If so I'll try and write up some guidance in the wiki. > I do agree that raw water features from OS Vector District are pretty unsatisfactory and should be cleaned up. Personally I would prefer a single linear way for streams rather than the area 'river-bank' approach which the OS use, however the most important thing is for water features to be continuous under bridges. I support people putting guidance together but won't contribute myself to a great extent. On reflection possibly we should use river-bank as that has more information in it, but recommend that anyone importing does a 'bridge cleanup' at the same time.
