Lidar visualisation 2

Taking that last map of slope severity and draping it over a 3D surface model. Some things certainly more evident. I hadn't noticed the hollow way ascending the slope in the bottom left previously; earthworks below the woods in the bottom of the valley; still wonder what to make of the mounds on the far hillside. This produced using SAGA GIS which I'm more impressed with the more I get to grips with its capabilities.

Derwent Valley - Little Eaton

This is a Lidar plot of part of the Derwent Valley just north of the city of Derby at Little Eaton produced with Environment Agency data. I've just dug this out for a potential upcoming project. It was created for an external client some time back (to be honest I can't entirely recall for what purpose). Downstream is the site of the Roman fort at Littlechester, of which I probably do have an image somewhere. Here we see the river channels and levees of the Derwent and surviving areas of medieval ridge and furrow.
