This page is intended to be a guide to introduce new users to World Wind. It is not a complete guide by any means, and will not help you with any problems you encounter. If you do encounter any problems, or just want troubleshooting information, try the Frequently Asked Questions. If you want a more complete guide, look at the User's Guide or Introduction to World Wind.


First, double-click the "World Wind 1.3" icon, presumably on your desktop:


After the splash screen comes up (a whitish box with clouds) the main World Wind window should come up. At the top will be a toolbar:

There should be a small black arrow above the NLT Landsat button. Now, zoom in by either rolling your mouse wheel away from you (toward the earth) or holding both mouse buttons and moving your mouse away from you. Zoom into the San Francisco Bay area for this example. Stop at about 10000 meters. This is a good time to mention your location identifier. In the upper-left corner of your screen is a button:

If you don't see a bunch of numbers on the upper-right side of your window, click the button to get them. This information tells you where you are in the world. Towards the middlish bottom is your altitude, which should now be around 10000.

As you wait, you should see the world getting more colorful. Once these patches of earth (called "tiles") download, you can tilt the earth to see it in three dimensions. First, you'll want to make sure vertical exaggeration is on. On the menu bar, select "View->Vertical Exaggeration" and set it to somewhere around 2, which seems to be a good value. Setting it higher or lower will make the mountains steeper or less steep. Now, hold down the right button while moving your mouse around (move it down, for example). You can zoom in and move around all you want to see the terrain. Looking east, you can see mountains. Now that we've seen the 3-D aspect, press the spacebar once (not twice!) to get back to looking straight down. If you like, you can turn the 3-D off by setting vertical exaggeration to 0. Now, zoom in farther, to about 1000 meters.
