When disaster strikes, lives can be saved with rapid access to data on land and sea conditions, maps of transport links and hospitals, weather forecasts, and information on socioeconomic variables. Delivering this information requires integrating a range of disaster-related data from diverse sources in friendly formats. After disaster strikes, integrated information can be pivotal in limiting future risks. “SERVIR,” for example, puts previously inaccessible Earth observation data to use in Central America. With internationally shared, standardized data from disparate data sets, people and communities throughout the region now benefit from timely predictions of hazardous weather and the first-ever regional air quality reports. In another breakthrough, satellites coupled with ground data can measure rainfall intensity, resulting in improved flood alerts, safer construction choices, and many other benefits.
