I'm currently figuring out how best to make my tool at http://robert.mathmos.net/osm/prow/progress/ scale to be able to include many more council areas, and be able to be kept up to date with as little manual effort as possible. I'm not completely there yet, but I'm getting close. I'm certainly willing to add more areas if people express an interest, provided the data is available, in a suitable format, and suitably licensed for use in OSM. For the format, my preferred option is to make use of the standard format available from http://www.rowmaps.com/ as that saves me having to parse different formats from each council. So the first thing is that the data needs to be in rowmaps. (There's one slight glitch that I need to know which district each parish is in, which isn't always available in the file, but I can probably work around this if/when necessary.) As for the licence, it needs to be compatible with OSM, which probably means it being the Open Government Licence (OGL) -- see also below. > Dave refers to the long list of other councils that have released row > information.

There's a list in the OSM wiki at https://wiki.openstreetmap.org/wiki/United_Kingdom_local_councils , although it's not necessarily up to date. > The information on rowmaps is not clear.

This wasn't quite compatible with OSM's ODbL licence. Although OS gave us special permission to make make use of their own OpenData in OSM, this didn't/couldn't extend to data licensed by third parties under the OS OpenData Licence. The good news is that OS have retired their custom licence, and now release their own data under the plain Open Government Licnce (which is OSM-compatible). They also allow/encourage Councils to release their own derived data (including Right of Way) under the OGL too. What is slightly less clear though is the status of data previously released by third parties under the OS OpenData Licence. OS say that as far as they're concerned anything where they mandated the OS OpenData Licence can now be released under the OGL. But I don't think that automatically makes third-party data re-usable under the OGL -- the third party who owns the data would have to explicitly agree to the re-licensing. You'll see that some of the data on RoW Maps is explicitly under the OGL, and some (including Lancashire at http://www.rowmaps.com/datasets/LA/ ) was originally OS OpenData Licence but includes the statement about OS changing to OGL. (There may be other options for licences too, but I haven't seen any.) I'd like to play it safe, and only promote the use of those datasets for mapping where I am certain that they're ok for use in OSM. So I'd therefore like to have an explicit statement from the Council that their data can be re-used under the OGL before I add it to my tool. So if you want to see the data for Lancashire in my tool, the main hurdle to overcome is to get explicit permission from the council to use their PRoW GIS data under the OGL. If you're willing to try to get that agreed, then that would be great. Some sort of public statement and publicly available download link for the shapefile/KML/mapinfo file would be best if they are amenable. A public request on WhatDoTheyKnow would also be fine, as would be getting them to add the data and a licence statement to https://data.gov.uk/ .
