The Atlas of Canada Base Maps
Entry ID: CANEMRCCRSDIGITALATLAS

[ Update this Record ]

Summary

Abstract: The Atlas of Canada Base Maps provide coverage of the entire Canadian landmass.
Data elements are feature coded and structurally clean. Base map components are
available in five scales and a number of data exchange formats. The 1:2 million
and 1:7.5 million scales are the primary bases for all Atlas products. The 1:30
million scale data have been generalized from the two larger scales.

The data set covers: drainage (coastlines, rivers, lakes), boundaries (federal,
provincial, district, dividing lines), transportation (primary and secondary
highways, selected ferry routes, rail networks), populated places, national
parks.

Atlas information is two-dimensional layered vector data. Access to information
regarding these datasets and the capability to download images and data files,
free of charge, is available through http://geogratis.cgdi.gc.ca/geogratis/en/index.html set of
base maps was originally prepared in an analogue form for the production of the
National Atlas 5th edition. They were used to overlay the thematic information
used in the preparation of Atlas maps. The digital versions were derived from
the original paper base maps in order to complete the 5th edition of the
National Atlas.
