Hi Gerd, I did a little more testing.
Is it possible that the presence of a complete address is the trigger ? I tried building maps with the Places POIS forĀ cities, towns and villages. It didn't help at all, search for POI is still slow. When I put the POIs for the fuell stations, the search is fast. The only difference, safe the type of course, is that the fuell stations usually have a complete postal address attched, while the city centers do not. Here's a sample for the map with the city POIS: |http://files.mkgmap.org.uk/download/482/POI_BAD_dach_boundary_gmapsupp.img||| Ciao, Franco Am 06.06.20 um 14:46 schrieb Gerd Petermann: > Hi Franco, > > one of my other ideas was a semi-transparent map where the transparent flag > is set but the 0x4b polygon is still added to the map. > Made no difference. > > Gerd > > ________________________________________ > Von: mkgmap-dev <mkgmap-dev-boun...@lists.mkgmap.org.uk> im Auftrag von > Franco Bez <franco....@web.de> > Gesendet: Samstag, 6.
