This was quite an interesting project. The trig points fixed to control the photographic cover mostly needed a 50 or 60 ft tower to see through to neighbouring points. Transporting and building the towers had some moments. The isolated aerial views here, as distinct from the regular mapping photography (B&W) were taken to aid interpretation.

This is only a small selection of my photos of this project. You can see many more if you preview the second half of my photobook at: - http://www.blurb.com/books/1240867-angles-and-distances
