Method execution on a distributed image processing back-end

The rapid grow of both, the size of remote sensing data and the number of users in this field requires systems which are easy to use, platform independent and mighty. Currently, many users are not able to process or even access data the way they would like to. Utilizing upcoming technologies like WWW, Java and CORBA, we propose a distributed system that connects users, data bases and method bases. Latter ones help users to find an appropriate sequence of methods for processing, and incorporating a broker they schedule execution onto fast remote processing units (backends). We discuss design considerations concerning the interaction of the back-end with other system components, and strategies for effective job distribution.
