Offline data base possible ?

[intika]

Hello

First thanks for your amazing work !!!

I found that only official backend are working (from microg) all other alternatives does not seems to work.

Any way is it possible to use/create an offline data base like "LocalGsmNlpBackend" is supposed to do ?

Thanks

Online data can ensure data is up to date at any time，Offline data can't ensure this

Mozilla's database is proprietary. It cannot be downloaded. So no, it's not possible with this back-end.

Get https://f-droid.org/repository/browse/?fdid=org.openbmap.unifiedNlp It has the option to download an offline database. Use https://f-droid.org/repository/browse/?fdfilter=radiobeacon&fdid=org.openbmap to scan and contribute WiFi data.

That's wrong. The cell database is public domain and of course downloadable. Only the Wi-Fi database is not downloadable for privacy reasons.

This backend allows you to download MLS cell database and use it offline.

Yes, the GSM database is downloadable. But since it covers only cell towers, it's can also only offer very inaccurate location data. I understood the question as being about the whole database, not just the cell towers, considering it already mentioned LocalGsmNlpBackend.

This is not the place to discuss the reasons why Mozilla does not make the WiFi DB available. Fact is they don't do it, whereas Openbmap and OpenWiFi.su (aka OpenWLANMap) do and of those two only Openbmap has an actively developed NLP back-end.

Exactly. I also prefer to stay to the matter of fact way. I just wanted to correct the claim the database would be proprietary.

And for the TS I think the best way would be to use the other backend.
