[OSM-talk] Breach of Copyright?

[Barnett, Phillip]

+1
The 'definitive statement' is the only thing from the local authority that we can really use, but that is surprisingly detailed. Here's an example of a path modification in Cambridgeshire
"The above Order made on 30 May 2006, if confirmed as made, will modify the
Definitive Map and Statement for the area by adding to them two public footpaths.
The first (No. 26) starts on the southern side of Stetchworth Road, passes through
a field gate at Ordnance Survey Grid Reference TL6340 5783 (point A) and runs as
a grassed path in a southerly direction on the eastern side of a mature hedge for
approximately 283m to OS GR TL6344 5755 (point B), then turns to run in a
westerly direction for approximately 220m as a grassed path on the southern side
of a ditch and hedge to join Public Footpath No.6, Dullingham through a field gate
at OS GR TL6323 5752 (point C). The width is 2m from A-B and 1m from B-C.
The second (No. 27) starts at a point on Public Footpath No.26 Dullingham at OS
GR TL6344 5755 (point B), and runs through a field gate, continuing as a grass
path in an easterly, southerly and then easterly direction for approximately 320m
around the western and southern edges of the properties at Dullingham Ley to join
Ley Road at OS GR TL6370 5749 (point D). The width is 1m.

It does seem that what is needed here is not the definitive map but rather the survey data the two surveyors gathered. As others have said if that data has been overlain onto an OS map there is no way of knowing what is derived and what is not. Not unless the bod from the council is prepared to stick their neck out and confirm otherwise. As a result the OS would take issue because their data forms part of the definitive map.

Cheers

Andy

The map he sent is titled as a Definitive Map. It has an OS underlay,
but the information laid on top is compiled from Council gathered info.
eg GPS survey equipment from an independent company employed to produce
the definitive maps.

Do you know for absolute certainty that every single detail was gathered from first principles like that? If it was then it is a very unusual bit of local council mapping as they are not generally that scrupulously careful...
Well... not every detail, no, but there was a report in the local newspaper:
"Two surveyors will be walking virtually every one of the 560 miles of footpath in the area."
And also in the Council produced pamphlet where two people were shown holding their very nice big yellow GPS units.

Isn't every council having to do the same to produce their Definitive Maps?

The reason 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).
