The data sets derived from these observations have chronicled transformations on the planet's surface, ranging from urban sprawl to tropical deforestation, covering even the most remote regions of the globe. Scientists in the United States, supported by the National Aeronautics and Space Administration (NASA) and other agencies, have demonstrated the utility and societal benefits of the data in a wide range of applications, including community planning, crop monitoring, coral reef mapping, water-quality assessment, disaster management, and homeland security. Sadly, this is about to change.
