MacGPS, which has been a Mac OS X native application since November 2002, was recently updated to version 5.0 by developer James Associates. It works with all handheld and fixed-mount Garmin and Magellan GPS receivers and can upload and download waypoints, routes, tracklogs, and GPS satellite almanacs. You can use it to import and use a wide variety of maps, including marine charts, from all over the world, or use maps you’ve scanned in yourself.
Version 5.0 works with marine charts in NOS/GEO and BSB versions 1, 2, and 3, converts directions generated by the Maps On Us Web site to uploadable routes, imports GPX waypoint files from the GPS-based treasure hunt Web site Geocaching.com, displays USGS topographical map names for any location in the U.S., and shows date, time, and elevation for clicked-on track points.
System requirements call for Mac OS X v.10.2 “Jaguar” or higher. A Classic version of MacGPS runs on Mac OS 6.0.7 through 9.2.2. Pricing is US$39.95 for delivery by email or $49.95 on CD-ROM.
