I recently finished a proof-of-concept project with FrontierSI for creating some building blocks aimed at scaleable, programmatic quality assurance for hydrographic surveys. It was a fantastic opportunity to work on the foundations of some huge future projects on large scale hydrographic data collection. I set out thinking ‘great, I can PDAL all the things!’ –…

Making the MH370 map
I had a lot of fun making the feature image for my second open source point cloud infrastructure post – and I liked the map, so I thought I’d share the recipe. Unfortunately, it took a while because I decided to make it better! I hope I succeeded – I certainly had more fun and…
An open source point cloud infrastructure part 2: oceans
If you haven’t read part 1 of this miniseries, go take a look. To really briefly summarise, it tells a short backstory about why the PDAL + Entwine needs to be on the radar for anyone considering massive point-cloud based data management; and provides a couple of terrestrial examples. Here, we tackle hydrography. The GEBCO…
Browsing MH370
Last week Geoscience Australia released a vast bathymetric survey dataset from phase one of an intensive search for the missing aircraft, flight MH370. Read the full story here. I’ve been ruminating on the idea of treating bathymetric datasets in the same way I handle LiDAR surveys – as massive point clouds. So this dataset presented…
