Hi all,

I think this is a good spot to put this thread to rest. We've answered the
question at hand and have since strayed a bit off topic.

We need to be able to distinguish between the object no longer being present, 
and the object still being present but its usage having changed.  If it is 
likely to be of historical and/or landmark interest, tagging both the 
historical name and current name is useful.

All gnis objects that are "(historical)" are no longer present and

yes, and no, we do store in small niches also historic information in the
main project, e.g. with the tags start_date and end_date, with the tag
old_name and variants of this tag, with the disused and abandoned tags etc.
A former school might also be an actual object, i.e. you might be able on
the ground to see that there is a school which is closed (hence
amenity=school doesn't fit, but disused:amenity=school or building=school
could be accurate descriptions of what is on the ground). To decide you
will have to know the area where you are mapping, deducting this from the
name tag of an import is most likely not very "ground-truthy" I agree.

Ok Serge,thanks for the encouragement!

I have seen schools in the middle of the forrest in a natural park so chances 
are big there never
was a school at that location at all . Ever. :)

We don't store historical information in OSM. There are other projects
which do, but OSM looks at what's currently in the ground. Also, gnis
tags are notiously wrong by large distances, sometimes up to 1km.

They're a classic example of the kind of data that, once imported,
people are afraif to touch. I had to explain to a mapper recently who
knew that a school wasn't present where the map said it was, that it
was allright to delete it.

He'd been to the location himself and found out that it wasn't a
school at all, but it was a drug rehab center! Despite having been
there and knowing this, he was afraid of "messing up the import".
This was an OSMer who'se been an active contributor for years.

This is why imports can have "dangerous side effects".

I would only delete it if there is no building at all. Agree that it is not
an "amenity", but if a building is errected as school it will somehow be
recognizable (often) as such, i.e. the building type is still "school" even
if there is no school there (unless the building underwent heavy
restructuring / modifications).

they shouldn't be tagged as amenity=school if they aren't currently used as
school, and the name-tag shouldn't contain descriptions like
"(historical)". There are several possibilities to deal with this, probably
also depending on the situation (e.g. how long it is that there was an
actual school).

On way is to use prefixes, e.g.
disused:amenity=school

or abandoned:amenity=school
etc.

this is preferable over adding a attribute like disused=yes as the latter
would provoke misinterpretations (if you don't search for these status
attributes), a risk that is circumvented with the prefix.

Another way is to simply tag the building as what it is and don't use any
amenity at all, e.g.
building=school (= this is a building of the building type school)
name=* (should be the name of the building in this case, as name always
refers to where it is attached to)
etc.

you can of course also use historic=school but I would personally prefer
one of the two ways described above, the first for not so long closed
schools and the second for the rest.

Martin

[Talk-us] historic schools (amenity=school; name= * (historical)

2014-03-04 Thread Theodin
Hi fellow mappers,

While doing some TIGER cleanup, I often stumble over historical schools tagged 
as:
amenity=school
name=some small town school (historical)

which are rendered on the map with their name. Are there any ideas for a better 
tagging as most of
them (all?) arent really schools any more.
I tagged some as
historic=school
which was in the database 80 times. Any better ideas?
