I wouldn't even call this hacky. Alignment of the NPE maps is a bit  
out because of the rough-and-ready method used to rectify them - but  
if you can overcome that (as you're doing by aligning with connecting  
GPXs), the base cartography is plenty good enough.

I'm hopefully that we'll be able to make a big dent in areas of rural  
Britain using a similar method.
