Web GIS Improves Lidar Collection Response Time

The remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality laser data, storing and managing the huge volume of Lidar data collected can prove to be a challenge. Combined with associated metadata such as survey information, environmental conditions and flight lines, data management has now become a critical priority and focus. An initiative called the Lidar Management and Analytical Processing (LMAP) provides an automated workflow for uploading and storing Lidar and metadata into a Geographic Information System (GIS). Developed... (read more)

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)

Australian Lidar Bathymetry Survey for Fugro

Fugro has been awarded the contract to conduct an Airborne Lidar Bathymetry (ALB) survey of the Queensland Sunshine Coast (Australia) to be conducted during October and November 2011. The main reason of the survey is to develop a high resolution digital elevation model and other derived products in order to help manage this environmentally and economically important coastal region. The contract has been awarded by Australia's Cooperative Research Centre for Spatial Information. It will provide data to stakeholder partners including Queensland Government's Department of Environment and Resources Management (DERM), Department of Climate Change and Energy Efficiency (DCCEE), Commonwealth Scientific and...

Optech Celebrates 40 Years of Lidar Innovation

Optech is celebrating 40 years of Lidar technology innovation. To mark the milestone, Optech is paying tribute to the incredible partnership with its clients over the years, from the first commercial Lidar systems in the world to solutions for bathymetry and UAVs. A celebratory event was held at Niagara Falls, including an exhibition of projects and the evolution of Optech Lidar technology that has supported clients over the last 40 years. Lasers were barely out of their infancy in the late 1960s, yet founder Dr Allan Carswell saw their potential for revolutionising remote sensing and began developing prototype Lidars at... (read more)

Coastal Zone and Bathymetric Lidar Conference Session

The first European Lidar Mapping Forum event is being held in The Hague, in the Netherlands from 30th November to 1st December 2010 and will have two conference sessions devoted to coastal zone and bathymetric Lidar. Novel approaches to laser-based hydrographic data acquisition and the evolution of coastal mapping and monitoring utilising Lidar and hyperspectral systems will be discussed along with the application of boat-mounted mobile Lidar.In addition to the conference there are 50 leading Lidar manufacturers and service providers exhibiting. This will be the largest ever European exhibition dedicated solely to Lidar technology and services.For those still looking to... (read more)

Multispectral Lidar Solution for Shallow-water Surveys

Leica Geosystems and Airborne Hydrography AB have presented Chiroptera II, a Lidar solution for topographic mapping and shallow-water surveying in depths of up to 15 metres. The system simultaneously captures the full waveform in both the 35kHz bathymetric channel and the 500kHz topographic channel to provide high-detail maps for environmental and coastal monitoring, infrastructure planning, and other near-shore applications. The latest version incorporates the Leica RCD30 80-megapixel medium-format camera, NovAtel SPAN GNSS-IMU subsystem, Leica MissionPro mission planning software and Leica FlightPro flight navigation software. It also features a new scanner package that allows installation in the Leica PAV100 stabilised mount,... (read more)

Lidar Bathymetry on the Alaskan North Slope

Inventory and Characterisation of More than 4,500 Shallow-water Bodies
In June 2014, the Bureau of Economic Geology, a research unit at the University of Texas at Austin, was contracted to conduct an airborne bathymetric Lidar survey on the Alaskan North Slope. The purpose of the project was to further determine, understand, and map the local landscape and thaw-lake attributes of an area west of the Dalton Highway and Sagavanirktok (Sag) River, approximately 30km southwest of Deadhorse, Alaska. Researchers from the Bureau had visited the area in 2012 and found bathymetric Light Detection and Ranging (Lidar) to be an effective tool for measuring the area’s lakes. The group returned in...

Finistère and Mediterranean Bathymetric Lidar Surveys

A contract to conduct an Airborne Lidar Bathymetry (ALB) survey of the Finistère and the Provence-Alpes-Côte d'Azur (PACA) regions of France between February and May 2012 has been assigned to Fugro. The surveys will be conducted with the Fugro LADS Mk 3 ALB system. Covering a total survey area of 2,200 square kilometres, both surveys have been included in one contract in order to optimise survey conditions in two very different environments.   The project is being conducted as part of the Litto3D programme and is important for the protection of the coast from erosion and potential loss of habitat,...

Lidar Allows Sandy River to be Mapped

In September 2012, Watershed Sciences, Inc. (WSI) and Dewberry collected airborne topobathymetric Lidar data for the Sandy River in Oregon, USA. These data are being used to map channel and floodplain morphology and to evaluate the effectiveness of RIEGL’s VQ-820-G hydrographic airborne scanner in a Pacific Northwest riverine environment. The shallow river system - including side-channel and off-channel areas that are notoriously difficult to measure using conventional techniques - was successfully mapped using Lidar. The Sandy River in northwestern Oregon is a shallow river running from Reid Glacier on Mount Hood for 56 miles to the Columbia River and flows... (read more)

Best Practices and Inspiring Bathymetric Lidar Projects

Bathymetric Lidar is a technique to capture geospatial data of coastlines and waterbodies. The method has the potential to facilitate the fast and efficient creation of hydrographic data, and more and more users are turning to it to support many new and different applications. At Hydro International, we have selected a series of articles on this technique, ranging from case studies that zoom in on some challenging projects using bathymetric Lidar in combination with other survey methodologies, to in-depth articles focusing on the latest trends and developments relating to this hydrographic surveying technology.
