Dead Man’s Hill (SE 056 783)
There has been a Summit Relocation to a hill that is listed in the The 500-Metre Tops of England and Wales, with the summit height, col height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

Trimble GeoXH 6000: 545.161m at SE 05813 78297
LIDAR summit: 545.405m at SE 05674 78329
LIDAR close to Trimble set-up position: 545.267m at SE 05791 78308
The LIDAR result comes within the parameters of the Summit Relocations used within this page heading, these parameters are:
The term Summit Relocations applies when the high point of the hill is found to be positioned; in a different field, to a different feature such as in a conifer plantation, within a different map contour, to a different point where a number of potential summit positions are within close proximity, when natural ground or the natural and intact summit of a hill is confirmed compared to a higher point such as a raised field boundary or covered reservoir that is judged to be 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 545.4m and this is positioned at SE 05674 78329, this position is not given a spot height on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map, and is positioned approximately 150 metres westward from where the originally listed summit is positioned.
