Will be interesting to see what happens. Not sure what has happened to the dreaded 'derived data' clause in OS data, and how that will impact using newer OS maps.

Bradford centre is mapped, but the outer suburbs are not, so I think that might be a good place to cover. I have done a lot of mapping to the west of Wakefield, and have reached as far as Mirfield before the winter set in.
I can't make mapping party anytime soon, but can infill from Mirfield up towards Bradford as it's right at the edge of my range. Huddersfield is another big gap in mapping as well.
