[Talk-GB] Ordnance Survey

I'm in line with this view too. We cannot assume that the OS mapping is
correct, it may or may not be current or accurate, so it's useful as a guide
in the absence of any other verification source.

Streetview as a product is still a long way short of the level of detail we
are routinely creating ourselves. The VetorMap District product that is
being released next month won't add that much either, yes we can map landuse
areas a bit better if there is no other source. We also noted that
residential streets are not named in VMD so like Y! imagery there is little
point in importing for unmapped areas unless someone is prepared to add the
street names from ground survey, or (second best) from OS Streetview, which
may or may not be accurate in terms of what is on the ground.

Please don't be fooled, the OS may be a great organisation and produces
great mapping that we have in the past relied upon for so many uses, but our
map is a pretty damn good product too and once verified in an particular
area is probably always going to be up to date and richer than any OS
OpenData product.
