Explorer Map 276 Byrom Woods

Request For Information - FOI17796


Thank you for your original email of 6 November 2017, requesting information from Ordnance Survey in accordance with the Freedom of Information Act (FOIA) 2000, and your additional email of 21 November 2017, in reply to our response, clarifying your request. The text of your original email, our response, and your additional email are reproduced below for ease of reference.

Request email on 6 November 2017
On my OS explorer map 276 1:25 000 scale, 61 by 98 includes an area called Byrom Woods behind Byrom Hall. This map is Edition A1 Revised with selected change 2004.

The request is this.

This map was altered to take out the majority of Byrom Woods. Apart from the fact the map doesn’t now represent the physical reality of the area, who or what authority asked you to alter the map?

OS response on 21 November 2017
You have requested information regarding ‘who or what authority asked you to alter the map’. Explorer Map 276 has been checked as far back as 2000, and Byrom Woods has never been shown on Explorer Map 276. As such, the map has not been altered to ‘take out the majority of Byrom Woods’ therefore we do not hold the information you have requested.

We appreciate that our response contradicts your request, so if you are able to provide us with a copy of your Explorer Map 276, showing the relevant area, we may be able to resolve any misunderstanding.

Request email on 21 November 2017
If you compare the physical map you sell, you will see it has changed. Why did you change it?

Our response

The only change to Explorer Map 276 to the area you refer to in your original email, is in relation to CRoW (Countryside and Rights of Way Act 2000) Access land. CRoW Access land is designated as such by the Forestry Commission, and is displayed on Explorer Maps as a yellow tint surrounded by an orange border. CRoW Access land, in the area you refer to in your request, was shown on Explorer Map 276 in 2004, edition A1; this was then subsequently removed from Explorer Map 276 in 2015.

Ordnance Survey does not hold information relating to why the map was changed in 2015, in relation to the deletion of the Access land. We do not hold an archive of why changes such as deletions of features are made.

Ordnance Survey reviews Forestry Commission data on an 18- to 24-month cycle. The available data is downloaded from the Forestry Commission website, and our mapping is updated accordingly. If any areas are highlighted for change in between this time period, this will be investigated on an ad-hoc basis. To be clear, the latest available data from Forestry Commission shows the relevant area as still being CRoW Access land, and for that reason we assume that it was removed in error.

If this is not the change you are referring to in your request then please do provide us with a copy of your plan, showing the relevant area and provide a full explanation of the change you are referring to as previously requested.

I can confirm that our online map (OS Maps) now correctly shows the area you refer to classified as Woodland and Access Land. Ordnance Survey will ensure these updates will be shown on Explorer Map 276 when it is next due for revision. Please note we currently do not have a scheduled revision date for Explorer Map 276.
