[mkgmap-dev] How to display administrative boundaries / shade them?

From Craig Durkin craigdurkin at gmail.com on Tue Jan 18 19:30:02 GMT 2022

That's what I would have thought too, but no luck. It seems like the
"polygons" file maybe only deals with closed ways and not specifically

For what it's worth, my program is invoked with:

java -jar mkgmap-r4586/mkgmap.jar --gmapsupp --gmapi --transparent
--output-dir=gmap_output --style-file=mkgmap-r4586/new_style/ data.osm

and the 'polygons' file in new_style/polygons has the following line in it:
boundary=administrative [0x07 resolution 20]

Hi Craig,

I think all you need is a rule in style file polygons to render the object.
