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.
Infrastructure monitoring is typically accomplished with regular inspections of bridges, levees, dams, pipelines, and other large-scale structures. This video reviews methods to perform 4-D (3-D + time) monitoring of infrastructure and reviews methods to achieve optimized accuracy.
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.
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.

"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...
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.
El Santuario Histórico de Machupicchu fue declarado por la UNESCO como Sitio de Patrimonio Mundial Natural y Cultural de la Humanidad a solicitud del Gobierno Peruano, inscribiéndolo como tal, el 09 de diciembre de 1983, Machupicchu comprende aproximadamente 37 mil hectáreas y está ubicado en una zona de interacción entre el dominio andino y el amazónico, resguardado por las cadenas de nevados del Salkantay por el sur y la Verónica por el norte. El Ministerio de Cultura a través de la Dirección Desconcentrada de Cultura de Cusco, está poniendo en marcha un ambicioso proyecto colaborativo que revelará a través del uso de tecnología de última generación, posibles vestigios en el área de 5 mil hectáreas del Santuario Histórico de Machupicchu. Propiciando de esta manera la investigación cien...
