This is why we should submit through the Atlas. From our recent Outback
trip I put in a "general interest" report to Birding-aus, while one of the
others in our group is submitting a number of GPS-referenced Atlas reports.

An interesting comment from the article about online databases:
"Surprisingly, records from website trip reports were even less well
georeferenced than museum records. We strongly recommend that authors who
intend their observations to be of practical use to others carry a GPS and
include co-ordinates as well as fuller descriptions of their bird-watching
localities."
Data's not much use if no one can tell where it was collected. There are, of
course, other ways of getting coordinates than using a GPS, Google Maps
probably being the next easiest.
