![]() ![]() ![]() Mkgmap will not process arbitrarily large input files, so you probably need to cut the osm file into smaller chunks, most easily with the new splitter. You should probably use Mkgmap or GroundTruth for this. Convert to IMG file: You need to convert the.Split large area: If your area is a big region or a whole country before compiling OSM data to a garmin IMG file you need to split it with : Splitter.If you are writing software, download through the XAPI.For a command-line download, see Getting Data or GroundTruth For Dummies#Downloading OSM Data.(But note that this is inefficient for large data sets, as JOSM will attempt to draw the data, which can take many minutes, and which you don't need to do if you're only trying to use the data on a GPS unit.)

It can also generate relief contours from SRTM data for Garmin maps. It has a wiki-based rule engine for specifying how map features should look like (which it then uses to generate Garmin TYP files).
