Hello all, I have the following rule in my polygons style: surface=sand [0x1b resolution 20] The problem is the following multipolygon: http://www.openstreetmap.org/browse/relation/1221199 This is a complex multipolygon which, in certain sections, uses the coastline to define the outer. Parts of the coastline (and therefore parts of the multipolygon) have the key/tag pair surface=sand The result is that mkgmap attempts to build a multipolygon for Port Philip Bay and fill it with sand, which is not ideal: http://www.cferrero.net/maps/img/1.png What I can't figure out is how to adjust my polygon style rules to avoid this happening. Or tell mkgmap not to process multipolygons of type natural=bay Neither of the following two variations of the rule makes any difference: surface=sand & natural!=coastline [0x1b resolution 20] surface=sand & type=!multipolygon [0x1b resolution 20] Nor does natural=coastline & surface=sand {delete surface} make any difference whether I put it in the lines file or the polygons file Does anyone have a suggestion on how to fix this? Thanks! -- Charlie
