Content transcoding middleware for pervasive geospatial intelligence access

Abstract

In this paper, we describe a novel content transcoding middleware for accessing military geospatiall intelligence information in real-time. Intelligence information, including maps and location, category and properties of object targets, is adapted for various pervasive devices such as laptop, personal digital assistance (PDA), cellular phone, etc. The middleware is deployed as proxies on the Web using the IBM Websphere Transcoding Publisher (WTP) platform, which facilitates the middleware management. We developed several Java-based plug-ins and Extensible Stylesheet Language (XSL) stylesheets for content transcoding. A prototype has been established and real experiments have demonstrated the effectiveness of this novel middleware.
