Request for information - Ref No: FOI19878
Thank you for your email of 15 February 2019, requesting information from Ordnance Survey in accordance with the Freedom of Information Act (FOIA) 2000, as set out in the extract below:
This morning, 15th February an OS surveyor surveyed my property, xxxxxx Tile xxxxx and the accessible surrounds. This was at the request of the Land Registry.
Please could I have all raw data from this survey in DWG or DXF format, whichever is more convenient for the OS to provide.
I note that in Innes v Information Commissioner Lord Justice Underhill recognised the right of the applicant to request FOI data in a format of their choice for ease of manipulation. I further note that the Land Registry will not be able to provide this data, which has been a historic reason for such survey data to be withheld by the OS.
We assume that your request for ‘raw data’ is for the digital mapping data captured by our surveyor and updated to our database. Under section 16 of the FOIA, we can provide you with an extract of the updated mapping, direct from the database however, we do not hold the mapping in the format you have requested. Please see the attached map extract.
Please note the mapping extract provided is subject to crown copyright and database rights and is for information only, allowing you to see what changes have been made. Therefore, you may not reproduce, distribute or publish it without Ordnance Survey’s express permission. This restriction does not apply to reasonable use for your own non-commercial research purposes, private study, or any other uses permitted under the Copyright, Designs and Patents Act 1988.
We consider the mapping you have requested in the format you require to be exempt under section 21 (Information accessible by other means) because the information is intended for publication to our customers as part of our routine scheduled release of OS MasterMap Topography layer. Therefore, if you do still require the mapping in the format you have requested this should be reasonably accessible to you by contacting one of our licensed partners, as explained below:
When a survey is undertaken, any amendments which the surveyor makes to the Ordnance Survey mapping are saved into our database. The updated topographic detail will form part of the supply made available to HM Land Registry during the daily update and all customers of OS MasterMap Topography Layer.
Changes to OS MasterMap are extracted from the database approximately once every six weeks and published around two weeks after that. Following the surveyors visit to your property, the next scheduled release date will be 8th April 2019. Further details of our OS MasterMap data availability dates can be found here:- https://www.ordnancesurvey.co.uk/business-and-government/help-and-support/products/os-mastermap-refresh-dates.html
You therefore will be able to obtain a copy of the requested mapping information from one of our Licensed Partners after this date (8th April 2019). Please find contact details for some of these below, and they will be able to advise you on the mapping available, the formats and the costs involved.
Further contact details are available at the following link:-
We also consider the information to be exempt under and section 22 of the FOIA (information intended for future publication) although we are not relying on this exemption in this response.
On this occasion this request has been dealt with under the Freedom of Information Act 2000, requests for mapping are considered routine enquires and should normally be directed to our Customer Service Centre in the first instance.
Your enquiry has been processed according to the Freedom of Information Act (FOIA) 2000.
