MacTopos Texas for Mac

From James Associates:

Cycle, 4-wheel, or hike the backcountry in Big Bend National Park. Horseback ride or mountain bike in Pedernales Falls State Park. With MacTopos, enjoy Texas at its best! James Associates, producer of MacGPS Pro software, now offers MacTopos Texas for the ultimate topographic digital map solution.

Three DVDs for Texas contain 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 maps 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 4559 detailed images on your hard drive, or use the maps directly from the DVD. Value-priced, optimal quality maps create one great solution for the Mac outdoor enthusiast!

MacTopos Texas are automatically georeferenced for James Associates' MacGPS Pro software (available separately) to 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 MacTopos maps. See where you're at, where you're going, and where you've been!
