Burrough Hill Lidar

Burrough Hill lidar slope severity plot
I was surprised to see EA data at 0.5m centres available for this seemingly random block of Leicestershire countryside until I noticed this. So presumably this derives from the survey commissioned by the University of Leicester, although point density may have been somewhat higher in the original surveys to judge by that nice de-vegetated bare-earth model. Pleasing results from this nonetheless.

The first image is a slope severity plot; the perspective view from the south-west is based on a sky-view factor plot.

Old Sarum

The Iron Age hillfort and later motte (and cathedral) at Old Sarum, just north of Salisbury, Wiltshire. Environment Agency 0.5m-centred data (this stuff is starting to get impressively detailed) expressed as a sky view factor map with colour ramp.
