This seems ridiculous but that is their answer.
I suspect that producing the Green Space map was forced upon OS by politicians, so they've just taken whatever existing datasets they have, and looked for polygon features that map to "Green Space" and exported them. (Hence the odd choice to include Golf Courses, which are mostly private.) Around me, the OS Green Space coverage is particularly poor with a lot of the public green space in my town missing. Much of the missing land in the town is owned by the District Council, but there are also bits that are CRoW Access Land and registered commons, which I'd have thought OS should know about. And then there's the whole of Thetford Forest missing! > I think it still has some value as it stands. Definitively. I've already found a couple of play areas hidden in housing estates that I didn't know existed, that I'll need to go a survey. The killer feature would be doing a comparison with the OSM data and showing discrepancies -- though that's much easier said than done! > Any more feedback will always be welcome. Would you consider adding the CRoW Access Land as an additional layer? (You can get the data under the OGL from http://environment.data.gov.uk/ds/catalogue/#/catalogue under the heading "CRoW Act 2000 - Access Layer". If you're interested in adding even more datasets, the National Trust has OGL data of it's "always open" land at http://uk-nationaltrust.opendata.arcgis.com/datasets/202ec400dfe9471aaf257e4b6c956394_0 , and the Forestry Commission make their Public Forest Estate boundaries available under the OGL at http://data-forestry.opendata.arcgis.com/datasets/national-forest-estate-legal-boundary-england-2016/ and/or http://data-forestry.opendata.arcgis.com/datasets/national-forest-estate-ownership-england-2016 (though there isn't public access to all of it). In both of these datasets there will be overlap with the CRoW Access Land.
