Qimera beta testing in full swing!
Excitement mounts as Qimera enters its second phase of beta testing. The first week of December marked the kick-off of Qimera’s beta testing phase when several industry users met in QPS’ Portsmouth, NH, USA office to try their hand at the latest QPS software product. Users remarked that they were impressed by the ease of use and guided processing workflows.
Colleen Peters of Schmidt Ocean Institute stated, "I am very excited to use Qimera on board. We often have students and scientists on our ship that have never processed multibeam data, so having one package that can ‘do it all’ will significantly simplify our workflow from start to finish. Compared to other products I find it easy to learn and more importantly it will be easy to teach.”
And Ryan Larsen of C&C Technologies says, "I found Qimera's workflow to be quick and intuitive. Qimera is easy to learn while retaining advanced features for dealing with problem data sets. I think that our final products will look better than ever."
A parallel group in Europe participated in a similar round of demonstrations and testing. The second phase of beta testing will continue in Zeist, NL this month as we champion towards completion and release of Qimera.

Tackling global issues
The STELAR-2S2 Project (School of Geography and Environment)
STELAR-S2S is a multi-institutional project, led by the Geography and Environment Department at the University of Southampton. The project is developing new insights into the way large rivers interact with climate to modulate sediment transfer from the river's source to their sinks zones (e.g. in deltas). This requires detailed understanding of the role of bank erosion, floodplain sedimentation and climatic fluctuations on sediment delivery and storage.
During 2013 and 2014 the team have undertaken four periods of fieldwork, deploying multibeam echosounders and terrestrial laser scanning survey equipment in conjunction with flow measurement technology. Additionally, using an inertial motion unit and an RTK differential GPS in conjunction with the survey equipment yielded a series of ultra-high resolution point clouds of more than 300 kilometers of the submerged river bed, bank toe and material above waterline of the Mekong River in Cambodia. For more information about the Stelar project please check the official website: http://www.stelar-s2s.org/project/project_intro.html
QINSy was successfully used by the team from the University of Southampton to collect terrestrial laser scanning data, delivering on-the-fly geo-referenced point cloud co-ordinates in real-time corrected for motion, heading and timing. Final point clouds were immediately available after the last data recording session; as the team members put it: “Spectacular real time acquisition provided by QINSy makes the post processing superfluous.”

Ongoing work will characterise the nature and volume of change to the bed and bank on the Mekong, helping to parameterise models that will seek to predict changes in sediment transfers under scenarios of climate change.

QPS Client Spotlight: Groningen Seaports
Groningen Seaports is the port authority for Delfzijl, Eemshaven and the adjoining industrial sites. Groningen Seaports provides a complete package of port services to its clients from logistics and infrastructure services to the maintenance of sites.
The company has a long history managing the seaport of Delfzijl, which until 1819 was managed by the Dutch Government. Since 1819, it has been managed by the province and local governments and has been called Groningen Seaports since the year 2000.
Groningen Seaports currently has 80 employees. The Dredging & Surveying department is responsible for the safety of navigation and for the ports accessibility for cargo vessels, regular hydrographic surveys play a key role in the port's availability. With the regular surveys that Groningen Seaports are doing, they have an exact knowledge how the ports' bathymetry looks and where special attention is required in order to prevent siltation of the port. Their vessel "Havenschap 1" has a Kongsberg EM2040 multibeam system installed in a moonpool together with a Kongsberg EA400 singlebeam dual frequency echosounder. With the 210kHz and 33kHz channels of the singlebeam, Groningen Seaports gains even more knowledge about the fluid mud layer floating above the seabed in the port which is causing siltation of the port. Monitoring this fluid mud layer is a crucial part of the work that the Havenschap 1 and its crew is doing. Until 2012 their multi-tasking surveyor navigated the boat and collected hydrographic data simultaneously without loosing an eye on perfect data quality. For health and safety reasons it was decided in 2012 there should be two men on board.
With only one person doing the survey and steering the boat an efficient way of data collection, cleaning and charting was required. QPS products enabled this efficient workflow and continues to do so. Groningen Seaports has been a QPS client since 2000, when QINSy 7.5 was brought to the market.
Groningen Seaports find QINSy offers great tools for their surveyor and skipper to QC data during collection. Jakob, the surveyor who will retire by the end of 2018, says: " When we notice something is not right with the data, we can quickly erase the erratic data and then re-do the line. This way we don't lose time on processing and de-spiking the data. The QINSy online displays and QC tools are very powerful. "
Successful transition from Qloud to Qimera
" Also the workflow with Qimera for filtering and de-spiking the data works really good for us. Qimera is fast de-spiking the data. Recently we've moved from Qloud to Qimera. Since we are using Qimera, we've reduced the time de-spiking the data with 50%! We are happy QPS users". This efficient workflow enables them to deliver the data to the dredging company within one hour, following a four hour survey. They take the data from Qimera into Processing Manager and then using Processing Manager for calculating volumes and for creating the final depth charts.
If there are questions about software or technical problems, Groningen Seaports get in contact with QPS Support. Jakob says: "QPS offers excellent support; when we contact the Support department, we are always immediately being helped. This is also why we are choosing QPS".
