Modern methods of spatial data capture, analysis and representation signify new opportunities for emergency managers to reduce the risk of and increase the resilience to natural and manmade hazards. This thesis explores the development of a progressive emergency management strategy in a complex institutional space, combining the spatial veracity of GIScience with an innovative approach for simulating and communicating emergency egress. The impact that spatial resolution and representation have on emergency evacuation calculations is examined in an analysis of 2D and 3D GIS based network analyses, and 3D game-engine based simulations. The implications of space are further examined in situated mixed reality simulations that enable the visual analysis of virtual evacuees in real-world spaces. Finally, this research introduces mixed reality geovisualizations of multilevel space as a method to communicate evacuation plans and increase locational cognizance. These interfaces challenge the status quo and encourage a 21st century approach to emergency management.
