#SundayWriting - waking up some old data in the process of writing a 'science rescue' story, aka the only place some ideas are ever likely to be published. This is from a voyage in 2012, partly written up in a doctoral thesis in 2016, for a project de-funded in 2013. It's 3 #lidar swaths, #photogrammetry and TLS data all aligned to tell stories.

...but wait - sea ice drifts, and... snow is white... and... over a decade ago? ...how?

yes.

#fedihire me to find out ;)
A screenshot showing lidar swaths over sea ice, coloured blue -> white by elevation, with RSV Aurora Australis near the centre, coloured orange and green. Just in front of the ship at ice level is a patch of high density points in 'real colour' from a photogrammetric survey (same aircraft), and floating above the patch in blue -> green is a terrestrial lidar scan of the same area.
