USAPhotoMaps enables you to automatically download USGS 1-meter and 8-meter aerial photos, and 4-meter topo maps from Microsoft's Terraserver Web site, and creates a contiguous map from them. You can scroll it, view it at 4 levels of magnification, mark waypoints, center the map on any waypoint or latitude/longitude, see the distance and direction to a waypoint, and see the current latitude/longitude. You can make as many maps as you want. If you have a GPS, you can see your current location (updated every second), and transfer waypoints, tracks and routes to/from it. New version has been changed to an installable version of USAPhotoMaps.
