From James Associates:
Camp, geocache, off-road, hike, bike, and ski Alberta, Canada in style. James Associates Inc., producer of MacGPS Pro software, now offers MacTopos Alberta for the ultimate topographic digital map solution.
Four DVDs for Alberta contain the entire province in two crystal-clear map scales: 1:50K, and 1:250K. New technology allows the same sharp detailed images as the original Digital Raster Graphics maps from Natural Resources Canada, except they are compressed to save space without losing resolution. Install any or all of these detailed maps on your hard drive, or use the maps directly from the DVD. Optimal quality maps create one great solution for the Mac outdoor enthusiast!
MacTopos Alberta works with James Associates' MacGPS Pro software (available separately) to automatically show your current position and velocity on the correct map in real time using most GPS receivers. If you have a supported Garmin or Magellan GPS receiver, you can also electronically transfer your Waypoints, Routes, and Tracklogs with a few clicks on these MacTopo maps. See where you're at, where you're going, and where you've been!
