[Qgis-user] geocoding with own locator based on points

[Tobias Wendorff]

That's how I would do it. I've developed a geocoder for a customer once (before Nominatim had its current quality). It's a lot of work…

There is also a difference between type-in (online) geocoding and from-file (offline/batch) geocoding. In the first case, the user can see results and correct his typing. In the second case, the geocoder needs to have some kind of AI to provide the best match to the user (highest rating, find phonetic similarity etc)

You can contact me directly to write in German. We could provide the results or a summary to the list.

Unfortunately our administration requests the official data for the project (ALKIS). In addition I found some other tools related to different countries or regions (Netherlands, Poland, Russia…), but not Germany.
