Platform Overview
Understand the CDT architecture — geospatial layers, BIM models, and the multi-scale data model.
Getting Started
Install dependencies, connect to a deployment, and load your first digital twin in minutes.
Open Standards
Built on CityGML, IFC, and OGC APIs. No proprietary lock-in — your data stays yours.
Collaboration
Multi-user sessions, comments, and shared views — built for interdisciplinary teams.
API Reference
Full REST and WebSocket API surface for integrating CDT data into your own applications.
Contributing
CDT is stewarded as a Canadian not-for-profit. Learn how to contribute code, data, or feedback.
Transparent
Foster trust and collaborative development through fully open source code and public roadmaps.
Multidisciplinary
Where we are today is evidence that we are stronger and smarter when we build together.
