Artificially Modified Ground An area where the pre-existing (natural) land surface or geological succession is modified by anthropogenic processes of material removal or deposition and may include Made Ground, Worked Ground, Disturbed Ground, Landscaped Ground and Infilled Ground.
Borehole any hole drilled or dug into the sub-surface for the purpose of extracting or investigating the material at that particular point. Commonly cylindrical the length of the hole will always be several orders of magnitude greater than its width or diameter.

LiDAR Light Detection and Ranging is a technique that measures distance by illuminating a target with a laser is reflected back to measure surface elevations to create a Digital Surface Model from which a Digital Terrain Model is derived.
Start Height The elevation at which the drilling and logging of a borehole has started. The elevation can be relative to a local datum or temporary benchmark or a national datum.
