Just added a number of footpaths that I had the pleasure to walk over the weekend in the Wye Valley area between Tintern and Chepstow. There's a reasonable amount of mapping data in this area already, but a lot of it seems to be from the NPE maps and either out of date or inaccurate. For example the boundaries of wooded areas don't match with what we found on the ground in all places. There's a lot more mapping that can be done in this area, including more paths, accurate outlines of woodland, disused railways, quarries and so forth. It's a beautiful area for walking in and quite easy to get lost in the woodlands - especially where there is a high density of paths going in different directions. Definitely warrants a return journey.
