Geographical Maps are usually more sophisticated than E-maps. These maps may provide more functionality. The actual background map can be any file including CAD drawings, AVI, bit maps, screen captures and the often used Google Earth map. Just use the Print Screen key to capture any image and save it to Paint (print screen is a one page buffer that is overwritten each time you press the print screen key). In Paint, select edit, paste to show the image. Crop and Save it to a folder.
