[mkgmap-dev] EU map too big?

Fri May 15 07:33:26 BST 2015

Hi Minko,

that' s good news :-)

When you reach the limit again you may have to remove some 
details from the overview map, e.g. use level 19/20 instead of 18
or remove the "background" type 0x10100.

I only see one potential improvement in the program: 
Many bytes are used to store sea / coastline polygons.
If we ever manage to find a better algo to simplify
them for the low Garmin resolutions we may be able
to store better info with fewer bytes. The current combination 
of filters tends to produce self-intersecting ugly 
looking triangles which often contain spikes, which means
they have redundant bytes.

@Mike Baggaley:
I think your pointInPolygon-v0.patch
showed a completely new approach to simplify polygons
using the Java Graphics2D.fillPolygon() method.
Maybe this could be used as a new filter for shapes
in MapBuilder. It seems to do exactly what we want.

Hi Gerd,
Probably something went wrong the first time. I now managed to produce a full map with all the tiles and mkgmap-r3595.
Thanks again for the quick fixes!
