Abstract:  This paper will describe the progress on a 3 year research award from the NASA Earth Science Technology Office (ESTO) that began October 1, 2006, in response to a NASA Announcement of Research Opportunity on the topic of sensor webs .  The key goal of this research is to prototype an interoperable sensor architecture that will enable interoperability between a heterogeneous set of space-based, Unmanned Aerial Vehicle (UAV) based and ground based sensors.  Among the key capabilities being pursed is the ability to automatically discover and task the sensors via the Internet and to automatically discover and assemble the necessary science processing algorithms into a workflow in order to transform the sensor data into valuable science products.  As an example, our first set of sensor web demonstrations, prototype science products useful in managing wildfires using such assets as Earth Observing 1, managed out of NASA/GSFC, a UAV based instrument, managed out of AMES and some automated ground weather stations, managed by the Forest Service.  Also, we are collaborating with some of the other ESTO awardees to expand this demonstration and create synergy between our research efforts.  Finally, we are making use of Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) suite of standards and collaborated with their testbed effort, thus creating valuable best practices dialogs with other OGC members.

This research will demonstrate and validate a path for rapid, low cost sensor integration, which is not tied to a particular system, and thus be able to absorb new assets in an easily evolvable coordinated manner.  This in turn will help to facilitate the United States contribution to the Global Earth Observation System of Systems (GEOSS), as agreed by the U.S. and 60 other countries at the third Earth Observation Summit held in February of 2005.

This paper will describe our efforts to date, our planned activities and the implications from our preliminary results.
