[mkgmap-dev] Load custom polygons to Garmin GPS using ogr2osm and mkgmap

Hi everybody, i'm trying to load custom polygons to Garmin GPS using ogr2osm and mkgmap. The problem is that i can't see my polygons on the GPS maps. However, everything is OK with a downloaded OSM file. Here is the script i use : python ogr2osm/ogr2osm.py polygons-4326.mif bzip2 -k -f polygons-4326.osm # wget http://download.geofabrik.de/osm/europe/france/guyane.osm.bz2 python pyMkgmapGarmin/pyMkgmapGarmin.py \ polygons-4326.osm.bz2 guyane.osm.bz2 Does anybody know why ? Thanks in advance, Regards Adrien
