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 […]

Using an R2Sonic sonar and wanting to process backscatter?
If you are wanting to collect great backscatter data to create mosaics then this poster from Jonathan Beaudoin is a must read. It shows you how to set the sonar up, use SVP data and then process it in FMGT. Download the poster and stick it on your wall here http://www.qps.nl/download/attachments/14352930/beaudoin_r2sonic_poster.pdf?version=1&modificationDate=1400116368523

ESRI’s Chart Server – super cool!
Here is the link to the NOAA ENC server powered by ESRI’s Chart Server. You can see the ENCs normally or you can use them with the ESRI Basemaps like the Image one in the second picture. The ENC can be fully inspected too. A bit more info; The NOAA ENC Online viewer is […]

Nice use of 3 different types of underwater mapping
Pearl Habour wrecks surveyed with multibeam, LiDAR and underwater photogrammetry. Coolest thing is making models of wreck artefacts by using 3D printers. The small USV is also pretty impressive – complete with R2Sonic 2020.
