[mkgmap-dev] Order of objects rendered

Thu Jan 28 01:40:32 GMT 2016

I saw a note on the tagging list just now that reflects on something I've
been curious about for some time. If mkgmap comes upon an object that has
two tags, both of which are valid, which one will mkgmap use? Here is the
post:

One of the rules we use is the "one feature, one OSM element” [1]
This makes sense for a lot of elements, e.g. if something has the tag:
higway=residential it would be silly to also have amenity=restaurant on the
same element.
But it is not very uncommon to have a memorial that was created as a piece
of art by an artist. One could tag such an object with:

tourism=artwork
historic=memorial

and of course add other relevant stuff like artist_name etc.

But what should be rendered in such a case? The memorial or the artwork?

>From my understanding, once a node or way with a valid code has been
encountered during style processing, mkgmap considers it finished and moves
to the next item. But let's say I prefer to see the historic=memoriaI tag
rendered and don't care about artwork, is there a way to prioritize the
assignment of icons to one of those tags?

Cheers,
Dave
