Biography:
David Secretan-Hallett is a senior software engineer at CSIRO, specializing in the design and development of geospatial visualisation applications. His work focuses on building scalable and efficient solutions that support scientific research in the field of coastal modelling.
Abstract:
Responsive and interactive visualisation of large geospatial datasets has always been a challenge. With more and more models outputting their data in irregular or unstructured grid formats, some tools have started to fall behind.
One of the largest hurdles for tools, is large scale 4D model result datasets that use an unstructured grid. These datasets have file sizes exceeding 100GB with more than 1.4 million polygons, which presents major challenges when trying to load, manipulate and render the data for interactive visualisation.
With open-source libraries and industry standard tooling, I’ll show you how we achieve responsive interactivity with large scale models using just a laptop. No HPC nodes required!
