The ways in which remotely sensed data can be used to manage and alleviate the consequences of natural disasters have never been fully exploited. If prediction of impending disaster is to be useful, those affected by catastrophe and those who come to their aid must work together. A global strategy based on a vision for disaster management will fail if those affected by hazards are not involved in their own disaster preparation, relief efforts and rehabilitation. Local people are experts in ground knowledge; all that is needed is for those with expertise in remote sensing to pass on their skills, knowledge and data in a way that can be understood and valued. To do this, those threatened by catastrophe must understand how disaster relates to their lives, how satellite data can be used with confidence to prepare for local hazards and how to apply information that can help lessen the effects of catastrophe. This can be achieved by making available remotely sensed images with simple explanations that enhance vegetation, topography and geology. With timely, reliable information, preventive measures can be taken; surface features identified on satellite images can guide refugee placement and hazards can be anticipated and contained.
