TRANSCRIPT
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
