Hello,

old ssid locations move on the map when better localization in dbm field strength ?

WiGLE uses all observations of a network to try to figure out a likely location. See "How does triangulation work?" on the faq:

Thanks,

are already registered SSID in the map calculated again ?

(sorry my English )

Yes, every network (BSSID) in a new upload is recalculated.
