For those who don't live on Twitter:

The UK Government has just announced its decision on freeing Ordnance 
Survey data. Full document is at 
http://www.communities.gov.uk/documents/corporate/pdf/1528263.pdf

Quick summary of what'll be released:

- medium-resolution vector data (Meridian2), includes street geometries 
and names though the curves are a bit angular: see 
http://www.ordnancesurvey.co.uk/oswebsite/products/meridian2/
- another new vector dataset called OS VectorMap District, scope as yet 
unknown
- StreetView raster data (includes street names, building outlines)
- postcodes, though with points ("unit centres") not areas (Code-Point Open)
- administrative boundaries (Boundary-Line)
- gazetteer (OS Locator)
- terrain data (Land-Form PANORAMA)
- a couple of negligible very small-scale maps

Contrary to original proposal, Landranger and Explorer rasters 
(1:25k/1:50k) will not be included.

Data available tomorrow (Thursday) at 
http://www.ordnancesurvey.co.uk/opendata .

Licence will be "without restrictions on use and re-use". Original 
proposal was CC-BY. The response notes that several respondees (many of 
whom read this list, I suspect) suggested either pure PD or the ODC 
licences because of the database rights issue, but doesn't actually say 
what the licence will be.

I'm sure there are a few other things we'd have liked to have seen 
(aerial imagery, for example) but on balance this is a great result IMO 
- and one that wouldn't have happened without OSM.

Suggest follow-ups to talk-gb.

cheers
Richard
