It's worth considering the following;

   - CRT are using their own (high quality, high consistency) data. No need
   for OSM data.
   - OSM detail is highly variable, and parts of CRT's system might not be
   mapped at an appropriate level of detail or accuracy.
   - OSM tagging etc. is prone to change which would involve extra expense
   in tweaking the base cartography rules (see tagging discussion on
   lock_gates for an example which would affect canal cartography). (See also
   the discussion of pipeline tagging which directly affected client work of
   someone on this list).
   - OSM does not have the funds or people to offer either financial
   support or equivalent staff involvement which I imagine the partnership
   with Google involves.
   - OSM does not have the means to provide services and service delivery
   on knowable timescales and costs (for instance doing Streetview for
   - There is no OSM technology which a) matches GSVs capabilities; or b)
   can capture 360 degree panorama images quickly.
   - Integration of CRTs assets into a widely used search engine and
   familiar software (GMaps, GSV) is likely to bring tangible benefits to CRT
   far faster than using OSM. CRT needs to find new sources of funding, so
   this is a non-trivial issue.

Lamenting that CRT are not using OSM fails to recognise that OSM are not a
service provider. Equally, OSM data is not consistent enough to provide a
base layer for this kind of work. And finally, I imagine, this is done to
fairly fixed timescales: again something which OSM introduces
imponderables, aka unknowable risk factors.

Some of these things can be changed, but others represent things which just
are not part of OSM and are unlikely to be so in the foreseeable future.

I'm proud that we can be more accurate and up-to-date than Google Maps and
the Ordnance Survey, but I dont make the mistake of thinking that we are a
pure substitution play.
