Hi Thorsten The obvious flag byte is src/uk/me/parabola/imgfmt/app/net/RoadDef.java: netFlags where the meaning of these bits is unknown: 0x80 0x08 0x04 - always set 0x01
There are other ways the Garmin IMG format uses to give meaning to things, eg ordering according to some type then, elsewhere, having a list of the offsets of where each type starts; I don't know if this is at all relevant in this case Ticker On Mon, 2025-02-24 at 13:46 +0100, Thorsten Kukuk via mkgmap-dev wrote: > Am 2025-02-20 11:50, schrieb Ticker Berkin via mkgmap-dev: > > Hi > > > > Not 100%, but pretty sure this flag affects routing.
