Estimated Class 3, fails Class 1 and 2 on unstable and unnatural ground cover outside of 10 metres, for Class 2: “Ground covered with natural and low vegetation (<10 cm) representative of the region;” Farmed crops and ploughed fields will not do. The height of the crops varies and very likely exceeds 100mm sometimes. Oilseed rape is showing (http://www.sac.ac.uk/directory_record/3194/winter_oilseed_rape)
UHI, local, road, stone wall, distance, none.
This site provides an opportunity to see one type of equipment cabinet when weathered and once again the paving. Perhaps that is a single slab leaning against the cabinet.
Looks like the top is GRP.
In this case we hope far enough north-side to not cast a shadow.
From previous comments, on top is some kind of trig point.
