[OSGeo-Discuss] Automatic geocoding of PDF documents

[Stark Hans-Jörg]

perhaps OpenAddresses (www.openaddresses.org) may also be helpful. it is far from being complete yet but for some regions the data is fairly dense (and if donated complete) - and: it provides geocoding as rest services (see the wiki).
