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.
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.

Geiger-mode LiDAR technology offers the most accurate elevation data available. The sensor allows for collections on a larger scale than has been possible up until now, while also collecting data up to 10 times faster and at 10 times the resolution as top-of-the-line, existing linear LiDAR sensors.

The popularity of LiDAR is on the rise. This remote sensing method allows scientists and mapping professionals to examine natural and manmade environments with accuracy, precision and flexibility. The latest release of Surfer includes many new features that make it easy to process and visualize LiDAR data. This free webinar will show you how to import, combine, filter, manipulate, visualize, and export LAS/LAZ data. You will also experience the power of Surfer's new 3D viewer when you visualize the LAS/LAZ data as a 3D point cloud layer. View the data from all angles as you fly through, record, and take snapshots of the point cloud from any perspective.

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.

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...
