Color WAPaprs maps are provided in three zoom levels: 500 feet, 2,500 feet, and 2 miles. They all have the same screen resolution (about 70 x 90 pixels). These color maps are GIF files that are not the standard format for WAP applications. As such, GIF images do not work on all portable devices (WBMP is the universally accepted format for mobile wireless devices). However, if you are fortunate enough to have a mobile device that supports color and GIF files, these pages are perfect. The display of a useful map is difficult given the display size of most devices. Nevertheless, they can still be very useful.
