From James Associates:

Backpack, hike, and camp in the summer splendor of the Black Hills. Enjoy snowmobiling and snowshoeing in a winter wonderland adventure. With MacTopos, enjoy South Dakota at its best! James Associates, producer of MacGPS Pro software, now offers MacTopos South Dakota for the ultimate topographic digital map solution.

One DVD for South Dakota contains USGS topo maps for the entire state in three crystal-clear map scales: 1:24K, 1:100K, and 1:250K, plus US Forest Service 1:24K maps and digital elevation data. New technology allows the same sharp detailed images as the original Digital Raster Graphics maps from the United States Geological Survey, except they are compressed to save space without losing resolution. Install any or all of these 1720 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 South Dakota work 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!
