Abstract: New Research Directions of Internet GIS and Web-based GeoVisualization for the San Diego 2007 Wildfires

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.

Abstract : Visual Thinking and Geo-Spatial Data Visualization

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.

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).

He 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.

Abstract : The National Historic Geographic Information System (NHGIS): A Visualization of Space and Time

The National Historic Geographic Information System (NHGIS) is a five-year NSF-funded project designed to create a comprehensive U.S. census database–at the census tract and county level–for both the geographical and attribute data. Technological change presents an unprecedented opportunity to make these data readily available for social science research; thus bringing the complete census within reach of social scientists will unlock the potential of two centuries of data collection, and will stimulate research in economics, history, sociology, geography and other fields.

The project consists of three major components: data and documentation, mapping, and data access.

  • The data and documentation component gathers all extant machine-readable census summary data; fills holes in the surviving machine-readable data through data entry of paper census tabulations; harmonizes the formats and documentation of all files; and produces standardized electronic documentation according to the recently developed Data Documentation Initiative (DDI) specification.
  • The mapping component creates consistent historical electronic boundary files for tracts, minor civil divisions, counties and larger geographic units.
  • The data access component creates a powerful but user-friendly web-based browser and extraction system, based on the new DDI metadata standard. The system provides public access free of charge to both documentation and data, and presents results in the form of tables or maps.

This database will enable researchers to pursue many types of geodemographic analysis not possible before. Two additional research activities for the project include areal interpolation and cartographic generalization. We have now developed and tested a multitude of different interpolation algorithms that will allow researchers to make direct statistical comparisons across decades. For instance, a user might wish to calculate the percent change in poverty from 1960 to 1990 for Los Angeles. Research on the project is also exploring the creation of multiple scale databases at 1:150,000, 1:400,000, and 1:1,000,000 through the application of generalization algorithms. All boundary and statistical data will be delivered through a Web interface, and was made available in the summer of 2006.

Abstract : Visualizing Geographic Processes

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.
