Three-quarters of the differences reported here are in the presence or absence
of a single apostrophe. This masks the more important discrepancies and makes
the report less useful.
Ed - I think specifically for Exeter as there are only 118 total differences if
the OS names are added where we don't have a name at all and any obvious typos
fixed then what is left (max 50?) could easily be surveyed in a couple of
trips.
Sure (if you accept that the street sign put up by the council is more
authoritative than the Ordnance Survey's database, which actually I doubt).
However, given only an hour or two to survey Exeter this weekend I would prefer
to concentrate on more important things than missing apostrophes. Others have
different priorities, of course.
For my own use I would prefer to see a report that flagged only the real
differences in name, ignoring punctuation. I expect some other mappers would
feel the same - while others might still prefer to flag every difference in
name,
no matter how small.
The ITO report is also useful for armchair mapping, adding names to roads that
lack them or fixing obvious and definite typos or spelling errors (but only when
you can be 100% sure the OSM data is a spelling mistake). Here too the
punctuation-only differences tend to crowd out the more important and more
easily fixable mismatches.
I map what's on the ground, apostrophes and all. The only way to do that
is to go and take a look. When I do I invariably find something else to
add or improve at the same time. So checking street names for
apostrophes, along with other different spellings or omissions always
seems productive to me. Ordnance survey certainly do make mistakes,
after all their data is gathered and processed by people. They
acknowledge their mistakes too - if you send them documented anomalies
they investigate them and correct accordingly, though it's not as quick
and easy as OSM.
