GeoDec: a multi-layered query processing framework for spatio-temporal data

Harnessing the potential of today’s ever growing and dynamic geospatial data requires the development of novel visual analysis interfaces, tools and technologies. In this paper, we present and demonstrate GeoDec, a generic framework capable of supporting queries and visualizations of realworld geospatial data sets. We show, for various locations and applications, how our innovative Query Driven Design enhances the visual analysis of geospatial data through the interactive manipulation of queries and query results. Categories and Subject Descriptors H.4 [Information Systems Applications]: Miscellaneous; D.2.8 [Software Engineering]: Metrics—complexity measures, performance measures General Terms Geospatial data, visual analysis, spatio-temporal interface. Keywords Geospatial, temporal, query, interface, architecture.
