There's been an on-going question about whether it is legal to display data derived from Ordnance Survey licenced mapping via google maps.
By derived data, I mean geometries which have been copied exactly from, or are composed of parts from, another dataset.
The blog post here: http://blog.ordnancesurvey.co.uk/2010/08/what-the-psma-really-means/ outlines the issue.
We've spoken to Google and they say that the OS have recently relaxed their licencing, but haven't been able to get any comment from the OS. The last post on the OS blog is from November 2012.
Does anyone have any ideas as to how the land lies here? Particularly if anyone has heard anything from the OS on this subject since November 2012.
16th April 2013: We've got an account manager at the OS now and a collegue has just spoken to him. Long story short: nothing has changed since November 2012 - any data derived from OS licenced mapping which is not specifically "free" (such as OS OpenData) may not be displayed in Google maps. Our account manager didn't know when the OS was going to come back with an answer. He said he'd chase it up.
