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 VITOs 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
