color=#0000ff size=2>There may be a misunderstanding here - the Definitive Map
is a legal document and was (in almost all cases produced a long time ago -
interesting thought in passing - if it is 50 years old would it be out of
copyright! The initiating legislation is the National Parks and Access to the
Countryside Act 1949 so some could be almost that old). Almost all Definitive
Maps are years earlier than GPS. The nice men from the council with cheap yellow
GPS units (they can't usually afford good ones) are surveying the paths with
respect to the definitive map to build a database on path condition to assist
their statutory duties of maintenance etc. and to cover their backsides in case
of legal action against them e.g if someone gets hurt on a path - this wonderful
litigious modern world!</FONT></SPAN></DIV>

just amending them from time to time in respect of a particular

of course is that they have a license to do what they like with OS data so
it largely doesn't matter to them whether they derive things from it (well
at least until they try and overlay that data on a google map and get
nastygrams from the OS). <BR><BR>Tom
