Hi everyone, The styles I am using add polygons to every building on the map. I never thought it was a problem, but recently someone did a mass import of all the buildings in my city and I started to get performance problems during GPS use. I want to avoid the polygons on the map, but I don't want to miss the POIs. I had partial success editing the polygon style file and removing this line: |# building tag should be last #(building=* | amenity=*) & area!=no & amenity!=grave_yard [0x13 resolution 24]| I believe this removes all buildings for which there's no other rule converting it to a POI. Can I remove all the other building polys too, since I am using the --add-pois-to-areas option, or I this will discard all the POIs? Thanks in advance, Alexandre de Menezes
