Honored to keynote GIS-IDEAS 2026 at Hanoi University of Mining and Geology, Vietnam on what should tokenize space for a Geospatial Foundation Model: pixel, voxel, or object graph? The conversations with fellow researchers were the real highlight. Thanks to the organizers.

We recreated the 2011 Tohoku #tsunami using WebGPU-accelerated SWE & open geospatial data. Validation showed promising accuracy, including tsunami arrival time at Fukushima. A browser-based platform for flood, tsunami, #landslide, and water-flow simulation will be released soon.

My team at @Gaia3D has simulated part of the #Nepal–Tibet flash #flood using #magoFluid. Initially I assumed water hit the border checkpoint from behind. This shows a massive flow passing alongside swept over it. Thoughts are with the victims.

Meet glTF-Inspect. Most web-based glTF viewers render. This one analyzes. It was built and open-sourced by the colleagues who developed our 3D Tiles engine, mago3D-Tiler. Give it a look. znkim.github.io/gltf-inspect… #gltf #threejs
