I am mapping Tokyo Dome City, which is a maze of overlapping amenities (an
amusement park on top of a shopping mall with a giant pedestrian area with
fountains and ramps, bridges, staircases everywhere). The current issue I am
investigating is how to map a large amount of shops onto a single building -
the LaQua mall there has over 50 or 60 shops, a spa, rollercoaster, ferris
wheel, and a few other odd things all stacked into 1/3 a city block.
I took a train to another part of Tokyo looking for a shop that was right there
in the mall I was in, because it wasn’t even in Google Maps. I want to add all
the shops of the malls I visit to OSM, but as I get closer to Tokyo, the malls
get taller and taller ( 0101 at Kita-senju station is 9 floors of 100 shops or
so in 100x100m), and the new Lumine mall is directly over Kitasenju’s 4
combined stations), which would lead to an unfathomable amount of tag rendering
pollution, so…
a) is there a best practice to arrange all the point tags for the shops placed
on/in the Mall polygon?
b) indicating floor level in the mall is useful, and looking at the wiki shows
that the tag addr:floor=* is suggested - but it only has 158 uses - which is
amazingly small. is this the right key to indicate what floor a shop is on?
From my brief reading of the wiki some time ago ... level= is much more popular.
My primary problem with this is that some buildings will have their own way of
identifying the particular floor .. that will not conform to OSM tags ..
there needs to be a way of relating the local building floor names with the OSM
tag !
And the tags need to be able to use the local name directly - making the
mappers and checkers job easy - as the floor you are on is called the local
name ..not some OSM name that has to be looked up each time.
Good Luck .. I too would like to see some clear documentation and thinking on
this.
