Not necessarily. With merging the polygons I meant to merge *what you actually see* on the map. That is also what makes it so hard, because the polygons will have no common points or even a common border, it just happens that they will overlap when displayed at a certain resolution. > Seems, we need a complete new concept in handling polygons and > multipolygons. Maybe we need to rasterize the OSM polygons to a bitmap and then create the Garmin polygons from that? Would be lots of work though (programming and computing/memory wise)...
