ABSTRACT: Satellite remote sensing has been applied to a variety of emergency responses for predicting, monitoring and/or managing natural or man-made disasters locally, regionally and globally. It has demonstrated that satellite imagery is a great data source for quickly responding to different emergency events. However, due to technical limitations, satellite remote sensing still faces certain challenges in real-time data collection. This paper discusses current satellite remote sensing technologies, on-going international initiatives, and future developments for rapid data collection. General discussions and examples with respect to spatial, spectral and 3D capacities of satellite imagery vs. effectiveness of information interpretation for certain natural and man-made disasters will also be given, to provide an overall guideline for data selection for a given emergency event.
