Surely that can't be correct? For example, I've surveyed an awful lot of the Perth northern suburbs, but I started off by tracing Nearmap imagery. My understanding is that Nearmap haven't agreed to the new licensing but nevertheless I've since personally surveyed the streets, corrected alignments, added names and changed "source=nearmap" to "source=survey". I would understand if data and records of the original "source=nearmap" disappeared with the license change, but the subsequent "source=survey" edits would be able to be kept? Dropping data simply because at one time it was in an incompatible-license state but is now no longer sounds incredibly destructive to me. Is what's going to happen documented anywhere? I've had a poke around the wiki, but can't see anything relevant to how the data is being handled. -- Andrew
