Conference Program

All the workshops and tutorials will be in the Ohio Union at the Ohio State University, and the main conference will be in Sheraton Columbus Hotel at Capitol Square in downtown Columbus. The distance between the two sites is about 2.8 miles (4.5 km). Please see our transportation page for details.

An asterisk (*) or a paragraph sign (¶) indicates a 30-minute presentation; all other presentations are 20 minutes. We will use the Governor's Ballroom on the second floor for keynote speeches, lunch, and posters. All presentations will be in the four meeting rooms (Judicial, Executive, Legislative A, and Legislative B) on the first floor.

Noel Cressie: Hot Enough for You? Uncertainty Quantification for Regional Climate Projections in North America
Output from regional climate models (RCMs) can be very-large-to-massive. Several flavors of RCMs run for the same period only add to the data size. By modeling the RCM output spatially and statistically, uncertainties can be quantified, however dimension reduction is a practical imperative. In this talk, emphasis is placed on visual summaries of temperature increases from the North American Regional Climate Change Assessment Program (NARCCAP) and analogous summaries of samples from high-dimensional posterior distributions. This research is joint with Emily Kang of the University of Cincinnati.
Jack Dongarra: An Overview of High Performance Computing and Future Requirements
In this talk we examine how high performance computing has changed over the last 10-year and look toward the future in terms of trends. These changes have had and will continue to have a major impact on our numerical scientific software. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic, distributed and parallel environments. Some of the software and algorithm challenges have already been encountered, such as management of communication and memory hierarchies through a combination of compile--time and run--time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run--time environment variability will make these problems much harder.

Helen Couclelis: What Geographic Information Science is NOT: three theses
Geographic information science is not about geographic data (it is about geographic information) or about the real world (it is about representations of the real world). Together these two rather obvious theses lead to a third: GIScience is not a science (it is a metascience), which has interesting implications for the data age.
Douglas Richardson: Creating Spatial Infrastructure: Geographic Context, Data, and Analysis in Health Research
This talk addresses the landscape of research challenges and opportunities generated by three inter-related AAG health initiatives: 1) the AAG Initiative for an NIH-wide Geospatial Infrastructure for Health Research; 2) Geospatial Frontiers of Health and Social Environments (funded by NIH) and 3) Addressing Challenges For Geospatial Data-Intensive Research Communities: Research on Unique Confidentiality Risks & Geospatial Data Sharing within a Virtual Data Enclave (funded by NSF) . These AAG initiatives have generated linked and interactive research needs and agendas in the rapidly expanding domain of spatial technology, data and methods in health research. They have also created an increased awareness by health and biomedical researchers as well as by geographers of the core role that geography and GIScience can play in addressing global health needs, both in research and in practice.

Yee Leung: Issues of Scale in Spatio-Temporal Data Analysis
I will start off the speech with a notion of scale in general data clustering. Our discussion will then move to fundamental issues of scale and its handling in the analysis of temporal and spatial data. I will round it up with a look into the issue of scale in space-time integration in general and multi-scale data fusion in particular. Theoretical arguments will be substantiated by numerical examples and real-life applications.
Peter Bol: Spatializing History
Large-scale historical GIS systems now cover a significant part of the human population for centuries and millennia and historians are increasingly making use of geospatial analysis. Chinese history serves as one example. Further cyberinfrastructural developments have the potential to make GIS part of the research toolkit of all historians.
