We propose a service oriented distributed system framework for animating big spatiotemporal vector datasets. The aim is exploiting the patterns in spatial data dynamically changing over time. Animation consists of succes- sively played and temporally related still map images. Each map image in the animation is a satellite map enriched with (or plotted over) spatiotemporal … Read more
Abstract. Decision making in information systems increasingly relies on analyses of data in visual formats which are created from distributed heterogeneous data belonging to the separate organizations. This paper presents distributed service architecture for creating and managing the production of knowledge from distributed collections of data sources through integrated data- views. Web Services provide key … Read more
Abstract—We describe the goals and initial implementation of the International Solid Earth Virtual Observatory (iSERVO). This system is built using a Web Services approach to Grid computing infrastructure and is accessed via a component-based Web portal user interface. We describe our implementations of services used by this system, including Geographical Information System (GIS)-based data grid … Read more
Large scale Geographic Information Systems (GIS) require experts from different areas, such as data maintenance and handling, data rendering and displaying, and data processing. However, it is challenging to host data, processing capabilities, and experts in the same geographical location. To enable remote coupling of these data and processing services, interoperable distributed system architectures have … Read more
Abstract— Video surveillance systems have been used in various applications such as traffic monitoring, detecting military threats and public safety. In this study we present a service oriented real-time automated framework to detect both abandoned objects and video tampering attempts. The technique is based on foreground and background analyses of the images in the videos … Read more
