Hi everyone,
So if I understand correct most parking spaces are mapped as polygons?
yes
https://taginfo.openstreetmap.org/tags/amenity=parking_space
I don't see the problem to add a width and length tag to a
parking_space node,
there is no problem except to be aware that this is the least common
schema and the one that gives the least information, and that
therefore any contributor can convert a width=A length=B into a
surface object having this dimension and which will also give a
position of this object in relation to the others (does the parking
space touch the neighbouring parking_space, does it touch a kerb, etc)
because this is more detailed info about the dimensions of a parking
space,
that is actually measured by people on site with a measure tape.
the polygon data is not accurate enough to really use for our app.
I don't understand this argument despite the fact that to repeat it :
a node width=A length=B is not more precise than a polygon
with thoses dimensions
The polygon gives the orientation - could be parallel to the road or at
some angle.
I prefer the polygon, more trouble to map but you can use imagery to get
it.
Are there other apps that add info about parking places as polygons and
extract dimension info from the polygon data?
most map style, including osm-carto (the main style on osm.org)
