NEAR REAL TIME DATAFLOWSingle drop of information
Highest allowed detail

One streamof information(O3, NOx,CO2,PM10)

One place in space

One moment in time

NEAR REAL TIME DATAFLOWCURRENT NEAR REAL TIMEDATAFLOW•Widely use of properitary dataformats•Every dataflow needs specific development•Develop and maintainance cost are high•Data provider have to develop and maintain•Data receiver have to develop and maintain•Domain specific development

Increased demand for near real time data
More data required ‐ high quality
Quality control
More timely data
More efficient monitoringHigh level of interoperability
Integration between in‐situ and satelliteData re‐use
Higher efficiency
Thematical independency
Improved and flexible accessLess ressources to maintain multiple flows
SEIS compliancy

OZONE WEB•Since 2006
•1200 stations•70 data providers•30.000 measures per day•Near real time data ‐ hourly

EYE ON EARTHWatches•Waterwatch•Airwatch•Noisewatch•Climatewatch ?
•Naturewatch ?
•...

Data source•Near real time airquality data
•Seasonal waterquality•Historical waterquality•User rating

WHAT KIND OF OBSERVATIONS?
•Air quality•Water quality•Water level•Water quantity•Noise•Traffic•Forrest fire•Bouys (waves, wind, current)•Biodiversity•Ice cap monitoring•Human sensors?

WHERE TO GO• Standardise Near Real Time observation data system• Improve the way we handle NRT observation data
• Use SOS to exchange and expose NRT observation data
• Make the GIS industry support SOS• Better access to NRT observation data through services

WHAT IS SENSOR WEB?
SWE ‐ Sensor Web Enablement :•SOS ‐ Sensor Observation Service•Exchange and query observation data
•O&M – Observations & Measurements•SensorML – Sensor Model Language•SES –Sensor Event Service (SAS v.2)
•SPS ‐ Sensor Planning Service•TML ‐ Transducer Model Language•WNS – Web Notification Service

SOS NETWORK•No direct communication with sensors•Communication on service / database level

LOW COST SENSOR NETWORKS
Cheap, simple data acquisition
Reliable?
Is this a way to improve datacoverage?
Combine with existing network?

LOW COST SENSOR NETWORKSEEA demonstration sensor•Strengths•Weaknesses•Calibration issue•Learn what they can and can’t doLOW COST SENSOR NETWORKSEEA demonstration sensor
sample output; NO2, CO2, O2
Plan to make test data
available as SOS nodeNote: Sensors not calibrated

SOFTWARE SUPPORT•Minimize software development – industry support•ESRI•SOS to be supported in ArcGIS Server•First implementation as Server Extension
Object developed by 52North.org•Implementation supported by ESRI•Open source software available from 52North.org•MapServer ?
•Openlayer (client access)•...

?

SUMMARY•Common platform for observation data is needed•Need a service oriented approach•Need industry support to get SOS going•SOS based NRT platform parallel to Reportnet•SOS should be a benefit – not a burden•Pramatic approach to implement SOSQUESTIONS?
