Iagree; I think these problems are SMS problems, although seems like the initial
query should be able to exclude points without lat/long information.  We do need
to integrate Taxon in that we need to be able to pass the query results to them
for name resolution, then get their results back into Kepler.

Dan: I think Jianting and I are going to put some effort over the next couple of
months into the post-GARP part of the workflow (best subsets, etc).  If you
could send me whatever notes you took in Dec, I'd like to compare what he told
you to what he told us in Feb, so I can make sure we get it the way he wants it.
