The Platform for 3D Geospatial

We are thrilled to announce that Bentley Systems’ iTwin Ventures has opened applications for the next cohort of iTwin Activate with the theme of “Advancing Infrastructure with Cesium and 3D Tiles.” 

Editor's note: Cesium is committed to open source, open standards, and rapid innovation. We power training, planning, operations, and analysis across the US Department of Defense and Intelligence Community. We're proud to have collaborated with NUWC Division Newport and NSWC Carderock Division on this article about the impact of OTAs. Read the PDF here.

With the release of CesiumJS 1.130, users can drape imagery layers on 3D Tiles, allowing developers more freedom to combine geospatial data from different sources. Reality meshes, CAD/BIM data, and point clouds can be uploaded to Cesium ion and converted into 3D Tiles for efficient streaming and visualization. Now, imagery data like Bing Maps imagery or OpenStreetMap imagery can be layered on top, creating more powerful 3D geospatial applications. This addition addresses a long-standing community request and supports a wide range of use cases.

It’s been just over nine months since Cesium joined Bentley Systems. We’ve used that time to learn more about the technologies built by Bentley and opportunities to bring them to the community. As we look forward to the first Cesium Developer Conference, we are sharing our roadmap to seek your guidance as we bring iTwin digital twin capabilities to Cesium. 

We are excited to share that a geospatially accurate 3D Globe is now available in the open source platform QGIS as part of the QGIS 3.44 stable release. This development fulfills a critical need for QGIS users, enabling visualization of both 3D Tiles and other standard geospatial layers at global scale. This project is the next step toward greater access to 3D geospatial tools in QGIS. 

今回ご紹介するのは、大阪公立大学の金子健作博士による挑戦です。金子氏は建築物の耐震工学を専門とし、最近では、AIを活用した構造ヘルスモニタリング (SHM) を研究されています。SHMとは建物内に加速度センサを設置して、大きな地震の発生直後に建物の安全性を自動的に判定する技術です。このSHMの新たな展開に関して、金子博士はこのSHMシステムの普及を進めるために、3DのWeb GISで建物の安全性を可視化する新たなアプローチに挑戦しています。
