The bounding boxes (from EPSG) are in our database (at projfinder) and the SQL
query checks the map center point against those boxes to then only do the
distance calculation against those valid candidates.

That's great news, thanks.
All the best.

Thanks Aaron for this. IMHO an even better option would be to
explicitly add to EPSG/proj.4 db the bounding boxes of validity for
each projection: in this way, client GIS could show only valid
projections for a given map area, and this would be a

We played with something just like this last year (called projfinder):

map where you think your data is from, enter in a sample X,Y from your dataset
and it tries to guess what projection your
