Remote sensing derived datasets supporting disaster alert systems on multiscales via web services

This paper shows how remote sensing derived information about the human and physical exposure can be used to support disaster alert systems. The human and physical exposures are calculated from LandScan and GHSL datasets, respectively. In this approach, a multiscale alert system relies on Web services that offer information about the amount of population and infrastructure affected by a given hazard. Four natural disaster scenarios have been selected to cover different spatial scales and disaster types.
