Interactive Demos
Subsurface and BIM Data Visualizations
Explore real-world examples of subsurface and BIM data across different platforms. See ground investigation data in CesiumJS 3D maps, MapLibre, and Speckle. For free browser apps you can run on your own files, see our tools.
Kai Tak, Hong Kong - CesiumJS
Ground investigation data from Kai Tak, Hong Kong visualized in an interactive CesiumJS map. Borehole locations, SPT results, and weathering grades in 3D, transformed from AGS3 to GeoJSON with bedrock-ge.

Ten noorden van de Waddeneilanden - CesiumJS
The integrated ground model for Ten noorden van de Waddeneilanden, an offshore wind zone north of the Wadden Islands, rendered as 3D Tiles Voxels in CesiumJS. Geological units on a 25×25×0.1 m grid, from the quantitative ground model built by NGI and SAND Geophysics for the Netherlands Enterprise Agency (RVO).
