Since GoogleEarth at the latest it is generally accepted that geo imagery
is going to form an integral part of our Internet experience. Very large
arrays actually are a common data structure in many scientific
disciplines; well-known examples are 2-D satellite maps, 3-D x/y/t image
time series, 3-D x/y/z exploration data, and 4-D x/y/z/t climate
simulation results. A rapidly growing demand can be observed for Web
services on objects of multi-Terabyte and soon multi-Petabyte sizes.

 To address these challenges, array databases extend the traditional
database model with efficient support for such large arrays. Based on a
clear conceptualization of data structures and primitive operations,
efficient architectures have been proposed. 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.

In our talk we will present the state of the art of array databases. Based
on the example of our rasdaman system we will discuss conceptual modeling,
query support, evaluation and optimization strategies. Further, we will
inspect selected geo and life science applications. One particular case
study will be the new Web Coverage Processing Service (WCPS) standard
issued by the Open GeoSpatial Consortium, OGC.


  Peter Baumann is Professor of Computer Science at Jacobs University
Bremen where he teaches databases, Web services, and Software
Engineering. He holds a PhD from Tech. Univ. Darmstadt. His research
interest focuses on large-scale multi-dimensional array databases and
their application in earth and life sciences, Grid, e-learning, etc.
Prior to joining Jacobs in 2004, he was consultant with Softlab GmbH,
then Assistant Head of the Knowledge Base Research Group at the Bavarian
Research Center for Knowledge-based Systems, and founder and CEO of two
spin-off companies. He has authored and co-authored 60+ book chapters
and papers on raster databases and further fields, and holds
international patents on array databases. He has received a series of
national and international innovation awards for his work. He is member
of the Open GeoSpatial Consortium (OGC, where he is chairing three
working groups on raster services), of the Commission for the Management
and Application of Geoscience Information, and a founding member of
CODATA Germany.
