Post-processing Solutions at Northeast Lidar Workshop

Blue Marble Geographics' Director of Product Management, Sam Knight, gave presentations at NOAA’s Northeast Regional Ocean Council’s Northeast Lidar & Sea Level Rise Impacts Workshop on 10 and 11 July 2012 in Portland, USA. Knight focuses on post-processing of Lidar data with the Blue Marble Desktop and Global Mapper. The talk demonstrates the latest Lidar post-processing tools for coping with these challenges in the software. Both tools have powerful features for preparing data and analysing it, whether it be in transforming the elevations between geoid models, processing the high volumes of point cloud data into manageable chunks, or deriving terrain...

Imaging Lidar Environmental Monitoring Capabilities Highlighted

Teledyne Optech’s Coastal Zone Mapping and Imaging Lidar (CZMIL) system is a rapid environmental assessment tool for monitoring natural and man-made disasters. From detecting sewage pipe leaks, mapping oil slicks and measuring coastline changes after hurricanes, to counting underwater debris in the Great Pacific Garbage Patch, CZMIL is able to identifying and monitoring oceanic environmental changes, especially in emergency scenarios. Presentations are held during Oceans’17 MTS/IEE Aberdeen, UK and the Teledyne CARIS International User Group Conference in Ottawa, Canada. At the Oceans '17 MTS/IEEE conference in Aberdeen, Scotland, senior scientist Dr. Viktor Feygels will present ‘CZMIL as a Rapid Environmental... (read more)

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...

Mapping Underwater Terrain with Bathymetric Lidar

Two Similar Projects in Different Parts of the World
High-resolution bathymetric surveys support aquaculture research and increase navigational safety. In a case study, Tim Webster reports how this is done at Cape John Peninsula in Canada. In a second case study, Carol Lockhart describes a project in the Kingdom of Tonga, a Polynesian archipelago comprising 169 islands that stretches across approximately 800 kilometres in the South Pacific Ocean. Measuring water depth for nautical purposes dates back to ancient civilizations. As technology has evolved through the centuries, besides ship-based echo sounding, remote monitoring and mapping of water bodies has become increasingly available via Lidar bathymetric surveys conducted by airborne systems....

Lidar in Shallow Survey Data Comparison

In September 2011, New Zealand's LINZ hydrography team released a Request for Proposals (RFP) to collect Lidar (Light Detection and Ranging) bathymetry data for the Wellington Harbour and Abel Tasman areas.     The idea for LINZ contracting the collection of some bathymetric Lidar data came about for a number of reasons: to measure the performance of the latest Airborne Laser Bathymetry (ALB) systems; to collect data in Wellington Harbour as part of the Common Dataset for the Shallow Survey conference (SS2012) http://www.shallowsurvey2012.org/ in February 2012 and to see if gravity measurements could be combined with Lidar on one platform to save...

European Lidar Mapping Forum Presents Full Programme

The European LiDAR Mapping Forum (ELMF) 2014 conference programme has been posted online. The event will take place from 8-10 December 2014 at the Passenger Terminal Amsterdam (PTA) in Amsterdam, The Netherlands. There are two ‘blocks’ dedicated to topographic and bathymetric Lidar survey. The bathymetry presentations include on Tuesday 9 December 2014 INFOMAR as Ireland’s approach to Marine Mapping; a New Multi-wavelength Lidar System for 3D Land Classification and Coastal Bathymetry and on Wednesday 10 December Documentation of Flood-Induced Changes of Fluvial Topography Based on Airborne Laser Bathymetry, Airborne Coastal Surveys by the Korea Hydrographic and Oceanographic Administration and  The...

LAS Domain Profile Facilitates Topo-bathy Lidar

Thanks to a recent initiative of the ASPRS Lidar Division, different segments of the Lidar mapping community now have the ability to customise the LAS file format to meet their application-specific needs. The new mechanism that makes this possible is the LAS Domain Profile, which is a derivative of the base LAS v1.4 specification that adds (but does not remove or alter existing) point classes and attributes. It also supports topographic-bathymetric Lidar. The Topo-Bathy Lidar Domain Profile adds point classification values for bathymetric point (e.g., seafloor or riverbed; also known as submerged topography), water surface, derived water surface, submerged object,...

Leica Geosystems Enters Lidar Bathymetry Market

Leica Geosystems is strengthening its market position in airborne surveying through Hexagon’s acquisition of Airborne Hydrography AB (AHAB, Sweden), a provider of airborne laser survey systems for hydrographic and topographic surveys. Founded in 2002 and based in Jönköping, AHAB serves international survey companies and governmental organisations around the world, with hydrographic and topographic software and systems to map land, coastal zones and sea floors. Their product portfolio includes airborne bathymetric Lidar technology, which provides the equivalent of above-water topographic maps, enabling underwater objects to be detected and deep and shallow waters and coastal zones to be mapped and monitored. The... (read more)

Emerging Trends in Bathymetric Lidar Technology

What is on the Horizon for Airborne Lidar Bathymetry?
A surging interest in remote sensing and analytics has seen technology developments linked to these domains take off over the past couple of years. Airborne Lidar bathymetry (ALB) is no exception to recent innovations, especially with the growing recognition in the importance of high-resolution data to inform the management of our oceans, seabed and coastal zones. In our recent discussions with ALB manufacturers and experienced operators, several significant new developments were revealed. The new developments include: Lightweight ALB sensor alternatives driven by the proliferation of Unpiloted Aerial Vehicles (UAVs). Increased point density for ALB across all feasible depths for improved... (read more)
