Hi Thomas,
okay, I'll dig into this during the next days. My understanding so far is that the ovm_*.img tiles do not contain 0x4a polygons and that the code adds just one 0x4a polygon for the overview map. Maybe this is split into pieces because some size limits are reached...

No error mesasage ! Maybee a error message prevent mkgmap to create the _mdr.ing. I use a workaround with cgpsmapper to create the preview.img. I am angry, that my workaround wil lnot longer work, if mkgamp gives me error message.thank you. thomas by the way... : the problem is: mkgmap creates many 0x4a for one maptile. it should creates only one 0x4a with the tile-boundaries, like in the corrresponding tdb. Maybee is the solution, to use the same algorythmus for writing 0x4a in preview like in tdb ? Am 01.07.2016 um 10:57 schrieb Gerd Petermann: > Hi, > > I am back from a nice cycle trip to Sicilia.
