CHS Contracts for Airborne Lidar Bathymetry

Fugro GeoSurveys, Canada, has been awarded a ‘Supply Arrangement’ by the Canadian Hydrographic Service (CHS) to provide Airborne Lidar Bathymetry (ALB) survey services. CHS will predominantly use this contract to procure ALB surveys, as needed anywhere in Canada, to support its nautical charting programme, particularly in shallow water areas which are difficult to access safely using vessel-based systems. ALB data also can be used for a variety of environmental applications in coastal and shallow water areas. Fugro’s ALB systems will be used to acquire hydrographic survey data and seabed imagery in shallow coastal waters, where it is far more efficient... (read more)

Airborne Lidar Bathymetry Survey in Eastern Canada

Fugro has been awarded a new task order by the Canadian Hydrographic Service (CHS) to conduct an Airborne Lidar Bathymetry (ALB) survey in Eastern Canada. The task order, which has been issued under a three-year contract that Fugro holds with the CHS, is in support of their nautical charting programme and involves the survey of multiple sites along the coast of Nova Scotia. This marks the second consecutive year that Fugro’s ALB system has been utilised by CHS to survey the shores of Eastern Canada.    Fugro’s ALB system, SHOALS-1000T, will be used to acquire hydrographic survey data and seabed...

Airborne Lidar Bathymetry Surveys in Canada

Fugro has been awarded task orders by the Canadian Hydrographic Service (CHS) to conduct airborne Lidar bathymetry (ALB) surveys in Eastern and Central Canada. The task orders, which have been issued under a supply arrangement Fugro holds with the CHS, are in support of their nautical charting programmes and involve the survey of multiple sites along the coasts of Quebec, Newfoundland and Labrador, Prince Edward Island, Nova Scotia and Central Canada. Fugro’s ALB systems will be used to acquire hydrographic survey data and seabed imagery in shallow coastal waters, where the acquisition of similar information by traditional vessel-based acoustic methods...

Insights into Multi-spectral Airborne Lidar

Mr Judah Westby, regional sales manager at Teledyne Optech, will deliver a presentation on the multi-spectral Optech Titan during the Asian Conference on Remote Sensing (ACRS) taking place from 19-23 October 2015 in Quezon City, the Philippines. The presentation, titled ‘New, Flexible Applications with the Multi-spectral Titan Airborne Lidar’, will explore new shallow-water survey data that the Titan provides and what can be done with it. The Titan’s data is showing how its 532nm channel penetrates up to 15 metres deep in clear coastal areas. By using all three channels, Titan can also measure up to 900,000 points per second...

Suitability of Airborne Lidar Bathymetry for The Netherlands

Netherlands authorities (Rijkswaterstaat and the Hydrographic Office of the Royal Netherlands Navy) are considering alternatives to singlebeam echosounding and MBES in the shallow water areas of their responsibilities. Airborne Lidar Bathymetry (ALB) is such an alternative system: it measures bathymetry by laser ranging with a pulse frequency of 1000 Hz from an airborne platform. ALB relies on the penetration of the light waves through water to measure distance. The propagation of light in water is hindered by the absorption of light by the elements in the water. Light is attenuated at increasing depth because of diffraction and absorption. The maximum... (read more)

French Gulf of Lion Airborne Lidar Bathymetry Survey for Fugro

Fugro has been awarded the contract to conduct an Airborne Lidar Bathymetry (ALB) survey of the Gulf of Lion (France) to be conducted during September 2011. The primary purpose of the survey, which will be conducted to IHO Order 1b standards, is to map the sand reserves from the back of the beach to the 10 metre isobath to create a seamless, regular and digital altimetric model of the sea and the adjoining portion of land. The contract has been awarded by Direction régionale de l'Environnement, de l'Aménagement et du Logement (DREAL) with technical evaluation of the project by the... (read more)

New Airborne Lidar Markets for Optech Titan at ELMF 2014

Optech is introducing the Optech Titan multispectral lidar sensor to the survey and mapping industries at the European Lidar Mapping Forum in Amsterdam, to be held from 8-10 December 2014. Experience the beginning of a new era in active sensing that will dramatically expand what is possible with Lidar. Dr. Paul LaRocque, Optech’s VP of Advanced Technology, will present the first results as a co-author in the paper ‘A New Multi-Wavelength Lidar for 3D Land Classification & Coastal Bathymetry’. Attendees will learn how users of a multispectral lidar like Titan can automatically and accurately classify target materials by comparing the... (read more)

Airborne Oil Spill Detection

OPTIMARE was selected for a contract to provide the latest version of its Maritime Surveillance System MEDUSA for the German Navy. The mission equipment will be installed into a brand new Dornier 228NG which will substitute one of the German maritime surveillance aircraft of type Dornier 228. The ordered MEDUSA suite includes OPTIMARE's oil spill sensors of type SLAR, IR/UV Line Scanner and VIS Line Scanner. Moreover, the MEDUSA system fully integrates the EO/IR, the AIS and the SATCOM system which will also be part of the mission aircraft. OPTIMARE is specialising in mission system and sensor technology for airborne... (read more)

Hydrographic Airborne Laser Scanner

RIEGL introduced the VQ-820-G Hydrographic Airborne Laser Scanner in September 2011. This device has been specially designed for combined land and hydrographic airborne surveying. The high-accuracy ranging is based on echo digitisation and online waveform processing with multiple target capability.   Laser range measurements for high-resolution surveying of underwater topography, the bottom of shallow waters and riverbeds, are carried out with a narrow, visible green laser beam at 532nm, emitted from a powerful laser source. Depending on water turbidity, this laser wavelength allows measuring into water.   (read more)

Airborne Hydrography Releases HawkEye III

The HawkEye III airborne topographic and bathymetric Lidar scanner has been developed for territorial water and nautical charting surveys according to IHO S-44. The multi-sensor Lidar system includes a 10kHz bathymetric channel for high accuracy and high data density for deepwater; a 35kHz bathymetric channel is optimised for shallow water and the transition zone towards the shore. A 400kHz topographic channel provides resolution in data for demanding topographic jobs. The HawkEye III captures the full waveform in all channels, deep bathy, shallow bathy and topographic. Optionally the system can also be combined with up to 80 MPIX RGB + Infrared... (read more)
