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.
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.

A sophisticated technique using lasers from an aircraft to map the terrain below has been helped by Higher Level Stewardship funding. Lidar (Light Detection And Ranging), is a technique that is able to peel back the vegetation in the computer to reveal previously unknown landforms below. It has both archaeological and environmental uses that improve our knowledge of the New Forest, taking the Forest's past history into the future.
This is a simple example of how LiDar technology gives an precise map of the terrain.

3D Gaia is the first app for Geological field trips in virtual reality for training in the Oil & Gas Industry. It uses high resolution 3D outcrop models from images acquired with drones or Lidar. It also integrates Google Earth. Imaged Reality LTD is a virtual reality startup for the Oil & Gas Industry.
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.
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...
"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...
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...
