I recently spoke at POLAR2018 about using aerial photography for observing the properties of snow on sea ice. I’d really hoped to present some new work I’d been trying out on estimating local curvature, roughness and other properties from high resolution 3D models of sea ice topography.
Unfortunately I didn’t get all the way there. Firstly, I reprocessed a bunch of data and the results were worse than work I’d done in the past. So back to the drawing board, and the fallback position of explaining a bunch of work we’ve done over the past decade. A PDF of my slides is available via researchgate, but preferentially wait for the interactive web version to finish – it’ll be more up to date, have better links and side notes!
I did, however, put together the beginning of a 3D visualisation for sea ice from the surface (using photogrammetric reconstruction) and below (from upward looking sonar). Click and drag below to move/zoom around; and expand the hamburger menu at top left to expose more navigation tools, measuring tools and styling options. Or, click here to open a full page view.
Many thanks to the Antarctic Climate and Ecosystems Cooperative Research Centre for funding the work behind this; and for getting me to Davos.
