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.

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.”
