<br></div>I haven't looked in detail, but basic use of buffers seems to grab most matching footpaths (buffer OSM data, and then use the buffered data to clip the DCC PRoW data).

I'm trying to make use of the row files on rowmaps for derbyshire and staffordshire and and merging these with and osm map file to then produce maps that can highlight which paths are and aren't mapped.<br>

Thanks for doing this.<br>
<br>
One suggestion - it would be great if the disgnation=public_footpath/<u></u>bridleway<br>
tags on existing paths could be tidied up at the same time. Last time I looked,<br>
too few had these tags to be able to use them exclusively to identify footpaths,<br>
and the other tag combinations tend to have many false positives.<br>
<br>
<br>
