Dr. Steven Pawley describes the ways that LiDAR has helped some of the challenges previously encountered in data collection for the surficial geology mapping program. Much of the north has been mapped already, with more planned through 2015. LiDAR is able to provide a lot of detail that isn't always detected using other methods. Dr. Steven Pawley is Quaternary Geologist with the Alberta Geological Survey and the Alberta Energy Regulator.
Engineering geologist, Pete Hobbs, explains how the British Geological Survey landslides team use Terrestrial Light Detection and Ranging (LiDAR). LiDAR is a land-based laser scanner which, combined with a highly accurate differential GPS and camera, enables us to produce 3D computer models of landslides in coastal areas.
This tutorial walks you through the process of downloading free LiDAR data online using the USGS Earth Explorer.

A sophisticated technique using lasers from an aircraft to map the terrain below has been helped by Higher Level Stewardship funding. Lidar (Light Detection And Ranging), is a technique that is able to peel back the vegetation in the computer to reveal previously unknown landforms below. It has both archaeological and environmental uses that improve our knowledge of the New Forest, taking the Forest's past history into the future.
