I’ve been taking different AUV datasets through Qimera and I must say, it is really easy. It is even easier now that as well as the post processed inertial SBET format, I have been beta testing the Kongsberg Navlab post processed position and pressure formats too. It only took a minute to get all the […]

Fantastic ESRI Story Map on the history of multibeam water column
This fantastic story map provides a history of the development of water column processing from research to reality. It was put together by Moe Doucet (@metamoe) from QPS and Victoria Price from Normandeau Associates. They presented it at @ESRIOceans this week. Well worth a view.

See the seafloor in new ways – Multispectral Backscatter
R2Sonic have just released a new firmware update that allows the system to ping in succession at different frequencies. It works best on the Sonic 2026 as this can ping at 100 kHz, 200 kHz and 400 kHz. QPS QINSy records the frequency with each ping and then FMGT (the backscatter app) processes each frequency […]

Grand Canyon combined multibeam and laser survey
Blowing my own trumpet here as I made the Fledermaus fly-through, but it is a great dataset that was collected by Seahorse Geomatics for the USGS using a Norbit iWMBS system and their new laser system. I processed the bathymetry and laser in Qimera and then did the visualisation trickery in Fledermaus.

Using “hydroacoustic properties” to date lava flows
Isobel Yeo of GEOMAR’s Helmholtz Institute for Ocean Research Kiel is calculating the date of lava flows from undersea volcanoes by using the reflectivity returned by sonar backscatter. Nice article on the BBC website here http://www.bbc.com/earth/story/20160808-the-volcanoes-hiding-in-the-ocean and her paper can be downloaded here http://www.sciencedirect.com/science/article/pii/S0012821X16000510

R2Sonic have released a major firmware update
It looks like R2Sonic have been busy. Pitch stabilisation and ROBO mode! Major firmware & GUI releaseStandard frequency range is expanded to 170-450kHz for Sonic 2026 systems, and Sonic 2022 and 2024 systems with model 1006 projectors.GUI now includes ROBO Mode for shallow water surveys less than 40m in depth, simplifying sonar operation.700kHz UHR option […]

MUNIN Pipeline Inspection
An excellent article here Read more… on the @KOGMaritime Kongsberg MUNIN’s pipeline inspection project in the Great Lakes. I used it to test out AUV processing in Qimera (following on from Loch Ness) and also the new pipeline inspection capability in Fledermaus. The image is showing the results in Fledermaus with the point cloud from […]

Qimera now available on OS X
Qimera (@QPSQimera) is now out to download from the QPS website. Looks great and runs faster than Windows (in my opinion anyway!). Download away https://confluence.qps.nl/display/dwn/Qimera

Qimera on OS X
Qimera is almost out on the Mac! I’m just testing out a pre-release build of Qimera 1.1. It was first released just on Windows but with 1.1 it will be on OS X and Linux. So for those of you with MBSystem, give QPS Qimera a go.

Surveying with ROVs? You need Time Series Multiplot
One of the main sources of error when conducting multibeam surveys from ROVs is the timing of the data producing artfacts in the bathymetry. Finding out what the latency is has not been easy. The way it used to be calcuated was to extract the roll data and an outer beam value and compare the […]
