Cartographic Boundary Files
are a series of products containing the boundaries of standard geographic
areas together with the shoreline around Canada and larger inland lakes,
all integrated in a single layer. (The lakes and shorelines are also referred
to as hydrography). The coordinates are latitude/longitude and are based
on the North American Datum of 1983 (NAD83).
The Cartographic Boundary
Files for 2001 replace the Digital Cartographic Files produced for the
1996 Census.
Cartographic Boundary Files
(CBF) were created to support the spatial analysis and thematic mapping
of data from the 2001Census of Population, where realistic shorelines are
required. They can also be used with Census of Agriculture or other Statistics
Canada data for data analysis and thematic mapping.
The Census Divisions and Census
Subdivisions Reference Map Series presents census divisions and census
subdivisions for all provinces and territories and also displays census
metropolitan areas and census agglomerations.
The maps are designed to enable
users to identify the relative location and boundaries of the geographic
areas reported in 2001 Census data publications and to visualise the relationships
of the geographic areas shown in the geographic hierarchy.
The Census Tract Reference
Maps, by Census Metropolitan Area or Census Agglomeration series presents
census tracts for census metropolitan areas and tracted census agglomerations.
Census tract names and boundaries are shown on all the maps.
There are 27 census metropolitan
areas and 113 census agglomerations defined for the 2001 Census. Census
tracts are defined for all of the census metropolitan areas and for 19
of the largest census agglomerations. The Census Tract Reference Maps,
by Census Metropolitan Area or Census Agglomeration depict the components
of the metropolitan hierarchy for those larger urban centres with census
tracts.
The maps are designed to help
the user identify the general location and limits of the geographic areas
used in the 2001 Census data publications.
The dissemination area reference
maps cover three distinct types of areas: census tracts within census metropolitan
areas (CMAs) and tracted census agglomerations (CAs); non-tracted CAs;
and census divisions outside of CMAs and CAs. All depict the dissemination
area as their smallest reference unit. In Canada, there are 52,993 dissemination
areas defined for the 2001 Census.
The maps are designed to enable
users to identify the general location and boundaries of the geographic
areas for which 2001 Census data are available.
The Road Network Files (RNFs)
are disseminated to provide geographic reference information for the 2001
Census data. They can be used to reference the boundaries of the geographic
areas by which Census data are tabulated or to request retrievals of census
data by user defined geographic areas.
Road Network Files contain
a road layer for the entire country and a province/territory boundary layer.
The road layer includes roads, with road names and address ranges (arc
attributes), and geographic codes to identify blocks, census subdivisions,
census metropolitan areas/census agglomerations, and provinces/territories
(polygon attributes). Address ranges are mainly available in the large
urban centres of Canada. The province/territory boundary layer incorporates
hydrography (the shoreline around Canada and the inland lakes and waterways)
with the boundaries and the geographic codes.
The Road Network Files are
released as a geographic reference for the 2001 Census data. The Road Network
Files, in conjunction with Statistics Canada data, can be used for applications
such as site location analysis, planning of service delivery or various
types of data analysis and mapping.
The Skeletal Road Network
File contains selected roads (with road names, but no addresses) that are
derived from the Road Network Files. The selected roads are ranked according
to four levels of detail. The different levels of detail are suitable for
mapping at small to medium scales.
The Skeletal Road Network Files can be used to provide some roads for cartographic
reference when producing thematic maps with the Cartographic Boundary Files.
Skeletal Road Network Files
provide full digital coverage for Canada. Back
