From James Associates:
Backpack, camp, and hike in the unspoiled wilderness of Crater Lake. Cross-country ski, sled, snowmobile, and ice fish in the higher elevations of Malheur Forest. With MacTopos, enjoy Oregon at its best! James Associates, producer of MacGPS Pro software, now offers MacTopos Oregon for the ultimate topographic digital map solution.
Two DVDs for Oregon 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 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 2700 detailed images on your hard drive, or use them directly from the DVD. Optimal quality maps create one great solution for the Mac outdoor enthusiast!
MacTopos 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 MacTopos maps. See where you're at, where you're going, and where you've been!
