LiDAR is a useful additional tool alongside HER, cartographic evidence and AP evidence. Excellent for palaeochannels. Good for subtle earthwork features which you might need optimum conditions to see in the field, if at all. Piles of building rubble dumped by farmers can make themselves into interesting cairns though! As ever, a tool to be used as part of a suite of techniques.
