Topograph
From TrigpointingUK
Three topographs are listed in T:UK. These are:
| T:UK | Station name | Order | Computed | Block |
|---|---|---|---|---|
| TP7637 | Douglas Park | 3 | 1958 | NS04 |
| TP7939 | Tor Hill | 2 | 1988 | ST57 |
| TP7314 | Toys Hill | 4 | 1953 | TQ53 |
The Tor Hill Topograph may be a replacement for the nearby trig pillar which was recorded as destoyed in 1987. The station also includes an 'Old trig' (likely to be a buried block).
Elsewhere, trig pillars have been adapted for use as a topograph. For example, Beacon Fell where a circular plate covers the top.
The pillar at Hindhead features a National Trust plaque and emblem. In addition the spider has been replaced by a topograph. The pillar originally included a collecting-box, as illustrated on page 182 of The History of the Retriangulation of Great Britain
In the case of Brown Clee Hill, the pillar was
demolished in 2006 and replaced by a topgraph.
