Interesting. Under what license to you believe East Riding issued the data that ROWmaps is using?

The actual page at the rowmaps site is:

http://www.rowmaps.com/datasets/EY/


It seems to say (and I'm paraphrasing) "ERYC say it's Crown Copyright, but the OS say 'All data exempted by Ordnance Survey is now covered by the Open Government Licence (OGL)' [but they don't say what data is exempted]" and then says "So it's possible for you to use this data provided you say that it is public sector information released by the council of East Riding of Yorkshire under the Open Government Licence".

I'm not convinced it's possible to infer the one from the other without much more detail than is on that page. That doesn't mean that somewhere those details don't exist - it just means that I wouldn't add data from rowmaps to OSM without more licence details.

However, to answer the original question:

1) Yes, some local authorities have made explicit releases of genuinely open data.

2) If if they haven't, and rights-of-way maps are encumbered by other licences, the council's "definitive statement" may well be admissable (something like "FP123 starts at the junction of X road and Y road and runs across the field to the gate at the north of Z house").

Best Regards,

Andy
