The Owlshead GPS MapViewer utilizes the popular Google Maps user interface in which to display the Project's route data.  There is a good chance that you already know how to use Google Maps, and if not, you'll probably learn it quickly and find it easy to use.

• Using the Map Viewer you can zoom in and out, and move and scroll across the map.

• You can even street-level imagery by moving the "pegman" icon along streets and highways.

• You can also change the background to either:

— a base road map with streets and highways ("Map" tab)
— a base road map without streets and highways ("OwlsheadGPS" tab)
— a topographic map (under "Map" tab)
— satellite imagery ("Satellite" tab)

• If you wish to reset the map and return it to the default view, click the "Reset Map" link in left side menu.
