Contained within the Atlas of Canada's Reference Map Series, 1961 to 2010, is a map showing national, provincial and territorial boundaries. Data on the map sheet is restricted to populated places and drainage features. The very extensive set of populated places shows their population (using 1981 Census data). The drainage network corresponds to the ""full drainage"" network used for most National Atlas of Canada, 5th Edition maps. The Canadian land mass is in yellow with shaded relief being used as well. A notable feature is the use of shaded bathymetry.
