Online atlases vary widely in quality, but this latest project from the Royal Canadian Geographical Society is a laudable production both in terms of its organization and also its multi-layered content. This highly interactive atlas allows users to explore all of Canada's landforms and boundaries through a pop-up atlas browser that includes a sophisticated, yet easy-to-use, interface tool by which users can zoom in or out, measure distances, and even print out the maps they create. Some of the additional features let users explore the country thematically by region (such as the Boreal Shield) or by the dynamic theme of "Extremes of Weather". There is even a "Kid's Atlas", which is specifically designed for young people with the hope that they will also learn a great deal about Canadian places and geography. Much of the material on the site is also available in French.
