We describe an existing system that delivers customized remote-sensing data products to web-connected clients, and what more is required to support supervised, on-demand processing of the data. We discuss how such an architecture can be used for these purposes, and how it may interoperate with existing parallel SAR processing architectures, or with a GIS application server. Applications of such a system include agriculture, ecology, geophysics, glaciology and hazard-monitoring.Article Journalhttp://www.sciencedirect.com/science/article/pii/S0167739X9900038254dcce078580fe1368eeaf14
