This topic has come up a couple of times recently, so here are my instructions on how you can use Open Street Map as a layer in Radarbox. The instructions are in the attached OSM.PDF, and the spreadsheet referenced in the instructions is also attached as OSM.XLS.
It takes just a couple of minutes to replace a Satellite Layer with an OSM layer instead.
1. In Radarbox, setup the map to cover the area you’re interested in. Then, download a satellite layer, and save it. In this example, I'll use the saved name of "OSM1".
2. In Windows Explorer, navigate to the ... \AirNav Systems\AirNav RadarBox\Satellite\ folder.
3. Locate the OSM1.JPG file. Right click on it, and select PROPERTIES. In the DETAILS tab, make a note of the DIMENSIONS. In this example, it is WIDTH=861 : HEIGHT=895.
4. Locate the OSM1.STL file, and open it in Notepad. Select ALL the text (CTRL-A), and COPY (CTRL-C). Then close Notepad.
5. Open the OSM.XLS spreadsheet.
6. In cells C4-C7, paste the four numbers from OSM1.STL
7. In cells E9 and E10, type in the WIDTH and HEIGHT numbers previously obtained from the OSM1.JPG file.
8. Goto cell E19, and COPY (CTRL-C).
9. In Internet Explorer, goto the address bar, and PASTE (CTRL-V). Press ENTER. A map should appear. If that address doesn’t work, then try E21, then E23, then E25 until one of them works. Right click on the map, and select COPY.
10. Open the OSM1.JPG file in Paintbrush, and PASTE (CTRL-V) the new map. Save the OSM1.JPG file.
11. Back in Radarbox, reload the OSM1 map.
