A Major Free Triton Map Source
Since its launch the Magellan Triton series was provided with access to National Geographic's TOPO! series of 1:24,000 scale topogrpahic maps. These maps are available for all US states.Through this alliance of Magellan and National Geographic, the Triton series is the first outdoor handheld whose users can download the National Geographic topographic maps. Although these are paid resources, they are not very expensive. To get an access to free Magellan Triton 200 maps you need to find other sources.
The Vantage Point software supplied with units in this series allows you to manage what you can get out of the devices. Based on a PC this lets you acquire maps, tracks, and way-points to share them with friends. You can, of course, download maps into the devices themselves. But, is there a way of acquiring the topographic maps for free? The only free Magellan Triton 200 map resource the devices come with, is the map of Yosemite National Park.
The USGS is the biggest source of maps in the USA. They have 1:100,000 and 1: 24,000 topographic maps of the complete country. These will also be the most authentic data of all such available data. On the negative side though, they will not have any interesting side information such as POIs as the Natgeo map series will have. Via the MapFinder service of the USGS you can obtain these maps. MapFinder™ for Google Earth is a searchable USGS topographic map index. It utilizes the basemap information from Google Earth data. The map Finder will help you locate details such as the section number, the vintage, and contour intervals related to the map and will let you download it for free.This application is available through the DDS, Inc.
