title Topology of Urban Environments: Graph construction from multi-building floor plan data
source Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 115-128
summary This paper introduces a practical approach to constructing a hybrid 3D metrical–topological model of a university campus or other extended urban region from labeled 2D floor plan geometry. An exhaustive classification of adjacency types is provided for a typical infrastructure, including roads, walkways, green-space, and detailed indoor spaces. We extend traditional lineal techniques to 2D open spaces, incorporating changes in elevation. We demonstrate our technique on a dataset of approximately 160 buildings, 800 floors, and 44,000 spaces spanning indoor and outdoor areas. Finally, we describe MITquest, a web application that generates efficient walking routes.
