parks and also for the extreme north east portion of the province. See the Completeness Report in this metadata record for details regarding coverage.

The Improvement District dataset is comprised of all the polygons that represent large unincorporated rural areas in Alberta. Improvement District is a large unincorporated rural area defined under the authority of the Municipal Government Act and administered under the Improvement District Act. The provincial and federal governments have the primary responsibility in the Improvement District except for school affairs.

This dataset contain the 1:20 000 scale spot height elevation text converted from the Provincial Digital Base Mapping Project. Currently, no spot height information exists for Banff, Jasper and Wood Buffalo National Parks and also for the extreme north east portion of the province. See the Completeness Report in this metadata record for details regarding coverage.

The location of man made areas of importance pertinent to the business activities of the Government of Alberta.

The Hamlet dataset is comprised of all the polygons that represent Hamlets in Alberta. The formation of a Hamlet can occur if there are 5 or more buildings used as dwellings with a majority of which are on parcels of land smaller than 1850 square metres, has a generally accepted boundary and name and contains parcels of land that are used for non-residential purposes. Hamlet is an unincorporated community that can be designated by the council of Municipal District or Specialized Municipality within their boundaries, or by the Minister of Municipal Affairs within the boundaries of an Improvement District.
