i recognized broken coastline errors between the mkgmap verion 1188 and 1398. Please refer to the appended jpegs (my coastline is a little bit thicker ti identify the sea area).
Hi Michael, I can confirm that this problem exists in the newer versions of mkgmap. Some coastlines are missing in the map.
Dunno if this has something to do with the changes in the multipolygon code.
After playing a little bit with the data, I think it is the MP code thats causing the coastline to disappear. It seems that the error occurs, when a coastline is member of to many boundary-multipolygons. In my test the coastline was disappearing when beeing member of more than two boundary-MPs. So as a workaround: I think for boundary-multipolygons the multi-MP handling is not neccecary at all, because boundaries (normally) are rendered as lines and not as areas. Chris
