Underwater Lidar System

The INSCAN underwater laser imaging system has been presented by CDL, UK, and 3D at Depth, USA. The system provides fast, high-resolution 3D data capture for surveying, as-builts and monitoring, and will be showcased at the Subsea Tieback conference which is being held at the Henry B. Gonzalez Convention Center in San Antonio, TX, USA, from 5 to 7 March 2013. INSCAN is a subsea Lidar system that uses proprietary technology developed by 3D at Depth and engineered by CDL for use in subsea environments up to 3,000m in depth. The system collects up to 40,000 points per second, provides... (read more)

NOAA Awards Lidar Contract

Fugro LADS has been selected by the National Oceanic and Atmospheric Administration (NOAA), USA, to provide Light Detection and Ranging (Lidar) hydrographic survey services to support nautical charting and related products anywhere in the United States. The contract is awarded for a three-year period, and has a maximum value of USD30 million. The first task order under the new contract has been awarded to Fugro LADS, and is to start in November 2010. The contract involves acquiring bathymetric and near-shore topographic Lidar data, water level information and other ancillary data that will be delivered to NOAA for application to nautical...

Exciting Applications for Lidar

Hydro International Interviews Dr. Johannes Riegl
The RIEGL laser scanner company has been innovating laser scanning technology for more than 30 years. The equipment can be found in the most remote and even challenging locations across the world and even in space. Dr. Riegl gives a behind the scenes view of RIEGL and explains how the differenent laser scanning technologies have evolved over the years. UAV will be seen in bathymetric applications more frequently in the future with laser scanning as well as cameras. The emerging markets also play a key role for RIEGL laser company and Dr. Riegl expects this to continue into the future.... (read more)

LiDAR Monitoring Coastal Erosion

A new bathymetric survey of the Corsican coastline has been commissioned to provide detailed information about ongoing coastal erosion on the Mediterranean island as well as to assess the impact of manmade structures both on future erosion and navigation safety. BRGM in partnership with OEC (Office de l'Environnement de la Corse) and with the contribution of AERMC (Agence de l'Eau Rhône Méditerranée Corse) have appointed BLOM, UK, and its Hawk Eye II scanning device, to undertake an aerial LiDAR survey of the Oriental Coastal Plain of Corsica, providing some 120km² of new data.   Subject to intense meteorological events, including...

Seawatch Wind Lidar Buoy

Fugro has chosen Global Offshore Wind 2012, held on 13 and 14 June 2012, for the launch of the group’s new Seawatch Wind Lidar Buoy, representing the next generation of multi-purpose buoys tailored for the renewable energy industry. It accurately measures the speed and direction of wind across the diameter of wind turbine rotors in profile up to 300m heights, whilst additional oceanographic sensors measure ocean waves and current profiles. The new buoy is the result of a joint industry R&D project utilising offshore and wind technology expertise from Norwegian universities, research institutes, the energy company Statoil and Fugro OCEANOR....

Lidar Seafloor Classification

New Application for HawkEye II Airborne Lidar System
Airborne Lidar (Light Detecting and Ranging) is a well-established remote sensing technique which scans the terrain and seafloor with high-frequency laser pulses. Until now, bathymetric Lidar data has been processed to generate marine depth information and seafloor topography. However, Airborne Hydrography AB (AHAB) has developed a new method of processing data which allows information about the actual properties of the seafloor to be extracted. The accuracy and efficiency of reflectance imaging for seafloor classification is demonstrated here with data from coastal sites in both Massachusetts and Sweden. By Xin Liu, Andreas Axelsson and H. Michael Tulldahl, Sweden. With its advantage... (read more)

Portable Underwater Lidar System

Canadian research institute INO has developed a submarine Lidar to measure the reflectance of the seafloor and water column. The system is used to determine the reflectance of the sea bottom so that the composition can be correlated with relative intensity data from aerial surveys. INO’s Lidar system helps to calibrate the results of airborne bathymetric surveys, increasing their accuracy and enhancing understanding of the results. INO is working closely with INRS-ETE to test the maximum depth achievable and calibrate the system in the water. This Lidar prototype has the potential to cover a range of 3 to 50m underwater....

Merrick & Company Awarded LIDAR Contract

Merrick & Company was awarded a US$345,000 contract to deliver raw and processed LIDAR data, 2-foot contours, and a DEM for 1650 square miles of Stearns County, Minnesota and a small portion of two neighboring counties, Sherburne and Benton. The project is funded by Stearns County, seven local municipalities, a watershed district, and a soil and water conservation district. The new LIDAR and derived data will be used throughout the county by various public and private entities for flood insurance analysis, planning and zoning studies for new subdivisions, watershed management, assessing land value based on production potential in agricultural zones,...

Award for Hydrographic Lidar Scanner

On 15 May 2013, RIEGL won the Geospatial World Award in the category Geospatial Technology Innovation Surveying at the Geospatial World Forum Conference in Rotterdam, The Netherlands, for the RIEGL VQ-820-G. According to RIEGL, the device is the first ‘tightly coupled’, shallow water, land and smart echo waveform Lidar sensor. The topo-hydrographic scanner demonstrated its ability during several live demonstrations over the course of the last few months. An example of these demonstrations is the data collection in Oregon/ USA of the Sandy River. The nature of the river makes it challenging for traditional transect or boat-based hydrographic surveys; thus,... (read more)
