Multi-beam Data Processing

Using CUBE Surfaces for Nautical Cartography and Dredged Measurements
The evolution of acoustic sounders imposed on Hydrographic Service’s new methodologies for the interpretation, handling and application of hydrographic information. Considering spatial resolution and high-density data acquired by multi-beam echo sounders (MBES), algorithms such as Combined Uncertainty Bathymetry Estimator (CUBE) are used in the processing workflow to generate depths and uncertainty estimates. Can bathymetric surfaces be considered the final survey product in exchange of the traditional shoals selection? IHPT conducted hydrographic surveys in order to evaluate CUBE processing for nautical cartography and for dredged volume calculation. Shoals validated by hydrographer were compared with CUBE estimated depths and produced a new... (read more)

Preparation, performance and processing

Aqua Vision BV
With a background in oceanography, physical geography and electronic engineering, Aqua Vision BV, a small company with its headquarters in Utrecht (the Netherlands), is an all-round player in the fields of hydrography and oceanography. Since its foundation in 1995, the company has grown to become an internationally operating company with customers throughout the world. Among its customers are governmental agencies, research institutes and harbour authorities. Aqua Vision was founded in 1995 by Peter Meijer and Sicco Kamminga to focus on current measurements using acoustic Doppler current profilers (ADCPs). In 1996, it became a limited liability company managed and owned by... (read more)

Magellan BLADE GNSS Signal Processing

Magellan has announced its exclusive BLADE (Base Line Accurate Determination Engine) technology, a GNSS processing solution that facilitates centimeter-level accuracy for real-time and post-processing surveys and mapping operations. Magellan’s BLADE combines ranging and carrier phase data from two satellite systems, GPS and SBAS, for superior satellite coverage and signal reliability to enable rapid, centimeter-level solutions. Magellan’s BLADE is the first GNSS processing system that uses SBAS ranging and carrier phase measurements in the RTK data processing. These SBAS measurements, which are GPS-like, improve satellite geometry to allow centimeter-level accuracies to be achieved in a shorter time compared to GPS-only algorithms.... (read more)

New Post-Processing MobileMapper 6

Magellan has introduced a post-processing option and new feature to its low cost handheld GIS/GPS receiver - MobileMapper 6. The raw data collection capability enabling post-processing, is included as an option in the new version of the Mobile Mapping field software for MobileMapper 6. Current users of MobileMapper 6 can order the post-processing option (activation code) and upgrade their units, via a simple and free firmware upgrade. The new Mobile Mapping application also complement the MobileMapper 6 offer with value features such as 3D shape files support, e-compass input for direction measurements,  voice tags as attribute, image geo-referencing in the...

Survey Engine Processing Licences Investment

Osiris Projects has purchased ten new Survey Engine software processing licenses from Coda Octopus. This investment in the Survey Engine family of geophysical processing software includes nine purchases of the new Mosaic+ professional side-scan mosaicking package which is being launched at OI14. This investment takes Osiris Projects to twenty processing licenses and, combined with a fleet of five CodaOctopus DA4G sonar data acquisition systems and a further five digital acquisition software licenses, provides an extremely capable geophysical survey provision. Robert White, Principal Geophysicist at Osiris Projects, said the company has been working with Coda Octopus for over 10 years and... (read more)

High-resolution Side-scan Processing

Chesapeake Technology has presented a high-resolution capability for SonarWiz 5 that doubles the resolution of the earlier version. The result for side-scan sonar data is crisper, sharper mosaics, waterfalls and sonar contact images. Christian Mueller, Humminbird’s SAR side-scan operator, said that on a recent search he was able to narrow down almost 70 targets in the survey area to just five, with the first one being a hit.     Surveyors in all types of industries can use high resolution to resolve smaller features and see finer detail to improve productivity, security and safety. For example, Navy Route Surveys can... (read more)

Survey Processing Software for Italy

The Italian Hydrographic Institute (IIM) has selected CARIS HIPS and SIPS software for its hydrographic survey processing. IIM will now have access to the latest technologies as they become available. Among these will be the implementation in HIPS of a new framework from CARIS designed to handle very large volumes of multi-dimensional data called CSAR.   Likewise, IIM will have access to integration of Geocoder in HIPS and SIPS for processing multi-beam backscatter, which will enable users to produce better quality mosaics than ever before.   The Institute has been the official nautical charting agency of the Italian Navy since...

QuickStitch Processing Software Powered by EIVA

The dedicated QuickStitch software package has been designed specifically for data collected with a Teledyne BlueView 3D Scanning Sonar to streamline the review, cleaning and alignment process. Developed by EIVA from the NaviModel solution, which is part of the NaviSuite software suite, QuickStitch is based on industry-proven hydrographic software. Teledyne BlueView’s underwater 3D acoustic imaging equipment is used to inspect, monitor, measure and quantify areas of interest below the surface. The 3D Scanning Sonar scan from a fixed location and produce a highly detailed point cloud centred on the scan location. To obtain data over larger areas, multiple, overlapping point... (read more)

Advanced Wave Processing for Port-Log

OceanWise has recently added an advanced wave processing algorithm to its online environmental data sharing and publishing system, Port-Log. The algorithm has been developed by a market leading provider of waves processing software to the oil and gas industry. According to OceanWise’s MD, Dr Mike Osborne, this new capability allows users to browse and view wave parameters, such as directional spectra, and partitioned time series, in real-time or historically, alongside other environmental datasets contained within the Port-Log system. Port-Log is already processing real time data streams from a range of industry standard instruments, including directional wave buoys, downward looking radars,... (read more)
