Castleshaw Lidar

Many of the following Lidar images are large (up to 27MB), especially the 5km x 5km ones
and open in their own windows from where they can be downloaded/zoomed/saved.


3D Lidar Overview
3D Lidar Model of the 5km x 5km map below.

The Roman Road can be seen emerging from Austerlands (lower left, you will need to zoom in) and traversing the landscape to Castleshaw (Top right)

The quarry at High Moor is prominent in the centre, with Knott hill to its right directly above Delph village.
The Castleshaw valley runs from Delph towards the top right (and the Castleshaw reservoirs).

3D Lidar view along the Roman Road towards Delph (Hull Mill dam) from the Forts.
This is a 'telescope' view from the forts , the image is very foreshortened making Hull Mill dam appear much closer to the forts than it really is.
The visible Roman Road in the image is 1.1 miles in length.
