Scanmar Appeal Thrown Out

The Supreme Court of Norway has denied Scanmar's appeal in their lawsuit against Marport. The litigation between Scanmar AS, Scantrawl AS and Henning Skjold-Larsen on one side ("Scanmar") and Marport Canada Inc, Marport Iceland Ehf and Pronav AS on the other side ("Marport") has finally come to an end. The Supreme Court of Norway concluded that the case contains neither principal matters of importance nor any other circumstances which required an appeal to be heard. Originally, the litigation started as a patent infringement case, in which Henning Skjold-Larsen, the founder and Chairman of Scanmar, claimed that Marport's catch control system... (read more)

AquaPix Synthetic Aperture Sonar System for DRDC

Kraken Sonar Systems, Canada, has successfully completed sea acceptance testing of an AquaPix Interferometric Synthetic Aperture Sonar (INSAS) system for Defence Research and Development Canada (DRDC). Kraken delivered a dual-sided AquaPix INSAS2 system complete with an embedded real-time INSAS signal processing engine and two DataPod removable data storage modules. The CAD500,000 system was integrated into DRDC's Arctic Explorer-class autonomous underwater vehicle (AUV). DRDC is the national leader in defence and security science and technology. As an agency of Canada’s Department of National Defence (DND), DRDC provides DND, the Canadian Armed Forces (CAF) and other government departments as well as the... (read more)

Hydrography is to many in our profession an unfamiliar word. When in my early days explaining what my job comprised I used to extrapolate it from ‘hydro’ and ‘graphy’, the last component meaning that we wrote down our measurements/findings. And I always added to this the important fact that we were able to retrieve them. Over the years, archives of survey records, echosounder recordings etc. have grown and grown. Each company or service had (and has) its own system of numbering fairsheets, wrecks and BT-observations and devised overview charts to make it ‘easy’ to trace or compile something. We had...

Naval National Protection Initiatives Support

The Mexican Navy is now using ERDAS APOLLO to manage and serve geospatial imagery and data in support of its national protection initiatives. The Mexican Navy imagery warehouse includes hundreds of terabytes and thousands of images. Imagery and derived products are acquired and produced daily. In early 2007, the Mexican Navy was struggling to keep its imagery catalog up-to-date. Additionally, it was under pressure to make sense of the increasing variety and quantity of imagery products being delivered and respond to growing internal and external demands for that data.     Since 1941, the Mexican Navy has carried out the...

GIS: Is the Hydrographic Industry Benefiting?

It is clear Geographical Information Systems (GIS) are providing added value business solutions in the wider geomatics world; this may be seen reading the many articles in the Geomatics Information Magazine, GIM International. So why is there such a slow uptake in many parts of the hydrographic world? GIS can also play a fundamental role in the integration of different types of hydrographic data. Data can be brought together better in one common interface and thus provide support to improve the data management and decision-making process all through the life-cycle of data. So why are many of the specifications for... (read more)

OceanAlpha Delivers Innovative USV Solution to Mining Industry

OceanAlpha’s autonomous bathymetric survey boat, the ME40 for hydrographic survey, has been applied in the mining industry for tailing dam surveys, in addition to its common application in lakes, rivers, reservoirs and oceans. All that is necessary is to set up the survey waypoints; the boat can then acquire online bathymetric data automatically based on GPS navigation. Water and tailing management is a key control process in mine management. Bathymetric surveys of tailing dams are important because the pond floor under the water is constantly changing and the water volume storage is therefore also changing. Local authorities may also require mining companies to... (read more)

3D at Depth Reaches Milestone in Offshore Lidar Metrologies

3D at Depth, a global provider of advanced subsea Lidar (SL) systems and survey support services, has completed its 300th subsea Lidar spool metrology. The subsea Lidar measurement, conducted offshore within the Mediterranean Sea, covered eight long spool metrologies with lengths greater than 90m and was completed in 24 hours. The project delivered considerable savings overall for the EPIC installation contractor and provided valuable 3D data for the oil and gas major (end user). 3D at Depth is the world’s leading expert in subsea Lidar technology and first introduced subsea Lidar metrologies for the offshore market 3.5 years ago in the...

Canadian Hydrographic Society

The Canadian Hydrographic Association (CHA) wrapped up another successful conference (CHC2014) in St. John’s Newfoundland and Labrador this past April. Partial proceedings are now available through the CHA website, www.hydrog­ Proceedings of the past several CHCs are also available through this site. Plans are underway for CHC2016 in Halifax Nova Scotia at the Westin Hotel from 16 to 19 May 2016 and CHC2018 in Victoria, British Columbia at the Empress Hotel from 5 to 8 March 2018. Lighthouse magazine, the journal of the CHA, is no more. With the publication of Edition 82, this brings to a close the more... (read more)

Integrating UAS and Multibeam Echosounder Data

Creating a 3D Landscape Model of a Gravel Quarry in Germany
Knowing the volume of material present in a gravel quarry can make the difference between profit and loss. A gravel quarry in Hartheim am Rhein, southwest Germany, is partially covered by artificial lakes. To determine the volumes of the above-water gravel dumping grounds and to map the bottoms of the lakes, high-precision data captured by an unmanned aerial system (UAS) was combined with multibeam echosounder data obtained by boat. Read the full article for a description of acquisition of the two types of data, how they were integrated and the benefits for the mining company. A gravel quarry is associated with diggers, rough...

Offshore 3D Laser Scanning

Versatility in many challenging applicatieons
Surveying is benefiting from continually evolving new technologies. One is 3D laser scanning, which is often used for measurements in complex industrial installations such as pipeline-rack crossings or entire petrochemical installations. Laser scanning is also increasingly being used in the field of prototyping and cultural heritage. In fact, it is safe to assume that this technology will be beneficial in any challenging environment, or for complex shapes. Laser scanners emit a narrow laser beam and then receive and process the signal returned by reflection from the object. Depending on the model selected, laser scanners can measure between 100 and 500,000... (read more)
