Of course this is not the place for deciding for OSM at large. Note that
HOTOSM's mapping is well within the general OSM conventions - surely it is
decidable "it seems that both is possible, so we could choose either for
our purposes." As for differences between TI and wiki - yes, some
conventions
But you can't decide something about OSM on the HOT mailing list. You can
confer and edit the wiki but that may or may not be followed. There are a
number of instances where what is suggested in the wiki and taginfo are
quite different.
Data compression was mentioned purely because of the writer
Hello all,
There's really no "their" where OSM is concerned - the database is made by
individual contributors, without centralized oversight, and much of the
mapping is by convention. But looking at the OSM wiki gives some fairly
strong recommendations: http://wiki.openstreetmap.org/wiki/Key:build
But from your computer science background you should realise there are
costs involved. To mark a building as a node is one line in the database.
As a way well there are four nodes for a start each with its lat and long,
then you have the connecting way. Have you saved a bit of .OSM and opened
it
On personal level I feel mapping buildings as nodes is very wrong so I
avoid it.
But I think tagging nodes as building should be looked at very well. I will
recommend it is deprecated.
Best,

My opinion is that buildings should be mapped as areas.
In un-mapped areas it would be best to create landuse=residential areas
first rather than quickly tagging buildings with single nodes. When it
comes time to trace buildings it is troublesome to convert single nodes to
polygons.
For existing si
Dear both, dear all,
If we're agreed that it's better to map buildings as areas - should we try
to re-map node-buildings from previous campaigns as areas? Or shall we just
leave it?
Many thanks,
Bjoern

AFAIK Osmand renders addr: housenumber also for polygons [1].
Anyway I agree to the general rule that rendering has to adhere to mapping
(and not VS).

OpenStreetMap and HOT conventions are slightly different. In OpenStreetMap
a much wider range of mapping conventions are used and it is quite
acceptable for a building to be mapped as a node or outline, in HOT the
convention is to map it in outline.
If the buildings are mapped accurately then you
Dear all,
I've got a few questions about buildings and residential areas. Here's the
first one. Can buildings be entered as nodes? This may well have been
discussed before :) but I'd like to understand the situation better.
