Black Hills Ghost Town & Ghost Mine Maps
by Dale Baiety
This DVD-R "data" disk contains topographical maps and aerial photo images that cover the Black Hills of South Dakota from north of Spearfish, SD, to near the South Dakota/Nebraska border. The east to west map coverage spans from east of Rapid City to the Wyoming border.
365,420 aerial photo images create a seamless mosaic that zooms from 64-meter to 1-meter resolution. 27.760 topographical map segments allow zooming from 32-meter to 4-meter resolution. The cursor shows latitude/longitude information for any location. Waypoint overlays identify 386 Black Hills ghost/historic towns and 999 Black Hills ghost mines.
A GPS is not needed to use the maps, but if the user does have a GPS, the included USAPhotoMaps program allows transfer of data in/out of Windows based computers. A laptop computer will supply real time on screen tracking of most GPS units. A Windows computer system with DVD-R "data" drove amd 2.4 Gig of hard drive space is required to install the program on your computer.
