Contained within the Atlas of Canada's Reference Map Series, 1961 to 2010, is the latest version of a regularly-updated map of the National Atlas of Canada Base Map Series. Each version shows the World at an equatorial scale of 1: 35 000 000. The map is a general reference sheet focusing on showing the name and status of all sovereign countries and dependencies, and showing major cities. The 2005 version has two new additions: one is showing shaded relief for land areas; the other is showing bathymetric contours and colours for all marine areas.
