Acquiring data, a task central to science and engineering, in many cases results in raster data; examples include 1-D environmental sensor data, 2-D satellite image archives, 3-D CAT scans, 4-D climate simulation results.
It is, however, a challenge in itself to set up Web services that allow integrated, open access to the vast amounts of data gathered. In the past, domain-specific solutions have prevailed; recently, a trend towards integrated data services using off-the-shelf database technology can be observed. To some extent driven by geo services, an emerging trend is to not just offer navigation and extraction facilities, but advanced server-side analysis and processing. This poses new challenges on data management and, in particular, the design of open, interoperable services.
In this tutorial we show how semantic Web services for large-scale, multi-dimensional raster data can be built using standard database technology, enabling for raster services ranging from simple, fast navigation to ad-hoc online analysis and mining. "Very large" here is understood as having single objects of multi-Terabyte to Petabyte size.
The tutorial will give an introduction to raster services, addressing modeling, architecture, optimization, and storage management. High emphasis will be devoted to applications in geo, life science, and the Grid; to this end, real-life use cases will be presented and discussed which stem from both projects carried out and our standardization work in the Open GeoSpatial Consortium (OGC, www.opengis.org).
The tutorial's objective is to introduce to the emerging field of open, large-scale, multi-dimensional raster services, and give a condensed overview on techniques, issues, standards, and applications.
The tutorial is designed for an interdisciplinary audience and offers insights for both novice and expert level. Some basic background about data management and Web services is advantageous.
The tutorial will take place on Sunday, 22 October 2006, 10:00 in China Resources Hotel Beijing (Beijing Huarun Hotel). It will have a duration of 3 hours, covering the following topics:
Dr. Peter Baumann is Professor of Computer Science at International University Bremen and founder and CEO of rasdaman GmbH, a research spin-off specializing in large-scale raster servers. Previously he was lecturing at the University of the Armed Forces Munich, and was Assistant Head of the Knowledge Bases Research Group at the Bavarian Research Center for Knowledge-Based Systems.
Peter Baumann's core research interest is large-scale multidimensional raster services and their application in geo, life science, Grid, and e-learning. He has published more than 50 book chapters and journal/conference articles in the areas of raster databases and their applications, graphics databases, CAD databases, and algebraic specification. He holds international patents on raster database technology and has received numerous national and international innovation awards for his work, such as the European IT Prize.
In the Open Geospatial Consortium (OGC) standardization body he works on refining and extending the Web Coverage Service (WCS) standard. Further, he is member of CODATA Germany, of the Commission for the Management and Application of Geoscience Information (a Commission of the International Union of Geological Sciences), and of national geo data bodies. Earlier he has been member of the OHBM (International Organization of Human Brain Mapping) Task Force on Neuroinformatics and of the EC-US Steering Committee on Neuroinformatics.
