[Talk-GB] Mapping Shropshire's rights of way

[Ben Proctor]

I'm not sure whether this is helpful but I wrote this earlier this year
with the help of the OS. It's an attempt to unpick some of the issues in
asking local authorities for mapping data.

Though we didn't have OSM contribution as a use case in mind when we wrote
it. I plan to revise it soon (this is rather overdue actually). Any
feedback that would make the next version helpful would be very gratefully
received.
