Re: [mkgmap-dev] Multipolygons and disappearing coastlines

So, is putting the coastline into a multipolygon a reasonable OSM thing?

A coastline is often also a boundary and boundaries are multipolygons in OSM.

If so, should mkgmap be breaking the coastline by removing its tags? If not, how do we fix that?

My guess is, that the multipolygon handling in mkgmap is not working perfectly. See an older thread on this list where I suggest a workaround. (I check if the MP has no inner elements and change the type=multipolygon to type=boundarypolygon if this is the case). Chris
