The workshop begins with IFC model preparation using BonsaiBIM, where participants will learn to create or modify an IFC model enriched with precise geospatial data, including longitude, latitude, and elevation and potentially export the geometry to glTF for web integration. Next, the focus shifts to spatial data transformation in the free and open-source software QGIS, where attendees will position the IFC models, match building footprints, and convert digital elevation models (DEM) into GeoJSON for topoline data.
The final phase introduces web visualization using Maplibre, an open-source mapping library. Participants will set up their development environment using VS Code, integrate GeoJSON layers for 3D mapping, and render 3D terrain and building models using glTF. Additionally, the workshop will demonstrate the integration of Open BIM Components (OBC) from That Open Company, leveraging standardized templates to load and visualize glTF terrain meshes and IFC in a web-based environment.

Learning Outcomes:
This hands-on workshop offers a comprehensive exploration of cutting-edge workflows for integrating Building Information Modeling (BIM) and GIS using exclusively open-source tools. Designed for professionals and enthusiasts in architecture, engineering, and geospatial fields, this half-day session will guide participants through integration of BIM and GIS data, from desktop preparation to web-based visualization.
By the end of the workshop, attendees will gain practical skills in geospatial data manipulation, cross-platform BIM-GIS integration, and modern spatial technology workflows. This session is ideal for those looking to bridge the gap between architectural modeling and geographic information systems, empowering them to harness the potential of open-source tools for innovative spatial solutions.

Keneth Percy
Ph.D. candidate at Carleton University
Ken Percy studied architecture at Carleton University in the Azrieli School of Architecture & Urbanism, and is currently preparing to defend his PhD. His current work at CIMS is dedicated to exploring two unique, but interrelated themes: the creative potential of machine code for architectural design via digital fabrication, and the development the GIS integration of Canada’s Digital Twin platform.
