Workshop Titles and DescriptionsThe Design of Service-Oriented Architecture (SOA) for Geospatial ScienceOrganizers: Xuan Shi (Georgia Institute of Technology) and Robert Raskin (Jet Propulsion Laboratory) Service-oriented computing integrates distributed data and computing resources over the network in the form of Web services. Web services, however, "have little value if others cannot discover, access, and make sense of them" [Foster, 2005]. Web service architecture renovation is a significant and urging theme in the mainstream IT in general, and in the GIScience community in particular, because the geospatial use cases and functions are much more complex than the simple business transaction models. A sustainable Web service architecture serves the GIScience community and enables the automatic and dynamic service discovery, matchmaking, composition and invocation. Cyberinfrastructure for GIScienceOrganizers: Dawn Wright (Oregon State University), Tim Nyerges (University of Washington), Robert Raskin (Jet Propulsion Laboratory), Lynn Usery (United States Geologic Survey), Phil Yang (George Mason) The term “cyberinfrastructure” (CI) is being used with greater frequency to refer to how the traditional modes of scientific research are being extended or replaced by advancements in information technology (e.g., geoportals, high performance computing, semantic integration, geomiddleware). NSF is ramping up CI funding, so what is the geospatial niche in this? This workshop will introduce the emerging topic of CI, facilitate further dialogue and strategizing (e.g., bringing geospatial CI more to the fore at NSF), discuss CI work in progress among colleagues, and ways forward for GIScientists (i.e., workplans for future collaborations, organizing proposal teams for upcoming NSF calls). Temporal GIS: the past 20 years and the next 20 yearsOrganizers: May Yuan (University of Oklahoma), Sean Ahearn (Hunter College), David Bennett (University of Iowa), Kathleen Stuart Hornsby (University of Iowa) After Langran and Chrisman published “A framework for temporal geographic information” in 1988, GIS research on time and temporal issues prospered. As a result, GIS packages have been developed with limited temporal capabilities. A fully functional temporal GIS, however, still eludes us. What were the research breakthroughs in the last 20 years? What are the remaining research challenges that must be addressed? What are the main opportunities for the next 20 years? This workshop will include sessions with keynote presentations, panel discussions, and breakout group discussions that address temporal GIS research in representation, analysis and modeling, and applications. Moving Objects: From natural to formal languageOrganizers: Nico Van de Weghe (Ghent University), Roland Billen (University of Liège), Bart Kuijpers (Hasselt University), Peter Bogaert (Ghent University) Years ago, the unavailability of robust geocomputational tools and the lack of georeferenced individual-level travel data hypothecated the research about moving objects. Nowadays, location-aware technologies allowing for collecting, storing and processing moving object data are abundant. However, still perspectives lie in transforming raw moving object data into relevant information, and in how to move in between natural and formal language. The workshop mainly includes the following topics:
Trends in Pervasive and Ubiquitous Geotechnology and GeoinformationOrganizers: Johannes Schoening (University of Muenster, Germany) , Brent Hecht (University of California at Santa Barbara (UCSB), USA), Antonio Krueger (University of Muenster, Germany), Martin Raubal (University of California at Santa Barbara (UCSB), USA), Michael Rohs (Deutsche Telekom Laboratories, Berlin, Germany) The aim of the workshop is to bring together researchers from various fields to discuss trends in pervasive and ubiquitous geotechnology and geoinformation and their impact on the day-to-day application of geography by consumers and geo-friendly industries such as tourism and education. Thanks to the rapid advancement of mobile technology and the increased prevalence of geographic data sets that have both global coverage and local detail, it has become possible to access and experience in new ways massive amounts of spatially relevant information about nearly anywhere in the world. In this workshop, we will discuss the issues (both human factors and engineering challenges) surrounding these context-aware systems. While we will include any research topic that relates either to geotechnology or geoinformation, we will focus on the theory behind and application of systems that successfully and rigorously combine the two. Computational Models of PlaceOrganizers: Stephan Winter (The University of Melbourne, Australia), Werner Kuhn (University of Münster, Germany), Antonio Krüger (University of Münster, Germany) Place is a central concept in human spatial cognition and communication. It also serves as the prototypical spatial reference in human, economic and cultural geography. This workshop surveys the recent discovery of the topic of place in more formal and computational directions of research, among them location-based services, gaming, human computer interface design, ontology, robotics and localization, social networks, gazetteers and georeferencing, vernacular geography, tagging and text mining, qualitative modeling of environments, modeling affordance, and modeling uncertainty. Information semantics and its implications for geographical analysisOrganizers: Ola Ahlqvist (The Ohio State University), Martin Raubal (University of California Santa Barbara), Angela Schwering (University of Osnabrueck), and Ashton Shortridge (Michigan State University) This workshop seeks to bring together scientists and practitioners that work in the intersections between semantics & ontologies, cognitive sciences, geostatistics & spatial analysis. Two overarching goals are to:
Example issues include: capture and representation of semantics, context effects, cognitive aspects, similarity metrics, and semantics-based geographical analysis. GeoSpatial Visual Analytics Organizers: Gennady and Natalia Andrienko (FhG IAIS), Piotr Jankowski (San Diego State University), Menno-Jan Kraak (ITC)
