[OSGeo-Discuss] Batch geocoding

Fri Feb 4 15:08:51 PST 2011

That is a nice trick, I will remember that. I really just need the
coordinates, since each coordinate needs to go back into a database in a
register of a location-time that needs more data added later. These are the
"generic" addresses, with the apartment numbers stripped, so each address
will provide coordinates for multiples DB entries on different dates, and I
won't really be using them on the same layer. But I am sure I can figure out
a way to get the data back out with PostGIS (the original data is in
Postgres anyway).

Cheers,
JP
