Prosurv LLC Releases SD Quads: Topographic Maps and Software for Windows on SD Cards

May 20, 2011


Prosurv LLC Software Company has released SD Quads, a new software and topographic maps package on SD cards for Windows Netbooks, Laptops, and PCs. Each 8GB or 16GB SD card (depending on the state) is pre-burned with every 1:24,000 scale (7.5 minute Quadrangle), 1:100,000 scale, and 1:250,000 scale topographic map for that state.  Each map is a 100 percent USGS digital topographic map, and each card contains up to 2,000 digital topographic maps covering the entire state.

Each card also contains a full installation version of SD Quads software. When coupled with a GPS receiver, it automatically loads and stitches the maps together as the user walks, hikes, bikes, or drives.  SD Quads eliminates the need to pre-upload maps, the company said. Scales can be switched on the fly.

The full-size quadrangle map can be viewed at any time by clicking on the map. Other features are pan/zoom, record and navigate to waypoints, record and playback routes, or attaching images to waypoints. The SD Quads software has automated stitching of maps, while at the same time allowing users to view and save individual quad maps with the collar information intact.
