Abstracts and Short Bios for GeoVisualization Colloquia Speakers

Dr. Ming-Hsaing Tsou

Internet GIS is the cyber-infrastructure framework for geographic information services, which utilize both wired and wireless Internet to access geographic information, spatial analytical tools, and GIS web services. This talk will introduce the concepts, technologies, theories, and future research directions of Internet GIS and Web Mapping Services. Clearly, the progress of Internet GIS implies an invisible revolution of GIS -- from closed, centralized geographic information systems to open, distributed geographic information services. The development of Internet GIS will encourage people to share geodata, exchange GIS programs, and accumulate the knowledge of geographic information science. Internet GIS provide a brand-new view for geographers, urban planners, GIS professionals, and scientists to analyze and represent our world.

Recent wildfires in southern California demonstrate the need of creating new research focuses of Internet GIS and GeoVisualization. Disaster management (or emergency management) is unique among Internet GIS applications because it deals directly with loss of human life and property damage. Disaster management is a complex domain of human activity involving multiple agencies and stakeholders. A collaborative approach utilizing state-of-the-art Internet GIS and mobile GIServices can facilitate a comprehensive and functional disaster management plan. This talk will also address the experiences we learned when applying Internet GIS and Web mapping services for the recent San Diego 2007 wildfires. During the wildfires, we realized that some Web mapping technologies are useful, and some are not. There are still some major challenges in the development of Internet GIS and Web mapping services for disaster management and responses.

Ming-Hsiang (Ming) Tsou is an Associate Professor in the Department of Geography, San Diego State University. He received a B.S. from National Taiwan University in 1991, an M.A. from the State University of New York at Buffalo in 1996, and a Ph.D. from the University of Colorado at Boulder in 2001, all in Geography.

His research interests are in Internet mapping and distributed GIS applications, mobile GIS and wireless communication, multimedia cartography and user interface design, and software agents with GRID computing technology. He has applied his research interests in applications such as wildfire mapping, environmental monitoring and management, habitat conservation, and homeland border security. He is co-author of the book, Internet GIS: distributed geographic information services for the Internet and wireless networks.

Dr. Tsou was the co-chair of the NASA Earth Science Enterprise Data System Working Group (ESEDWG) Standard Process Group (SPG) from 2004 to 2007. He is a member of the Association of American Geographers and the American Congress on Surveying and Mapping. Dr. Tsou is currently the Chair of the Cartographic Specialty Group in the Association of American Geographers (AAG) and the Webmaster for the Geographic Information Science and System (GISS) Specialty Group in AAG.

He received the 2004 Outstanding Faculty Award at San Diego State University. Dr. Tsou was recently listed in Marquis Publishing Who's Who in America in 2006, 2007, and 2008, and was appointed by the National Academy of Science to serve on the committee on "Research Priorities for the USGS Center of Excellence for Geospatial Information Science" in 2006. In 2007, Dr. Tsou created and maintained an interactive Web-based mapping services for San Diego Wildfires 2007 and his efforts have been recognized by the AAG newsletters and the San Diego Union Tribune (newspaper).

Geo-spatial data visualizations are interactive visual thinking tools help us extract meaning from data through process of visual pattern search. This talk will begin with an overview of visual thinking considered as an active process involving visualizations as well as the more usual cognitive constructs such as visual working memory. I will give three examples that show how the application of elementary cognitive theory can help us explain large differences in the efficiency of user interfaces. The first example addresses the question of when extra windows are needed in a geospatial visualization interface. The second example is an interactive system designed to allow reasoning with much larger network diagrams than can be normally be displayed a screen. The third example is based on the interactive graphical tools we have developed to analyze data obtained from tagged humpback whales. From this last example I will make the case, based on simple active vision-based arguments, that turning time varying data into spatial patterns is almost always the right thing to do. My broader goal will be to argue we need a kind of cyborg psychology in which both cognitive tools and the human brain are considered as a cognitive systems.

Colin Ware is Director of the Data Visualization Research Lab - which is part of the Center for Coastal and Ocean Mapping at the University of New Hampshire. Ware has a special interest in applying theories of perception to the design of geospatial data interfaces. He has advanced degrees in both computer science (MMath, Waterloo) and in the psychology of perception (PhD,Toronto).

has published over 120 scientific articles ranging from rigorously scientific contributions to the Journal of Physiology and Vision Research to applications oriented articles in ACM Transactions on Graphics and Transactions on Computer-Human Interaction. His book Information Visualization: Perception for Design is now in its second edition. His new book, Visual Thinking for Design, is about to appear. Ware also likes to build practical visualization systems. Fledermaus, a commercial 3D geospatial visualization system widely used in oceanography developed from his initial prototypes.

The digital revolution has changed how we make maps, how we use them, and how we think about them. Dynamic geospatial systems are increasingly integrated throughout the research process and allow experts to think through complex problems visually. One of the guiding principles of geovisualization is that users must be allowed to freely explore complex geographic data both to confirm existing hypotheses and to formulate new ones. In the last ten years there has been an explosion of available geospatial data. What remains is the challenge of turning these data into useable information. The use of interactive maping systems spans a conceptual space from private, exploratory knowledge construction through interactive public presentations. This field has emerged as traditional disciplinary boundaries blur, drawing on work in GIS, cartography, remote sensing, computer science, semiotics, cognitive science, and software engineering. Examples of prototype geographic visualization systems and mapping techniques will be demonstrated, including the latest approaches to representing uncertainty and error in geospatial data, dynamically linked statistical and cartographic systems, tools for exploring the impact of temporal and spatial scale, and 3D map animation.

Mark Harrower is an Assistant Professor of Geography and Associate Director of the Cartography Lab at the University of Wisconsin-Madison. His current research interests include perceptual and cognitive issues in map animation (in particular, 3D maps), interface design for maps, developing Web-based mapping tools and services, and critical cartography/GIScience. Mark also serves on the editorial board of Cartographica, CaGIS, Cartographic Perspectives, and Blackwell Compass and is an active member of the ICA Commission on Visualization and Virtual Environments, the Cartography Specialty Group of the AAG, and the North American Cartographic Information Society.
