This set of base maps was originally prepared in an analogue form for the production of the National Atlas 5th edition. They were used as base maps to overlay the thematic information used in the preparation of Atlas maps. The digital versions were derived from the original base maps in order to complete the 5th edition of the National Atlas. They are the official bases used by the Atlas of Canada for the production of all their maps.
