[Talk-GB] Impact of OS

[Andy Robinson]

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.

Cheers
Andy

Great. 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"
