Emerging Applications and Challenges for Geovisual Analytics Research

Brian Tomaszewski, Professor, CAST-CSM, RIT


Geovisual Analytics is a sub-paradigm within the broader visual analytics paradigm. Visual Analytics is concerned with how visual interfaces and other software components can be used to maximize human analytical reasoning capabilities [1]. Geovisual Analytics in particular “help(s) identify relevant geospatial information, data, and knowledge by supporting analytical processes that meld innate human abilities of vision and cognition with computer-based visual interfaces that provide flexible connections to relevant data and supporting knowledge, and that are specifically designed to provide support for analytical reasoning” [2:174]. The goal of systems designed within the Geovisual Analytics paradigm is to aid user reasoning processes directed to explaining evidence and to making evidence-based decisions, especially when potentially relevant evidence is scattered across unstructured and differing data formats. In this talk, Dr. Tomaszewski will discuss his Geovisual Analytic research experience on contextualizing humanitarian crisis situations as a platform for investigating emerging applications and challenges for the broader Geovisual Analytics research agenda.

Brian Tomaszewski is a Geographic Information Scientist whose research involves developing collaborative, web-based geovisual analytic tools to support human analytical reasoning with heterogeneous geographic information for contextualizing crisis situations. Brian has worked as a special consultant for United Nations ReliefWeb group developing geospatial applications for humanitarian information. He received a Ph.D. in Geography from Penn State. He is currently an assistant professor at the Rochester Institute of Technology.
