[mkgmap-dev] [PATCH v1] add close-gaps option to generate-sea

Wed Jan 20 01:11:49 GMT 2010

I don't understand why we still need 0x4b polygon in case of using 
--generate-sea=polygons if we have a polygons for land and one for see. 
Isn't this enough?

The problem is that 0x4b behaves a bit strange, so I would prefer to 
neither map sea, nor land to it as in that case flooding or land over 
sea may happen. I think some people simply replaced 0x4b by other 
polygon types. Maybe we would have less problems if when polygons is 
used, no 0x4b background polygon were generated.
