Decisions 1 ? Where? How big? How many? Predicted conditions? Water supply? There are periods in an emergency where time is a critical factor and decision making can only be crudely aimed at saving lives. Where? How big? How many? Predicted conditions? Water supply?

First constellation implemented - DMC n Disaster Monitoring Constellation –5 - 7 satellites –Multispectral imager –600km swath width –32m ground sampling distance –Daily revisit n Novel international partnership –Each satellite owned by one nation

DMC partners Space partners Algeria Nigeria UK China Thailand Associate space partner Turkey Disaster relief partner Reuters AlertNet Aspiring space partner Vietnam Market evaluation partner ESYS

DMC Image size  A tile is the smallest unit.  2500 x 2500 pixels (approx 80 km x 80 km)  Ground size varies slightly dependent on position in swath. approximate scale only 80x80km tiles UoSAT-12  Onboard data storage  Sized for 11 minute downlink  Holds 24 tiles  Scenes of 4 tiles can be targeted 5 satellites – image tiles/day

What will the first DMC output be like? UoSAT-12: 32m 4-band (Paraguay) Deforestation Illegal crops? Flooding would show very clearly

Last Thoughts The Disaster Monitoring Constellation is going to be launched. It represents a new way. Do we want to talk with the stakeholders? The Disaster Monitoring Constellation is going to be launched. It represents a new way. Do we want to talk with the stakeholders? If we give active support (non-financial) to a CEHE~SSTL bid for research funds it may be possible to use DMC 1 technology to develop a system for data processing and interpretation that gives a timely view of major emergencies.
