Thank you Nigel for your answer.
Hmm… I see the complexity (historical place names, translation, defining of areas using coords …) and I haven’t seen a convincing approach at all. In my point of view geotagging entrapped many genealogists to deform their place data by “normalizing”.
As a newbie it’s sometimes hard to figure out if something is not working well because of my ignorance or a half-baked module 🙂
