Experiments with user centric GEOSS architectures

This paper describes the work being performed under a NASA Earth Science Technology Office (ESTO) Advanced Information System Technology (AIST) grant to develop a modular sensor web architecture which enables discovery and generic tasking capability for sensors, both space-based and in-situ. This effort seeks to demonstrate methods to facilitate interoperability and ease of use of a diverse set of sensors by hiding the details required to obtain sensor data, process the science data and deliver the science products. In particular, Web 2.0 and open geospatial consortium (OGC) Sensor Web Enablement (SWE) standard services are used. Thus, these capabilities serve to facilitate a user-centric approach to Global Earth Observing System of Systems (GEOSS). This work builds on previous sensor web efforts conducted at NASA/GSFC using the Earth Observing 1 (EO-1) and other satellites.
