Using the Map Exercises

Minimum System Requirements This site uses the latest technologies to present large, interactive maps to you with a minimum of download time. Despite the size of some of these maps (due to the breadth and depth of information available), each map has been streamlined and resources are shared between maps to make your viewing experience as productive as possible. To accomplish this effectively, the following technologies are required:

Supported Browsers This site will work in most versions of the popular browsers. While we encourage you to use the latest browsers, as a general rule, PC users may use Microsoft Internet Explorer 3.01 and later, Netscape Navigator 2.0 and later, and AOL 3.0 and later. Due to a significant limitation in Microsoft's implementation of JavaScript, Macintosh users must use Netscape Navigator. Neither the Mac Internet Explorer nor AOL will properly display these files.

MacroMedia Shockwave for Flash

Flash is used to show you high-quality, scalable maps. Netscape users require the Flash 4 plug-in, while Microsoft Internet Explorer users on the Windows platform require the ActiveX control. Both versions can be downloaded for free from Macromedia. If you do not have Flash, you will not be able to use any of the interactive maps. IMPORTANT NOTE: If you have an earlier version of Flash, you may be able to see an incomplete map with limited functionality. If you notice that a map does not have a title, or some of the buttons don't appear to work when you expect them to, check which version of Flash you are using. One quick way to do this is to right-mouse-click (for Windows users) or Control-click (for Macintosh users) on the map. A limited navigation menu will appear at your mouse position. At the bottom of the menu, a "Using Flash x" option will appear, revealing your version number.
