Wrong route on roundabout
by Oskar Ohakas 30 May '24

30 May '24

Hello, I compiled my first gmapsupp.img and on test drive garmin offered an obviously wrong route on a roundabout (garmin.jpg). On OpenStreetMap i get the same wrong route with algorithm Car (Valhalla), but Bicycle (Valhalla) and other routing algorithms will give the correct route. https://www.openstreetmap.org/directions?engine=fossgis_valhalla_car&route=… I followed the instructions from https://wiki.openstreetmap.org/wiki/Mkgmap/help/How_to_create_a_map mkgmap \ --route \ --add-pois-to-areas \ --bounds=bounds \ --index \ --gmapsupp \ 6324*.osm.pbf Have I missed an important option? Is it possible to fix the problem in compilation phase or is it something confusing for Garmin algorithm in OpenStreetMap data? If it helps, then I have uploaded the gmapsupp.img for possible inspection to the address https://0x0.st/XNpC.img/gmapsupp.img Any helpful insights are welcome. Oskar Ohakas
