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.
Airborne LIDAR is an optical remote sensing tool that uses laser pulses to measure the precise distance to the ground. The airplane-mounted laser range-finding system, transmits and receives data, which are precisely located using a highly sensitive GPS receiver. Computer-generated images reveal hidden faults not seen through the vegetation. This example uses U.S. Geological Survey lidar images taken near Lake Tahoe and reveals a previously unknown fault cross cutting moraines.

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.
The partnership between Velodyne LiDAR and Phoenix LiDAR took to the skies in 2012 and has since transformed the aerial mapping and surveying industry. Together, the two companies launched the industry's first commercial UAV LiDAR system, establishing today’s broad use of LiDAR-enabled Unmanned Aerial Vehicles (UAVs).

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.

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...
