Perhaps in the authority you (appear to) work for. Most local
authorities that I work with (and I work with a lot of them) don't have
a GIS department, but if they do it consists of maybe one or two people.

The majority of street gazetteers that I am supplied with are appalling
in terms of quality, quite often with coordinates that don't match up
with OS Mastermap or Landline data.

Local authorities may well be responsible for maintaining lists of
properties, in the form of a gazetteer, but none that I have come across
are responsible for creating the geographic base data in the first place.

Yes. This is one of the issues I have to deal with. Many councils will
"get around" this by supplying us with their own, internally managed,
yet inaccurate databases. The shear amount of documentation that we have
to sign each year just to get hold of the Mastermap data with which we
create their maps is a ridiculous waste of paper!
