Use the OpenStreetMap web site to create and download your map (https://www.openstreetmap.org).

Once on the OpenStreetMap site as shown in Figure: OpenStreetMap Website, follow the instructions provided by OpenStreetMaps to download a map.

When you open OpenStreetMap in Mobile InterferenceHunter software, a dialog box prompts you to enter the city and country. Then, the map is converted to the Mobile InterferenceHunter format and opened in the software. The converted files are saved so that when you open that location in the future, no additional formatting is needed.

To open existing maps, navigate to the directory on your tablet/laptop where the maps are stored and open any SHP file for your map. See Figure: Open Source Maps where 'roads.shp' is highlighted in yellow for illustration. InterferenceHunter will use all of the map files in the directory for the various map layers.
