The Relationship Between the Large Scale DEFRA Map & Online Version
The DEFRA large scale map above clearly shows that the site is well
inside the flooded area and NOT as depicted in the DEFRA website map
as being opposite Crabtree Lane. The Internet DEFRA flood search maps
would be those that people would refer to when looking for a safe place to
live. Once you've found the page a search can made by entering a
post code or a town. It is a very good resource, but only if it is
Why is there an Error?
DEFRA's mapping facility is based on maps supplied by the Ordnance
Survey. Unfortunately it appears that the mapping was derived from
the 1:50,000 series maps. (refer to Flood Maps)
Rather than the 1:25,000 series. This makes no sense as surely the more
detailed mapping needs to be used to ensure a more accurate location of
the buildings. Someone made a serious mistake, as this type of error
must be happening on the mapping of the whole country.
The correspondence from the CEO of DEFRA and the Ordnance Survey
What was in the mind of the person who should have been studying this
map when it was being prepared, was it derived from film? Why hasn't it
been corrected? There are those that may say, my complaint has been lost.
Lost? I doubt it because I wrote directly to the Chief Executive Officers
of both DEFRA and the Ordnance Survey and received personal letters from
both CEO's so they believed that my complaint was sufficiently important
to write to me personally and I was also visited by two officers from
DEFRA later. The DEFRA map has been altered to show the legend: "Mill"
rather than as was previously labelled "wks" unfortunately the actual
location of the Freshford Mill has remained in the wrong place and is now
even more misleading!. Perhaps it is realised that the whole mapping that
has been prepared for DEFRA will need to be scrapped or removed from the
Internet and replaced by a more accurate tool.
The map that was used by the Environment Agency for the development of
the Flood map facility was the Ordnance Survey 1:50 000 scale 1991
edition. Earlier editions show Peridins and Freshford Mill almost
correctly for this scale of map .
