Hi, I've load from OSM rectangle bbox=24.061,35.2895,24.2976,35.4638 using Overpass API export. (this is part of Greece > Crete) There are among other things 2 polygons nature_reserve (140514809 and 140515050) and polygon natural water (356673828). I use the newest mkgmap 3909 (Windows 10). After using mkgmap with option file: family-name=fam-name-kreta gmapsupp output-dir=D:\Dokumenty\OSM\ttt\ description=descr-kreta unicode index route precomp-sea=C:\Users\Darek\Downloads\sea.zip generate-sea order-by-decreasing-area mapname: 63240001 input-file: map.osm After generating gmapsupp.img and transferring to Orgeon 650 unfortunately I don't see neither polygons (140514809 and 140515050) nor polygon (356673828). What I do wrong? Best Regards Dariusz Kwapisz
