   I have several lists of sampling locations in various flavors of lat-long.
I'll do the conversions first, then insert them in a separate postgres table
so they're available for all sampling data. Given the history of this
operation there are frequently slight differences between the geographic
coordinates recorded for water and biotic samples for the same station ID.
