The 2011 Census Agricultural Regions Boundary Files are available for download from the Statistics Canada website in the following formats:
- ArcGIS® shapefile format version 9.3.1. File extension: .shp
- MapInfo® format version 11.0.1. File extension: .tab
- Geography Markup Language (GML) version 3.1.1. File extension: .gml
The ArcGIS®, MapInfo® and GML files are compressed into WinZip® files (file extension .zip).
An XML schema file (.xsd) is included to describe and validate the structure and content of the .gml files.
The geographic area names in the CAR boundary files contain accented characters. These characters can be seen in UNIX and Windows® versions of ArcGIS® and MapInfo®. They were tested on desktop versions of ArcGIS® 9.3.1 and MapInfo® 11.01.1.
The 2011 Census Agricultural Regions Boundary Files are available for free on the Statistics Canada website in the following geographic representation:
- Datum: NAD83
- Coordinates: Latitude / Longitude
To ensure calculations are relevant (e.g., to calculate land area), it is recommended that the latitude/longitude coordinates be transformed to an appropriate map projection.
The conventions used are:
- ArcInfo® shape file gcar000a11a_e.shp, gcar000b11a_e.shp
- MapInfo® TAB file gcar000a11m_e.tab, gcar000b11m_e.tab
- Geography Markup Language (GML) file gcar000a11g_e.gml, gcar000b11g_e.gml
where "g" refers to geographic representation, "car" indicates that it is the census agricultural regions file, "000" is the three digit code identifying it as a national file, "a" indicates it is a digital boundary file while "b" indicates it is a cartographic boundary file, "11" is the date stamp for the year of release, "m" or "a" or "g" indicates the software and "e" or "f" indicates the language of the file.
