Tours And Travels In Delhi

Twenty years ago, when I was planning to hike the 3,000-mile Continental Divide from Mexico to Canada, I needed to purchase topographic maps. That meant tracking down map numbers, prices, and availability. Because I was creating my own route, I needed more than 100 detailed maps from the United States Geological Survey (U..S.G.S.) and the U.S.D.A. Forest Service. It was an enormous undertaking.

Today’s traveler has a whole other collection of resources available. Digital maps are available, and can be downloaded onto computers, cellphones, i-devices, GPS units, and other PDAs. Digital maps can even be customized, and you can print them on durable waterproof paper (Check out National Geographic's Adventure Paper; 15 sheets costs $19.95.)

Before you decide on which software to buy, consider your destination, how detailed you need the maps to be (you don't need as much detail on well-marked trails), and, of course, your budget.
