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)

Using RAMMS to Acquire Integrated Land and Sea Data in the Caribbean

Fugro has completed a data acquisition campaign over the Turks and Caicos Islands, marking the first commercial success of its Rapid Airborne Multibeam Mapping System (RAMMS). Working under contract to the United Kingdom Hydrographic Office (UKHO), the company acquired more than 7,400 square kilometres of integrated, high-resolution bathymetric, topographic and image data. The resulting deliverables will support updated nautical charts and coastal zone management activities in the region. Launched in August 2018, RAMMS is a airborne bathymetric mapping system that uses multibeam laser technology to deliver industry-leading depth penetration and point densities. The compact sensor is deployed from a small aircraft... (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 as we head into 2019. Airborne Lidar bathymetry (ALB) is no exception to recent innovations, especially with the growing recognition in the importance of high-resolution data to inform 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 detail and...

Hydrographic Surveying: Where Do We Stand

The Ever-increasing Accuracy of Mapping the Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those within the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared to... (read more)

The Advancing Technology of AUVs

A View of the Autonomous Underwater Vehicle Market
Since the last autonomous underwater vehicle (AUV) review in 2016, the market has continued to grow. The biggest market for AUV systems remains the military. The world’s most advanced Navies own and operate low-logistic AUV systems for mine countermeasures (MCM) in very shallow waters. These systems can operate in confined areas where MCM vessels cannot. The same systems can also be used in search and recovery operations, hydrography and salvage. This market used to be dominated by a handful of AUV providers. However, the number of manufacturers is increasing. Defence primes are also investing in these technologies through internal development... (read more)

Wärtsilä Unveils Targetless Laser Sensor for Offshore Wind Farms

Wärtsilä has launched SceneScan, a targetless laser sensor for offshore wind farms. SceneScan Monopole is among the first laser sensors developed for offshore wind farm applications where the need for installing fixed reflective targets is eliminated. This technology is designed to increase safety onboard service operation vessels (SOVs), since vessel positioning sensors that rely on targets fixed to the structure, are often unreliable because of poor placement, poor quality, and obscurement by workers on the platform. SceneScan has been designed and developed by Guidance Marine, which was acquired by Wärtsilä in 2017. SceneScan Monopole’s advanced software allows the measurement of... (read more)
