Subsequent to the [recent consultation on Ordnance Survey data](http://blog.okfn.org/2010/03/15/response-to-the-consultation-on-opening-access-to-ordnance-survey-data/) and [Gordon Brown’s commitment to opening up (an unspecified amount of) the data in a speech last week](http://blog.okfn.org/2010/03/22/great-news-for-open-government-data-in-the-uk/) – today the UK’s mapping agency is releasing a significant portion of their data for free use by the public.
More information is available in [the following report](http://www.communities.gov.uk/publications/corporate/ordnancesurveyconresponse), published yesterday by Communities and Local Government:
The datasets which have been opened up include:
* OS Street View
* 1: 50 000 Gazetteer
* 1: 250 000 Colour Raster
* OS Locator
* Code-Point Open
* Meridian 2
* OS VectorMap District (available in May 2010)
* Land-Form PANORAMA
We’re glad to see that it looks like the data will be available under an open license:
> this licence will allow the data to be used and re-used for free by the public, including for commercial use. (p. 17)
The [official link to the data on their website](https://www.ordnancesurvey.co.uk/opendatadownload/products.html) has been overwhelmed all morning (which surely says something about public demand!). Some downloads are available from mySociety at:
Big kudos to [the folk at Ernest Marples](http://ernestmarples.com/blog/2010/03/government-response-to-ordnance-survey-consultation-published/), who did a great job in encouraging people to respond to the consultation and facilitated nearly a third of submissions through their online tool.

This is excellent news – and we very much look forward to learning more about the details as they unfold. We sincerely hope (given the date) that its not an elaborate joke!
