OSM is a source of data for many maps, by many renderers which render
the data in many ways, of which mkgmap is only one.
Therefore we have a saying "Don't map to the renderer."- it's the
renderer's job to pick up and do the right thing.
I don't know mkgmap so I don't know what it does, but it it if happens
to be that mkgmap doesn't work this way, then we'd have to fix mkgmap.
But since this is so common, I'm fairly sure that it's fine and does
work.
to directly answer the question, mkgmap will produce POIs from buildings
with tags relating to POIs. i don't know what OsmAnd does, but i imagine
it's probably something correct. i'll be experimenting with OsmAnd next
month, i think.
Is it better to edit other peoples work only to
make things consistent (especially if there is a specific recommendation for
a way to do things), or better to respect the way they have done things and
leave inconsistencies in method as they are?
Consistent and correct is better. Maybe they didn't have time to add
it by anything but POI. You should feel free to improve upon the work.
older image sources may not have been very good for building outlines, we
have much better imagery now. improvement is always worthwhile.
