It was a frustrating situation -- that is, until recently, when I learned of Canada's GeoGratis map service. In the past, this service only provided mapping data for high-end software unavailable at the consumer level, but it is now possible to download a high-resolution TIFF of any original topographical map. The interface is a rather confusing one, and it's easy to be disappointed if you try searching for geographical features. However, if you simply go directly to the topographical map key, known as the CanMatrix, you can move, zoom, and finally click on any map in the entire grid. A few menus and a download of about 30 MB later, you'll be unzipping yourself a full, 55-60 MB topographic map, which you can zoom in on, edit, and use to your heart's content. The small sample above, which shows the Royal Geographical Society Islands -- one site of the current search by Parks Canada, is from map 67d, "Cape Felix," a stunning 1:250,000 scale topo map with a remarkable level of detail. What's more, there's a surprisingly open-ended license for these materials, which apparently allows all kinds of use, including the making of derivative products. It's one of the most generous licenses for official governmental maps of which I'm aware.
So drop on by -- you will be amazed by the level of detail that's available! It's a Franklin-ophile's cartographic dream come true.
