Betchcott Hill (SO 421
982)
There has been confirmation of a Summit Relocation
to a hill that is listed in the The Fours
– The 400m Hills of England, with the summit height, col height and their
locations, the drop and status of the hill derived from LIDAR analysis
conducted by Myrddyn Phillips.

The criteria for the list that this summit
relocation applies to are:
|
The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams |
The name the hill is listed by is Betchcott Hill,
and it is adjoined to the Stiperstones
group of hills, which are situated in the county of Shropshire
close to the Welsh border, and it is
positioned encircled by minor roads, with the A488 road farther to its
north-west and the A49 road farther to its east, and has the town of Church
Stretton towards the south-east.
When the 1st edition of the The Fours was published by Europeaklist
in December 2013, this hill was listed with 20m of drop and with a 414m summit
height based on the spot height that appears on the contemporary Ordnance
Survey 1:25,000 Explorer map and which is positioned at SO 420 982. When the 2nd edition of the The Fours – The 400m Hills of England was
published by Mapping Mountains Publications in April 2018, this hill had been surveyed
with the Trimble GeoXH 6000, resulting in a 414.3m summit height positioned at
SO 420 982.

However, it was not until LIDAR became available that the details for the summit of this hill could be accurately re-assessed. The LIDAR (Light Detection & Ranging) technique produced highly accurate height data that is now freely available for much of England and Wales.

The raised field boundary on the summit of Betchcott Hill |
LIDAR analysis gives the highest ground on this hill as 414.3m positioned at SO 42097 98234. However, this is a part of a raised field boundary and protocols dictate that as this is deemed a relatively recent man-made construct such ground is discounted from the height of a hill.

The height produced by LIDAR analysis to the
natural summit of this hill is 414.2m positioned at SO 42106 98231, and this
position in relation to the raised field boundary comes within the parameters of
the Summit Relocations used within this page heading, these parameters are:
The term Summit Relocations applies to when the
high point is positioned in a different field, to a different feature such as a
conifer plantation, within a different map contour, a different point where a
number of potential summit positions are within close proximity, when natural
ground or the natural and intact summit is confirmed compared to a higher point
such as a raised field boundary or covered reservoir that is considered a
relatively recent man-made construct, or a relocation of approximately 100
metres or more in distance from either the position of a map spot height or
from where the summit of the hill was previously thought to exist.
Therefore, the summit
height produced by LIDAR analysis is 414.2m and this is positioned at SO 42106 98231. This
position is close to where the 414m summit spot height appears on the
contemporary Ordnance Survey 1:25,000 Explorer map and is approximately 9
metres eastward from the high point of the raised field boundary.
