[OSM-talk] microsoft/BuildingFootprints

[john whelan]

I think the guidelines cover it nicely.  I'll sprinkle a few pointers
around.

I've found changeset comments don't work terribly well with HOT mappers.
By the time I stumble across a problem it's a year or more later and they
last mapped 9 months ago.

In theory they do have a validation process but in practice they have fewer
validators than they need.

The other problem is currently many have a comment saying Microsoft
buildingfootprints.  DWG them and the quick solution is to leave the
comment off.

It's a balance between adding a lot more buildings in and adding too many.
In some areas with few buildings they are useful.

With the new mapathon clean up tools in JOSM duplicate buildings aren't a
major problem and these buildings are a lot better than many drawn with ID
but an ounce of prevention saves a lot of clean up plus until it is cleaned
up it messes population estimates up.

Thank you for the pointer.
