[Stefan Keller]

>From the news: OKFN wrote "Ordnance Survey announced that their OS
OpenData Licence is to be replaced by the Open Government Licence
v3.0."

Commented by a blog post of the Open Data Institute:

Finally: "Ordnance Survey is announcing it will launch a world-leading
digital map as open data" (www.ordnancesurvey.co.uk); "OS OpenMap – a
new ‘street level’ vector dataset designed to be the most detailed
open data mapping product available, providing a backdrop for
integrating and visualising analytical data."

1. Is this "OS OpenMap" worldwide or UK bound?
2. How does this "world-leading" digital map look like (map style)?
3. And what does this mean to OSM?

Yours, S.
