[mkgmap-dev] New branch for default typ file

From Gerd Petermann gpetermann_muenchen at hotmail.com on Mon Dec 9 16:41:30 GMT 2019

Hi Nick,

I don't want to cut out islands from bay polygons, I thought about a proper typ for 0x3d which somehow marks "calmer water"
and a draw order that puts this above water and below any land type polygon.
Is that possible?

Gerd

Hi Gerd

Yes, I suppose so
