This is a viewer for the Top 10 Most Visited National Parks in the United States. Five bonus parks are included as well.


Here are several things to try with this application:

  1. Double-click to zoom in, double-right-click to zoom out. Drag to pan.

  2. If you click on any of the 15 maps, you will see it appear on the globe. Some of the maps are small (example: Gettysburg, Pennsylvania), so you may need to zoom in a bit to find it.

  3. The maps are overlaid on top of aerial photos of the world taken by satellite. You can use the slider to turn the maps various shades of transparent. Or, find a spot on the map, then click the check box again to turn the map off, and then you can see what is on the ground at that location.

  4. If you hold down the shift key as you pan, you can tilt the map and see terrain. For example, zoom in on Rocky Mountain Nation Park, use shift-drag to tilt the map, and you can create views like this, where the map is overlaid on terrain:

  5. If you ever get lost, simply refresh the page to reset.

    Web page performance will decline if many maps are visible simultaneously. This web page is not recommended for mobile devices.
