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 […]Read More More sea ice reconstructions
I recently attended to a workshop on AgTech innovation, hosted by the Canberra Innovation Network and the US Embassy. It was a fun and really useful day out – hearing stories about what drives the agriculture sector, what they see as innovative, and how niches in the sector are filled by innovators literally ‘on the […]Read More Open AgTech – a prelude
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. […]Read More The LiDAR uncertainty budget II: computing uncertainties
This is part 1 of 2, explaining how uncertainties in LiDAR point geolocation can be estimated for one type of scanning system. We know LiDAR observations of elevation/range are not exact (see this post), but a critical question of much interest to LiDAR users is ‘how exact are the measurements I have’? As an end-used […]Read More The LiDAR uncertainty budget I: georeferencing points
LiDAR is a pretty common tool for geospatial stuff. It means ‘Light Detection and Ranging’. For the most part involved shining a laser beam at something then measuring how long a reflection takes to come back. Since we approximate the speed of light, we can use the round trip time to estimate the distance between […]Read More LiDAR thoughts – where to measure, exactly?
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 […]Read More ACE CRC, Airborne LiDAR and Antarctic sea ice
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 […]Read More A short visual history of shipping access to Australian Antarctic stations
The cover photo for this site shows.. the back of my head, a Leica Viva TS 15, a prism, and a bright yellow, low cost, very effective instrument warming/battery box I’m very proud of! I’m acquiring prism lock using the remote control, before heading out to collect locations on a SIPEX II ice station. The sea […]Read More Acquiring prism lock: the cover photo
