Hi Gerd,
I tried to set a value in relations, but it applies to the ways defining the
polygon and not the polygon itself (so not visible in polygons file)
I also found that mkgmap:admin_level2 is null in relations so it wouldn't work
anyway.
I found a "workaround" that works for Croatia because the "ISO3166-2" tag is
set for counties in OSM :)
boundary=administrative & admin_level=6 & name=* & ISO3166-2 ~ 'HR-.*'
{ set mkgmap:label:1='${name}' } [0x16 resolution 14]

Hi Ranko,
1) type=boundary relations are not kept complete by splitter unless you set
corresponding options. Incomplete relations have rather unpredictable shapes.
2) the tag mkgmap:admin_level2 is set by the LocationHook. This calculates the
center of the polygon and looks up the tags for that point. If the center is
not inside the polygon this will fail.
There is a rule in relations which adds tag mkgmap:boundary_name. No idea if
this can be used in polygons, it is used in lines to render the borders.

Betreff: [mkgmap-dev] using mkgmap:admin_level2 in polygons
Hi,
I wanted to "display" counties using invisible polygons (so names are displayed
when hovering in BC or GPSr).
It is a multi-country map and county definitions differ from country to country
so I tried using mkgmap:country (mkgmap:admin_level2).
In the style manual mkgmap:admin_level2 is defined as "Name of the
boundary=administrative relation/polygon with admin_level=2 the element is located
in"
However, when I used the following rule in my style polygons file some counties
were skipped:
mkgmap:admin_level2=HRV & boundary=administrative & admin_level=6 & name=*
[0x16 resolution 14]
Using echotags I found that mkgmap:admin_level2 was set.
However, some of the counties had it set to neighbouring country codes (SVN,
BIH, SRB) and didn't pass.
Example county:
https://www.openstreetmap.org/relation/226749
Actually, splitter splits the map into more then one tile, so the county gets
split too.
In some of the tiles mkgmap:admin_level2 gets set to HRV (as expected), but in
others it is set to BIH
I used the latest bounds file (20210212) and a custom OSM-map area, but the
same happened when testing with croatia-latest.osm.pbf
What am I missing?
regards,
Ranko
