Because we all focus so hard while writing workshops for FOSS4G SotM Oceania 2018, right? Here are a couple more ‘fun with sea ice’ visualisations. There’s nothing really scientific about these, they’re based on some proof of concept work which is very slowly iterating toward science. So, just enjoy! Firstly, SIPEX II Ice station 7…

Ice floe interactive visualisation, take 1
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….
The LiDAR uncertainty budget part III: data requirements
Part I of this series described the LiDAR georeferencing process (for one, 2D, single return scanner). Part II showed how point uncertainties are computed and why they are useful. What hasn’t been covered so far is what data you need to do this stuff! Here is your shopping list: Scanner data Raw LiDAR ranges Scanner…
The LiDAR uncertainty budget II: computing uncertainties
In part 1, we looked at one way that a LIDAR point is created. Just to recap, we have 14 parameters (for the 2D scanner used in this example) each with their own uncertainty. Now, we work out how to determine the geolocation uncertainty of our points. First, let’s talk about what those uncertainties are….
ACE CRC, Airborne LiDAR and Antarctic sea ice
Between late June and late August 2015 I worked with the Antarctic Climate and Ecosystems Co-operative Research Centre (ACE CRC) to tidy up some long running loose ends with an airborne LiDAR project. This project is close to home – my PhD revolves around cracking some of the larger nuts associated with getting a science…
A short visual history of shipping access to Australian Antarctic stations
In late 2014 I was contracted by the Antarctic Climate and Ecosystems Cooperative Research Centre to analyse Antarctic shipping patterns from 2000 to 2014. The aim was to extend a planning report first published in 2008, and provide deeper insights into shipping patterns in order to plan for future shipping seasons. Obvious shipping routes arise as…
