[mkgmap-dev] [PATCH v1] sea polygons

Sat Aug 1 22:10:51 BST 2009

Hi,

the attached patch adds a sea polygon  (based on the bounding box of the 
map) and a multipolygon relation with all lines tagged as 
natural=coastline as inner elements. The code merges coastline 
components as far as possible.
The patch also contains the multipolygon patch by Rudi which wasn't 
commited so far (without this patch, the rendering fails).

The sea polygon is created as "natural=sea", for which I added a mapping 
to garmin type 0x32.

Caveat: I have only tested this for islands (Corsica) so far.

Best wishes
Christian
