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

Tue Jan 18 20:39:28 GMT 2022

Oh interesting, I wonder what the size difference is. I just uploaded my
version of the relation to https://files.mkgmap.org.uk/detail/545 -- it's
159.499 bytes, but it looks complete to me: it has the relation tags with
member way references, the constituent nodes (with latitude/longitude), the
ways themselves with node references, and tags for everything.

I created it by running the following query on Overpass Turbo (
https://overpass-turbo.eu ):
rel(id: 119584);
out body;
>;
out skel qt;

Thanks!
Craig

Hi Craig,

it works for me when data.osm contains the complete relation. I just
downloaded just that relation with all its members in JOSM
and the file has 359.898 bytes.
What's the content of your data.osm?
Maybe upload it to https://files.mkgmap.org.uk/
