Interoperability allows a Common RealityInteroperability allows a Common Reality
“What we are doing is facilitating a common picture of reality for different organizations which have different views of the reality, the disaster, the emergency, the catastrophe, that they all have to deal with collectively”

What is SensorML?What is SensorML?
• Models and XML encodings for describing processes– Detectors, actuators, etc. are modeled as processes– Can be used to describe “left-side” processes (“how were these
observations obtained?”) and “right-side” processes (“what can I derive from these observations?”)
• Vision:– Discovery of transducers and processes / plug-n-play sensors –
SensorML is the means by which sensors and processes make themselves and their capabilities known
– Observation lineage – SensorML provides sensing and processing history of observations; supports quality knowledge of observations
– On-demand processing – SensorML supports on-demand derivation of higher-level information (e.g. geolocation or products) without a priori knowledge of the sensor system
– Extensibility – SensorML provides easy means for meeting various community needs

SensorML ExamplesSensorML Examples
• Video Web Cam - sensor system illustrating the ability to modularize descriptions between various components
• CEOS CalVAL Satellite Sensors - European Space Agency (ESA) and Committee for Earth Observation Satellites (CEOS) SensorML profiles (RelaxNG), instances, and documentation for standard satellite sensor descriptions.
• Tigershark UAV video camera - fairly complete description of a high-definition video camera on-board an Unmanned Air Vehicle (UAV).
• Davis Weather Station - Example description of a weather station.• CBRNE Gamma Detector - Simple HPI 2070 Gamma detector.• Marine CTP Buoy Sensor - An SBE 37-SMP MicroCAT Conductivity-
Temperature-Pressure sensor mounted on a buoy by the Monterey Bay Aquarium Research Institute (MBARI).
• CSM Frame Sensor Model - Community Sensor Model (CSM) based Frame Sensor Model for geolocating imagery from GSI KCM-39 video camera.
SWE Standards Current Status – June 2010SWE Standards Current Status – June 2010
• Current specs are in various stages (V1.0 specs approved 2007)
– SensorML/SWE Common – Version 1.0.1 (V2.0 underway)– Observations & Measurement – Version 1.0 (V2.0 underway)– WNS – Request for Comments– SOS – Version 1.0 (V2.0 underway)– SPS – Version 1.0 (V2.0 underway)– SAS – Ready for final vote (may skip V1.0 for V2.0; may incorporate
into SOS and Event Service)

Interoperability is about OrganizationsInteroperability is about Organizations
“Interoperability seems to be about the integration of information.
What it’s really about is the coordination of organizational behavior.”
