[Tagging] Difference between lighthouses and beacons

[Janko Mihelić]

A map with lighthouses was produced [1] that gained popularity because it
was nicely rendered, but it showed how flawed OSM data was in this regard.
Very often little beacons [2] are mapped as man_made=lighthouse, which is
not right. Lighthouses are big structures that were built to have living
quarters for people that operated them.

So a fuzzy rule can be created, you can't have a man_made=lighthouse tag
and seamark:xxx=yyy tags on the same object. That's instantly an error.
Seamark tags are used for instruments that help navigation, and lighthouses
are structures that can house those instruments. But they are not the same
thing. So a lighthouse can be an area with a seamark node at the place
where the light is.

Is this generally accepted?

Thanks,
Janko
