A Service Oriented Framework for Animating Big Spatiotemporal Datasets

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

Chaining Data and Visualization Web Services for Decision Making in Information Systems

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

iSERVO: Implementing the International Solid Earth Research Virtual Observatory by Integrating Computational Grid and Geographical Information Web Services

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

Service Oriented Warning System for Detection of Abondened Object in Video Surveillance

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
