Request for information – FOI13377

Thank you for your e-mail of 17 May 2013, requesting information from Ordnance Survey in accordance with the Freedom of Information Act (FOIA) 2000.

Ordnance Survey does hold the information you have requested, and we respond to each of your points as follows:

'Upon enquiring with your Customer services unit today, I was informed that the border between xxxxxx was changed on 28 November 2011. The border line has been under dispute since December 2010.'

1. What was the source and upon who's authority was the request made to amend the map? It is recognised that the line does not represent borders but is trying to accurately reflect features on the ground? It could not be over flight as features obscured from the air.

The information we hold on the boundary feature indicates an alteration was made by a Land Registry field surveyor, from a ground survey, in November 2011. This would indicate a Land Registry case.

Under our duty to provide advice and assistance (Section 16 of the FOIA) we advise that we do not hold information relating to the source of this query leading to a Land Registry job being created, nor do we hold information to advise why a Land Registry surveyor visited this area.

2. We were informed by customer services that it is your policy to remove garages from your maps.

Changes are made to our mapping in accordance with our basic scales revision, and we advise that it is not Ordnance Survey's current revision policy to remove all garages from our mapping.

Garages and extensions to residential dwellings come under category ‘C’ changes according to our basic scales revision. Currently we do not capture or correct category C changes in either rural or urban areas.

However, Category C changes are eventually captured through a programme that is integrated with the capture of OS MasterMap® Imagery layer. The current revision cycle varies between two and four years. At present, extensions to private houses are not part of this programme.

Further information relating to revision and categories can be found on our basic scale revision policy web page.

a. why, when our demolished garage was removed (marked in red), was our extension (marked in green) not added as a true reflection of features on the ground at the time of amendment to the map? Can you arrange this now as the matter is likely to reach the courts?

Your extension has not been added to our mapping as it is not Ordnance Survey's current basic scales revision to map extensions to existing private residential dwellings, as detailed above in our response to your question 2.

Your demolished garage may have been removed because the basic scale revision differed in the past, or because it had been captured in the revision cycle also detailed above in our response to your question 2.

b. why was our neighbour's garage (marked x) not removed from the map, when it is your policy to do so?

The garage of number xxx is still in existence and this is correctly depicted. Please see our response to your point 2 about removal of garages from mapping.

The garage may have been captured for our mapping at a time when the property was a new build and this would have been categorised differently, or when the garage met our previous basic scales revision which may have differed.

As all the requested information has been provided, we have determined that in all the circumstances of this case the Public interest consideration (section 17 FOIA) is not applicable in this instance.
