[OSGeo-Discuss] Batch geocoding

[JP Glutting]

Thanks Pieter.

Geomajas looks very nice! I don't mind rolling my own, but this is just a
preliminary part of a big project (my Masters thesis), and I only need to
geocode the data once. You don't know of any code or solutions I could take
a look at that implement a solution like this?

Thanks,
JP
