Questions relating to a personal address and surrounding properties

FOI14597(2) – Request for information


Thank you for your email of 23 November 2015, clarifying the following questions from your first request of the 19 September from Ordnance Survey in accordance with the Freedom of Information Act FOIA 2000:

I would like to ask a number of questions under the Freedom of Information Act 2000. These questions relate to my home at XXXXXXXXX XXXX XXX, XXXX and the surrounding properties.

3. How is a decision made as to where a boundary line is placed on your MasterMap and Addressbase series of maps when no physical feature shows up, shows inconsistency or cannot be determined from your aerial survey pictures? Bearing in mind that your maps appear to always depict boundary lines.

5. Do you impose conditions on the use of mapping data supplied to Registers of Scotland when you supply OS data to them? (For example that as per the Ordnance Survey Act 1841, your maps may not be used to determine boundaries between adjacent properties. Or is there any other condition or restriction as to their use by Registers of Scotland imposed by you at the point of their use?).

Our response

I can confirm that Ordnance Survey does not hold the information you have requested. However, under our duty to provide advice and assistance as stipulated in Section 16 of the FOIA, we can provide the following explanation which may assist you in this matter.

3. Using the phraseology boundary line is misleading, Ordnance Survey (OS) does not depict boundary lines between properties, only physical features.

In some cases a vegetation limit if there is a change or difference in land cover or an inferred polygon closing link may be used to break up polygons.

Any decision will be made in accordance with the scale of capture and the specification in place at the time the survey took place.

5. Registers of Scotland (RoS) are supplied with Ordnance Survey (OS) mapping. As far as OS is aware RoS can then depict land titles how they so wish. The title deed RoS use is not “OS mapping” as such.

I hope the above is useful to you and clarifies the answers to your questions.
