Spent a bit of time tidying up what little mapping has been done so in Yeovil, Somerset (England) using NPE maps and local knowledge. Things including adding roundabouts, adding a number of one-way tags on dual-carriageways, correcting the direction of one-ways, addition of a few roads that are on NPE, correcting a few name errors where roads appear to have been (incorrectly) merged. To be honest though, this town of 35,000 is in desperate need of a mapping party! So much has changed since the NPE maps were produced that much of the layout is completely unrecognisable these days, and my tidy-ups were necessarily somewhat limited. Even getting accurate traces of the main features in the town centre would be a very useful improvement, let alone doing the residential roads in the suburbs.
