I have attached that patch to limit polygon creation to closed ways. It's untested and I assume there are some unwanted effects at tile borders. Please check and if you (and others) find it usefull it can be committed. WanMil
Moin,
I think the problem is not the multipolygon, but that some of the outer ways are tagged with surface=sand. These tags are not considered for the multipolygon, but for these ways mkgmap creates single surface=sand polygons.
But if you change your polygon style from
surface=sand [0x1b resolution 20]
to
surface=sand& natural!=coastline [0x1b resolution 20]
this shouldn't happen any more.
Just for a try: What happens, if you remove the surface=sand lines from your polygon styles completely?
And one other thing: There was once a patch, which limited the polygon creation to closed ways. Does anybody know, what happened to this patch? I really liked it.
