[OSM-newbies] buildings as points and/or areas

[Robert Helvie]

Hi,

In some original ride-bys and surveys I marked the locations of some
supermarkets and such on OSM with just a single tagged node.

Now, after editing in some boundary streets and using yahoo's aerial imagery
I can go back and outline the larger supermarkets and tag them as named
buildings. Am I correct in assuming that I should now remove those original
nodes, or does it not matter if the node sits on top of the building? Or is
there some other way to do it. What is the common/accepted practice?

The thing I am wondering about is whether the areas (buildings) are (would
be) searchable on any OSM routing sites or when map data is transferred to
GPS units (Garmin, myself). Right now parks seem to make it to the Garmin,
but some other areas don't which means a supermarket as a building might not
show up without the node on top.
This isn't "tagging for the renderer" but rather tagging for the GPSr. Yes,
I know that really on the Garmin these things should actually be depicted
using type files, but sometimes that is rather difficult to accomplish, and
other times nearly impossible with the limited amount of types available.

Just looking for an answer and any input. Thanks a bunch.

Jama rek,

Robert
