Topographic maps are vital components to many outdoor activities. Knowledge of the landscape can assist with choosing portage routes, selecting promising hunting grounds or even identifying the best spots to set up camp.
One of my favourite sources for topography maps is the Atlas of Canada‘s data delivery system Toporama (and not just beacuase I am a sucker for a good online mapping program!).
Toporama provides 5m topographic contours for all of Canada overlaying some decent base mapping layers. Although other more detailed sources are available, not many are available online or are this easy to use. As an added bonus, Toporama also includes some pretty comprehensive base mapping layers ranging from from road networks all the way to wetlands and almost everything in between.
