![]() The first step when converting a paper map to a digital map is to scan the map and turn it into a graphics file. If you’re not technically inclined or are somewhat impatient, you’ll probably want to stick to importing maps that are already georeferenced, such as freely available United States Geological Survey (USGS) DRG topographic maps. Some maps are definitely easier to calibrate than others. ![]() Scanning and calibrating your own maps can be fairly time consuming and sometimes frustrating if you can’t seem to get the map coordinates to match up with reality. The following sections explore the above three steps in further detail. Load the edited map into OziExplorer and associate georeferenced data with the map image. Make changes to the scanned map before it’s used. Stitch individual map pieces, if necessary. Use a scanner to create a digital image of the paper map. ![]() This means if you have a paper map, you can scan it, load it into OziExplorer, and effectively make it an electronic (digital) map. ![]() But one of the program’s most powerful features is its ability to turn your own graphics files into georeferenced maps. OziExplorer supports a number of different digital map types that use georef-erenced data (information that allows a program to precisely identify locations and coordinates on a map).
