A popular feature of GPS2TurboCAD is the ability to view the imported points on free publicdomain aerial photos or topographic maps from Terraserver-usa. This lets the user doublecheck the data, and add new points as necessary. The maps are obtained automatically when the user clicks the "View Points" button, and then displayed in a separate window with the map, points and id clearly plotted. With one more click, the maps are sent into TurboCAD at the proper size and location for drafting!
