[OSM-talk] Residential areas

[Dave]

I think smaller areas are probably better. Layering of landuse areas is
conceptually wrong -- it would mark areas as residential even though they
weren't: it might work on a particular renderer, but other applications
might not like it (ie: a program trying to calculate the area covered by
residential housing). The only time this would be right is where you
actually have one on top of the other... ie highstreet shops with flats on
top.
Also ways covering large areas are difficult to edit as data gets packed in
around them, plus I think the current API map algorithm might not return a
way if none of the points are in the area you request, as would happen with
a city wide area when looking at, say, just the centre.

Personally, doing mapping in London, I'd limit the area size to that bounded
by a main road, ie: a secondary or primary. It's completely arbitary, but
makes sense for the kinds of maps likely to be produced and isn't too fiddly
as marking in an area for every street would be. But again, I'd try and
avoid covering an area twice, so go round the edges of parks, sports fields,
commercial or retail districts etc.
TBH I'm still using abutters... can go back and fix them when I'm bored and
it's too cold or wet to collect new data.
