I would have thought that those counties with the fewest mappers should have benefitted the most from OS/BING data since more armchair mapping opportunities.
Extracting the data from the historical Planet files each week over time since the availability of these additional resources would permit analysis of how data addition changed. However you can't be sure from what source data was added (source tags would only give a clue at best) so might only be indicative. Trawl the OSM wiki, mailing list archives and the web generally for ideas on how to extract data and run analysis.

Two questions (since I'm new to the GB group) - anecdotally, what counties do you think benefited a lot from the OS data? what about Bing? where there particular regions it was especially useful for? - any pointers to tutorials on building an ITO style over-time visualization? What is easiest source if I'm looking for a history dataset for a small region. That would allow me to answer a question like "what was the impact of OS" Abhishek ------------ http://abhishek.mit.edu On Sat, Oct 19, 2013 at 4:49 AM, Andy Robinson <[email protected]> wrote: > I'm not aware of any study on this aspect but it's clear that each > time there is a major new source of open data that those who > contribute a lot get spurned on to contribute more (that is spend more > time mapping).
