"Integrating Online and Geospatial Information Sources"
Craig Knoblock, Information Sciences Institute, University of Southern

With the explosive growth of the Web there are now a huge number of sources of data available online, including geospatial sources with maps and imagery and an even larger number of sources with data that can be placed into a geospatial context. The challenge is how to make effective use of all this data by integrating the data across diverse source types. In this workshop, I will describe the techniques that we have developed for exploiting online sources, including turning online sources into structured data, linking records across different sources, planning to dynamically compose sources, and efficiently integrating sources in a networked environment. I will also describe techniques for integrating online sources with various geospatial data sources, including using online sources to automatically conflate vector data with imagery, identify buildings in imagery, and predict the location of moving objects (e.g. trains) along fixed trajectories.
