1 Real and Virtual Spaces Nicholas F. Polys, Ph.D. Peter Sforza Center for Geospatial Information Technology

2 We shape our buildings; thereafter they shape us. - Winston Churchill Is this still true today? but today we not only inhabit it, we create it the building is becoming dynamic, aware, and smart

3 Evolution of Space The investment in and lifecycle of a building is great Many stakeholders require different views on the same information, which changes Smart infrastructure Occupants are producers, not just consumers

4 Building Lifecycle Design Building Utilizing Maintaining Renovating Decades... Digital turnover should be expected

5 Realities of Space But is this a tenable state of affairs? Lost and incompatible data Paying for the same thing over and over Systems need maintenance Electrical Plumbing Security Image: Fraunhofer IGD

6 Stakeholders in Space Tenants Visitors Sponsors Functionality Efficiency Accessibility Security

7 Informatics of Space Silos of Excellence: No overarching information model Vendor lock-in BIM CAD GIS

8 Informatics of Space The digital building must evolve with the physical building and be connected to its environment (context) BIM CAD GIS INFORMATION FLOW

9 International Trends Efficiency throughout the lifecycle requires interoperability of data and systems Standards support mandated for public systems 3D Visualization and metadata Standards such as X3D provide the foundation for real enterprises: US NAVY Deustche Bahn Electricite de France (EDF)

10 Virginia Tech Research Center for Geospatial Information Technology (CGIT) Leadership in International Technology Development Spatial Data Infrastructure Standards for 3D Graphics (Web3D.org, ISO) Standards for Geospatial data and services (OpenGeospatial.org, OGC)
