The Digital Cartographic
Files are geographic boundary files for thematic mapping applications
used by Geographic Information Systems and mapping software
packages.
Each Digital Cartographic
File includes geostatistical area boundaries that have been
modified to follow shorelines and coastlines. In addition a
few major lakes are included in the files.
The Digital Cartographic
Files are packaged by type of geographic boundary (e.g.census
tracts) and coverage (e.g. Canada, province/territory, census
metropolitan area or census agglomeration).(source:Stats Canada,1991)
No Digital Cartographic
files were produced in 1986.
What's
New in the 1996 Digital Cartographic File
An Enumeration
Area Digital Cartographic File is available for the first time.
Digital Cartographic Files are generally consistent with each
other for standard levels of geography - in 1991, only Digital
Boundary Files were consistent. 1996 Digital Cartographic
Files now include a separate map layer featuring augmented coverage
of in-land lakes and rivers (as polygons).
A Digital Cartographic
File for Forward Sortation Areas reported by Census respondents
is available for the first time. Some
Digital Cartographic Files are available in two versions: one
adequate for small scale mapping of the country as a whole,
one appropriate for large scale mapping. All Digital Cartographic
files are consistent with Street Network Files (other geographic
products containing streets, railways, hydrography, and other
physical features, as well as feature names and street names).
A portion of the Digital Hydrographic Base Information for Canada
was provided by Geomatics Canada, Natural Resources Canada.
