Base Map Layers
- Atlas of Canada Framework Layers
- Base map components are features that provide a geographic
context for the thematic data shown on Atlas of Canada maps.
These features include rivers, lakes, administrative boundaries,
populated places, roads and rail lines. All of the Atlas of
Canada base map components are available for immediate free
download in five scales and in a number of data exchange formats.
The 1:7 500 000 and the 1:1 000 000 scale data are the primary base
frameworks used for all Atlas of Canada 6th Edition online
maps. You can download Atlas of Canada data from this Web
