I gave this talk at the Cesium Developer Conference 2025 in philadelphia. In this talk, I've shared my company's experiences of visualizing spatio-temporal data (e.g., chemical dispersion, atmospheric data, wind patterns, and water flow) using CesiumJS. While CesiumJS excels at rendering massive, heterogeneous 3D objects, visualizing spatio-temporal data remains challenging due to its dynamic nature. To address these challenges, we explored workaround solutions to efficiently handle and visualize large-scale spatio-temporal data, aiming for intuitive representation and realistic simulation. As a result, we successfully developed techniques for chemical dispersion visualization, water flow simulation, and atmospheric data rendering over time. - Download as a PDF or view online for free

#mago3DTiler Ver 1.13.0 has been released! mago3DTiler, an open-source converter for OGC 3D Tiles, now officially supports:
- OGC 3D Tiles 1.1 specification
- ECEF (Earth-Centered, Earth-Fixed) coordinate tiling
- And more improvements and fixes

Gaia3D built a real-time 3D flood simulation in the browser using #CesiumJS and Shallow Water Equation. It visualizes dam break & heavy rain scenarios. Results closely matched real flood zones. We plan to continue deeper research. #DigitalTwin #FloodSim
Honored to speak at Inter Regional Dialogue 2025 in Kobe, co-hosted by TCS & UNDRR.
I shared Gaia3D’s digital twin-based disaster management cases & highlighted the value of #OpenStandards, #OpenSource, and #OpenData for building resilience. Thank you for the kind invitation!
I gave this talk at the Inter-Regional Dialogue 2025, co-hosted by TCS (Trilateral Cooperation Secretariat) and UNDRR (United Nations Office for Disaster Risk Reduction). In my presentation, I shared several digital twin-based disaster management cases conducted by my company, Gaia3D. I especially emphasized the importance of open standards, open source, and open data in building effective and resilient disaster management systems. - Download as a PDF or view online for free
