[OSM-talk] Bounding box

The amount of data returned through a bounding box depends on the density of
data on the map in the area.
Following analysis of DB queries, we now have the following limitations (some
tightened, some relaxed):
bbox for GPX or OSM data queries: 0.3 degrees squared
Maximum nodes for OSM queries: 50,000.
Previously, there was no bounding box limitation for GPX queries and there was
no node number limitation. However, the bbox for OSM queries was 0.06 degrees sq
so that has been relaxed substantially. These changes shouldn't affect most OSM
mappers, but will prevent newbies from tying up the database with damaging
queries they probably didn't mean to send.
With regards the timing out, I hope those problems have been fixed by the new
limits. The db load certainly appears much lighter, and the system should again
be providing excellent performance.
> Current bounding box of 2.5 K is pretty small and is timing out,
