How to use Google Earth to accurately display geocaches
Google Earth (www) is a powerful program that models the earth in 3D with arial or satellite photo overlays. It also can display things like roads, businesses, and driving directions. Additionally, if you download the "Google Earth KML" from your geocaching.com profile page (it's on the right-hand side column), you can view the approximate location of up to 150 geocaches at a time in your Google earth screen.
You may notice however that when you zoom in, the caches tend to jump about.
