Based on research originally undertaken at the Dalhousie University Libraries, this paper explores how evolving 3D visualization techniques-such as 3D printing, 3D scanning, holographic projection, and 3D animations-can be used to enhance and extract information from GIS-based map and geography. This paper provides an overview of these technologies, how these technologies could be of benefit to libraries, and the Dalhousie University Libraries successes and failures working with 3D city models and 3D printing and 3D scanning technologies, and offering these technologies to faculty and students.
