[Tagging] Feature Proposal - RFC - Tennis wall

[Michele Galimberti]

Greetings Bert, thank you for your comments.

This is my first proposal in Openstreetmap, so I'm sorry if I didn't use
some of the best practices about mapping with nodes. I can only say that I
tried to get all the info I needed before I created it, and I certainly
didn't want to trigger anyone. Could you explain to me what is the problem
with my wording? I think that many features in the wiki have an indication
similar to mine, in which the choice is left to the mapper regarding
whether to use an area or a node. I'm of course open to changing or
removing that part if it's not following the community best practices.

You don't say anything about mapping the wall itself, within the pitch. How

I'm really not sure on that one, I have found no good solution to indicate
the wall position. The solution that seemed less bad to me was to have a
tag to specify which segment (or segments, as circular walls exist) of the
area have the wall but I didn't really like it. Another possibility would
be to use a multipolygon for the pitch in order to split it in ways and tag
one of them with barrier=wall. Ultimately I decided to leave it out of the
proposal as I didn't consider the side where the wall lies really important
from a mapping point of view.

What about mobile walls ? What about pitches with mixed use ?

If I understand correctly, you mean some sort of wall that can be moved and
goes on a normal tennis pitch. In that case, I would map the pitch as a
normal tennis pitch and avoid mapping the wall at all, as it's not a
permanent feature on the terrain. If, however, this wall is practically
always on the same position the pitch could be mapped as two
practice_pitch, both with tennis=wall, as they would be two de facto
separated pitches usable only for training.

Mixed use poses indeed a problem. Personally I haven't seen a tennis wall
sharing the space with another pitch, but I imagine it would only take a
part of, say, a basket pitch, so I'd use two areas that partially overlap.
I didn't consider the problem before now though.

Greetings
