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.
How has LiDAR technology been used to uncover secret archaeology hidden beneath woodlands in the South Downs National Park. Secrets of the High Woods project, supported by the Heritage Lottery Fund and led by the South Downs National Park Authority in partnership with Chichester District Council and English Heritage.
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.

"Lidar" is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. Although thought by some to be an acronym of Light Detection And Ranging, the term lidar was actually created as a portmanteau of "light" and "radar". Lidar is popularly used as a technology to make high-resolution maps, with applications in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics, airborne laser swath mapping , laser altimetry, and contour mapping. Lidar originated in the early 1960s, shortly after the invention of the laser, and combined laser-focused imaging with radar's ability to calculate distances by measuring the time for a signal to return. Its first applications c...
This is a simple example of how LiDar technology gives an precise map of the terrain.
