Paper Abstract

Recent years have witnessed the emerging Virtual Globe technology which has been increasingly exhibiting powerful features and capabilities. However, the current technical architecture for geovisualization is still the traditional data- viewer mode, i.e. KML-Geobrowser. Current KML is basically an encoding format for wrapping static snapshots of information frozen at discrete time points, and a geobrowser is virtually a data renderer for geovisualization. In the real world spatial-temporal objects and elements possess specific semantics, applied logic and operational rules, naturally or socially, which need to be considered and to be executed when corresponding data is integrated or visualized in a visual geocontext. However, currently there is no a way to express and execute this kind of applied logic and control rules within the current geobrowsing architecture. This paper proposes a novel architecture by originating a new mechanism, DKML, and implementing a DKML-supporting prototype geobrowser. Embedded programming script within KML files can express applied logic, control conditions, situation-aware analysis utilities and special functionality, to achieve intelligent, controllable and applied logic-conformant geovisualization, and to flexibly extend and customize the DKMLsupporting geobrowser. Benefiting from the mechanism developed in this research, geobrowsers can truly evolve into powerful multi-purpose GeoWeb platforms with promising potential and prospects.
