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.

The village of Lalung, located along the Spiti Valley of Himachal Pradesh in northern India, is the site of the historically significant Buddhist "Golden Temple". Together with the Institute of Architectural Theory, History of Art and Cultural Studies at TU Graz, the Engineering Geology group at TU Graz constructed 3D laser scan (LiDAR) models of the impressive gilded wooden carvings bedecking the walls of the Golden Temple of Lalung. This video is a fly-through of a true color point cloud of the main Serkhang. Field survey was performed with the Riegl LMS Z620 terrestrial laser scanner.

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.
Paul LaRocque, vice president of Advanced Technology for Optech Incorporated, talks about Bathymetric LiDAR for Hydrographic Mapping, with a focus on ALTM systems and data fusion. LiDAR systems have been adapted for marine, space, and terrestrial mapping. He discusses the world’s first commercial airborne laser terrain mapper - the ALTM. Created by Optech Inc., they include a shallow water, and a deep water mapper. Testing was done in Lake Ontario for the shallow water system, and it successfully mapped the land surface, water surface, and bottom. The deep water mapper is the coastal zone mapping and imaging LiDAR that provides nine layers of data about the water being evaluated, including information about coral, sand, and vegetation. Optek was also a key partner in getting LiDAR on M...
Meet David Sabatier, RTM (site engineer and deputy department head), Pyrénées-Atlantiques and the Hautes-Pyrénées counties. In order to understand the “sliding” phenomena affecting the Pyrénées mountains, MTSI worked with RTM to identify the structures on forest-covered slopes to detect the landslide and reconstruct the site’s geological history.
Recent advances in both airborne and terrestrial LiDAR (Light Detection and Ranging) technologies allow imaging of Lake Tahoe landforms in a completely different light. In 2010, the Tahoe Regional Planning Agency and partners funded the first airborne LiDAR survey of the Tahoe basin,providing an amazing data set to explore landforms. This technology allows the user to strip away trees (or study the canopy) to reveal an amazing picture of unheralded clarity (sub-meter horizontal and 3.5 centimeter vertical resolution). Active faults, landslides and other landforms jump off the screen, enabling discoveries such as the landward extension of basin-forming faults (such as the West Tahoe and Incline Village faults). Paleo-landslides abound. Together with Sonar mapping in the lakes of the Tahoe B...

Seeing Shape: An Introduction to LiDAR Mapping Technology Presenter: Ralph Haugerud, Geologist, USGS Affiliate Assistant Professor, Department of Earth and Space Sciences, UW College of the Environment The 4th Annual University of Washington GIS Day was held on Wednesday, November 19th, 2014, in the UW Libraries Research Commons. GIS Day highlights and celebrates the transformational role of Geographic Information Systems (GIS) and Remote Sensing Technologies. This session was one of two specialized talks on LiDAR mapping technology. For more information on LiDAR, visit http://oceanservice.noaa.gov/facts/lidar.html.

http://gallery.usgs.gov/videos/541 This video provides a visual example of how airborne LiDAR (Light D etection And Ranging) imagery penetrates dense forest cover to reveal an active fault line not detectable with conventional aerial photography. The video shows an aerial perspective of the range front Mt. Tallac fault, which is one of five active faults that traverse the base of the steep mountains west of Lake Tahoe, California. The USGS has recently published a report in the Bulletin of the Geological Society of America that details the seismic hazards of the Tahoe -Sierra frontal fault zone mapped with the new technology.
