What is Google Earth?
Check out http://earth.google.com:
The idea is simple. It's a globe that sits inside your PC. You point and zoom to anyplace on the planet that you want to explore. Satellite images and local facts zoom into view. Tap into Google search to show local points of interest and facts. Zoom to a specific address to check out an apartment or hotel. View driving directions and even fly along your route.
That by itself is fantastic, and the fact that it's free makes it even better. But why do we use it on TrailDamage.com?
You may have noticed that some trail pages have links to Google Earth Placemarks and Google Earth Tracks. This is additional information about this trail. After you install Google Earth and you've successfully connected to the Google servers (you can look up addresses and see maps, for example) you can click on any of these special TrailDamage.com links to get more trail information.
If you open or save the .kmz file you can use it in Google Earth. If you select "open" it will open Google Earth for you and zoom to that location. Placemarks are spots on the earth that you will zoom to, like trailheads, obstacles and other features worth mentioning.
Google Earth Tracks take that one step further. If you open a Track you can see the entire trail laid out on the earth. But that's not all you can do -- you can also instruct Google Earth to do a "flyover," letting you see the trail as it's run.
If you download and save the Placemarks first you'll be able to see them as you do your Track flyover. Enjoy!
