Hi all,

while debugging the problem reported by Arndt Röhrig

http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2016q4/025471.html


I noticed that his style adds all polygons with "min resolution 10" like this:

landuse=basin [0x53 resolution 10]


Up to now I thought this is just causing more CPU load :

The polygon is processed for each (low) resolution  and after many calculations 
it is typically "thrown away" because it

is reduced to a single point in the


I think we can easily change mkgmap to calculate a proper "min res" value

for shapes depending on the actual size at resolution 24.

Probably that would also be useful for lines.


Any thoughts?


Gerd
