Geodesea out in the Falklands!

THE PROBLEM: Remote MBES survey location (Falkland Islands), no local geodetic control or on site GNSS base station.

THE SOLUTION: Hi-res MBES with integrated Applanix Corporation POSMV OceanMaster provided a fast and easy setup for quality data acquisition. Data was post processed in POSPac MMS with PP-RTX, to provide a robust, centimetre level solution without the need for external reference data.

PicoMB-120Surf used for port survey in southeast UK

Geodesea Ltd were recently contracted by the Port of London Authority to use the Pico MB-120Surf mounted on a Hydrone to complete a post dredge survey on the Thames Estuary. 

The use of a USV was beneficial as smaller conventional (manned) survey craft were not appropriate due to COVID-19 social distancing regulations in place at the time, with the added bonus that the USV could also pass beneath the Ro-Ro jetty due to its small size. 

Many thanks to the Port of London Authority and CRO Ports for sharing the data.

UAV Survey at Purfleet on the River Thames

Geodesea Ltd have teamed up with Droneflight Ltd (www.droneflight.com) to acquire and process photogrammetric data in the inter-tidal section of the River Thames behind a busy Ro-Ro terminal. 

The use of UAVs in these environments to acquire bathymetric data is ideal, where navigating a MBES equipped survey vessel is neither safe or practical. 

Completed on behalf of the PLA, we hope to do more similar works very soon.

MBMax LOG File Generator

Just created an MBMax log file generator, as last time I checked the Hypack version only allowed to merge 2 existing log files and I have been creating them in TextPad for use in MBMax.

May or may not be of use - it is to us! Download HERE and change *.txt to *.exe

Requires .NET v4.0.0.0 or later

Can easily be embedded into Hypack shell too :-)

May 2016

Geodesea Ltd now using Beamworx AutoClean

Geodesea have recently purchased a Beamworx Autoclean licence for MBES and vessel based LiDAR data cleaning.

Simple and robust point cloud cleaning program for Bathymetric and LiDAR point data. In times where software becomes more and more complex we present a new cleaning tool that is focused on day to day cleaning on board of survey vessels or near site. Very easy to learn, easy to operate and to install program. Due to its flexible import and export it will fit in every workflow.
