Record layouts and data descriptions

Agricultural ecumene mask file

The agricultural ecumene mask file contains polygons for each ecumene and non-ecumene pocket, which combined cover all of Canada.

Table 4.1 Agricultural ecumene mask file record layout

Census division generalized cartographic boundary file

The Census division generalized cartographic boundary file portrays the census division boundaries for which 2011 Census statistical data are disseminated. A census division is a unit of regional government (such as a county or regional district) or an area treated as equivalent for statistical purposes. A census division is usually made up of a number of adjacent census subdivisions (municipalities). The file contains the boundaries of all census divisions which combined cover all of Canada.

Province and Territory generalized cartographic boundary file

The Province and Territory generalized cartographic boundary file portrays the boundaries of the 10 provinces and 3 territories for which 2011 Census statistical data are disseminated. Provinces and territories are the major political (legislated) areas of Canada. The file contains the boundaries of all provinces and territories which combined cover all of Canada.

Hydrographic reference file

The supplementary hydrographic file is provided for the mapping of inland water. This file was created to be used as spatial reference in conjunction with the ecumene file to enable thematic mapping.

File extension and accented character information

The ArcGIS® , Geography Markup Language and MapInfo® 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.

Some files within this product contain attributes with accented characters. They were successfully tested on desktop versions of ArcGIS® 9.3.1 and MapInfo® 11.0.1.

Geographic representation

The Agricultural Ecumene Boundary File is available on the Statistics Canada website in the following geographic representation:

  • Datum:  NAD83
  • Coordinates:  Longitude and Latitude

The North American Datum of 1983 (NAD83) is an adjustment of the 1927 datum (NAD27) that reflects the higher accuracy of geodetic surveying.

The geographical coordinate system is the primary locational reference system for the Earth. This system provides for the unique statement of location for features such as points, lines and polygons.

Users of the Agricultural Ecumene Boundary File can transform the files into the representation that best satisfies their needs, knowing the effects these representations have on angles, areas, distances and direction. Users have the option to choose the best projection in concert with mapping objectives.

File naming convention

Spatial product file names follow a file naming convention. The 2011 Census standard geographic area and code, file type, geographic reference date, software type and language are embedded within the file name. Standardizing the names of the files facilitates the storage of compressed files, all having the extension .zip.

Each file name is 13 characters in length. All alphabetic characters are in lower case to maintain consistency.

First character: projection of file

  • g  projection is Geographic (latitude and longitude)

Next three characters: primary geographic level of file

  • pr_  province and territory
  • cd_  census division
  • eca  agricultural ecumene
  • hy_  supporting hydrography (Great Lakes, St. Lawrence River and a selection of inland lakes)

Next three numbers: geographic code of coverage

  • 000  Canada

Next character: file type

  • e  ecumene

Next two numbers: geographic reference date

The geographic reference date is a date determined by Statistics Canada for the purpose of finalizing the geographic framework for which 2011 Census statistical data are collected, tabulated and reported. For 2011 Census products, the geographic reference date is January 1, 2011.

  • 11  geographic reference date is 2011

Next character: file format

  • a  ArcGIS® (.shp)
  • g  Geography Markup Language (.gml)
  • m  MapInfo® (.tab)

Final two characters: language

  • _e  English
  • _f  French
