Sensor Webs are …
• Distributed Earth observation systems
• Comprised of
– Satellite and in situ sensors
– Data systems
– Models
• Dynamically configured to produce
products on demand
• By using emerging web technologies

Why Sensor Webs for Earth Science
• Enable eScience for Earth Observation
– Improve science products
– Improve science operations
– Enable collaboration
– Save operational costs

Earth Observation Sensor Web Uses
• Improve science operations
– Plan sensor flight paths for unmanned air & surface
vehicles
• Autonomous sensor management
• Workflow generation
– Design field campaigns
– Simulate mission designs (ala OSSE, the Observation
System Simulation Experiment)

Earth Observation Sensor Web Uses
• Enable collaboration and save operational costs
– Leverage multi-agency, international assets, eg. US
GEO, GEOSS/CEOS
– Reuse infrastructure enabling collaboration in totally
different domains such as fires and floods
– Reduce staff via automation

Technical Challenges
• Sensor hardware, software and network
architecture
– Power management, communications in constrained
environments
– Intelligent agents, autonomy
• Service Oriented Architecture (SOA) challenges
– Standards maturity and cross-standards
interoperability
– Extending SOA to space
– Service orchestration
– Data provenance and quality in dynamically
configured sensor webs
– Security
