GeoTexture for Backscatter Data Processing Evaluation at AWI

Regarding co-registered, georeferenced backscatter data, the German Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) has recently been evaluating the Kongsberg Geoacoustics GeoTexture software suite for backscatter data processing, mosaic creation and seabed classification. The software performance has been optimised for the analysis of GeoSwath Plus backscatter data, as it allows for beam pattern correction, vessel motion and sea-bottom topography, which substantially improve the quality of the mosaics and simplify image analysis and interpretation. Back in 2012, AWI began assessing the pace of coastal erosion and the nature of sediment and organic matter transfer in nearshore areas... (read more)

HIPS and SIPS 11.0 Simplifies Bathymetric Processing Workflow

Teledyne CARIS has released HIPS and SIPS 11.0, the latest hydrographic data processing solution. This release introduces several improvements making it easier for users to start new projects and process data, as well as an enhanced user experience while interacting with survey data. For users looking for the simplest way to open and process their data, HIPS and SIPS now supports Drag and Drop for raw sensor files. When users Drag and Drop files onto the application, the raw data is automatically processed and georeferenced, and a gridded surface is created. Georeference Bathymetry Version 11.0 also offers one-step processing. The... (read more)

CenterPoint RTX Post-processing Service Adds Galileo and BeiDou MEO Satellite Preview

Trimble, USA, released a preview version of its CenterPoint RTX post-processing service at ION GNSS 2013, enabling GNSS observations using available Galileo and BeiDou Middle Earth Orbit (MEO) satellites. Powered by Trimble RTX technology, the free CenterPoint RTX post-processing service provides better than centimetre-level positions. The existing CenterPoint RTX post-processing site uses data from the GPS, GLONASS, and QZSS satellite systems. Through a link accessible from the post-processing website, users can enter a preview site and derive positions that also use data from available open service Galileo and BeiDou MEO satellites. With the addition of Galileo and BeiDou MEO support,... (read more)

Triton Elics International Announces Processing Suite for Benthos C3D

Triton Elics International yesterday launched C3Dsuite, a software package for collecting and processing sidescan and bathymetry data from the Benthos C3D Sonar Imaging System. The sonar can simultaneously collect co-registered bathymetry and side scan sonar with a single system. The C3D suite has acquisition and processing capabilities tuned especially for the C3D. The package includes enhanced Isis software which can handle the two data types. A window is used to display a 3D view of the side scan data draped with the bathymetry, this is updated in real time s the data is acquired. The C3D package also includes TEI’s... (read more)

Ship-induced Riverbank and Harbour Damage

Evidence for Claims Processing
The use of rivers and channels for various purposes entails many conflicting interests. Ships produce not only waves but also a deep fall in water level during their passing. This article presents detailed discussion of these issues and a method of preservation of evidence for handling claims for damages so caused. The constant extension of large ports means increasingly intensive use of existing infrastructure and available times for loading and unloading. The cruising speeds of ships are also on the increase thanks to propulsion techniques and pressure to maintain tight sailing schedules. Merchant shipping is concentrated more than ever on...

Multi-beam Error Management

New data processing trends in hydrography
The hydrographic community has tumbled headlong into a data boom. Hundreds of single-beam soundings are now replaced by millions of high-resolution multi-beam swath soundings. This boom is not free from the problems inherent in how data is to be handled by ever-shrinking staff and ever-increasing demands for ways to store, process and archive gargantuan datasets. Luckily, modern computer hardware and processors can handle the load. However, there is still the issue of affording resources for traditional data processing, where each sounding is scrutinised. What new software approaches are being developed to automate processing? This article describes one new and innovative... (read more)

Hydrographic Surveying in Dense Aquatic Vegetation

Digital signal processing for improved bottom tracking
It can be difficult to detect the true bottom depth beneath dense Submersed Aquatic Vegetation (SAV) using current hydrographic echo sounder systems. High acoustic reflectivity of the vegetation can result in depth declarations within the vegetation canopy. This leads to underestimating bottom depth and overestimating dredging quantities required. This is demonstrated at a harbour, densely colonised with a robust bladed seagrass. Two echo sounder systems were used simultaneously - one a widely used single-beam hydrographic echo sounder; and the other a similar system designed to detect SAV. Dramatically different results are attributed to differing signal processing approaches. This is further... (read more)
