Interactive Demos
Ground Investigation Data Visualizations
Explore real-world examples of ground investigation data transformed into interactive visualizations across different platforms and tools. See how ground investigation data can be visualized in CesiumJS 3D maps, Speckle BIM integration, and ArcGIS Pro.
Web-Based Visualizations
Kai Tak, Hong Kong - CesiumJS
Ground investigation data from Kai Tak, Hong Kong visualized in an
interactive CesiumJS map. Explore borehole locations, SPT results,
and weathering grades in 3D context directly in your browser.
Source data transformed from AGS3 format to GeoJSON using
Explore demo → bedrock-ge for web visualization.
GEF File Viewer
Free web-based viewer for GEF (Geotechnical Exchange Format)
files. Upload and visualize CPT & bore data directly in your
browser.
