GEO AIP-2 Kickoff

Workflow

Service Orchestration - Sensor Access Services

• Example workflows:

– Multi-mission programming

– Fine dust forecast maps

– Flood monitoring

– Other examples: OWS-3, OWS-4 (SPS & WCTS)

• Supported Specifications:

– EO Profile for SPS (OGC 07-018)

– Sensor Observation Service

• Supports Multi-Mission programming request definition:

– Help the user to identify suitable missions associated to his/her need on the basis of :

• Mission technical capabilities;

• Capacity to perform acquisition combining several missions (patchwork solution).

– Help user to perform the order submission and to follow-up his/her order.

Multi-mission Programming

COMU – Multi-mission Programming

• Based on EO Profile for Sensor Planning Service

Fine dust (PM10) forecast maps

• Forecasts of fine dust (PM10) concentrations by neural network.

• Currently based on in-situ measurements at ±50 locations.

• Current maps are created by simple spatial interpolation (inverse distance weighting).

• Spatial coverage to be improved by incorporation of Aerosol Optical Depth (AOD) maps.

• Fusion of PM10 and AOD by VITO’s RIO interpolation model.

Flood Monitoring and SAR tasking

• Need for geographical data before, during and after flood events.• Radar imagery best suited but tasking is a lengthy process.

• Reduce time to acquire SAR imagery by triggering Tasking Feasibility Request based on in-situ water-level measurements or river basin model outcome.

• Alert from in-situ network will initiate a chain of events.• In situ data:

– Water level gauges on Ijzer bassin– Morecombe Bay (UK) Flood alerts

• EO sensors:– GetFeasibility for ESA sensors
