“In a world of scarce resources, there are distinct tradeoffs in costs and benefits of land use, and whether to conserve or convert forest to cropland. Map-based images are perhaps one of the most succinct means of helping policymakers digest complex ideas of social and economically driven environmental change.”

“The Landsat program provides an unparalleled historical record of coastal observations that captures how the world’s coastlines have changed over time in incredible detail.”

“Dai Yamazaki, a hydrodynamic engineer at the Japan Agency for Marine-Earth Science and Technology, calls the new [Landsat-based] imagery collection the best understanding yet of Earth’s changing surface water.”

“I have really appreciated being able to use Landsat data as a ‘time machine’ to understand our changing environment.”

“The resolution of Landsat imagery and the size of the Landsat database enables critical insight for scalable, high resolution flood detection in several key ways… This increased resolution is particularly critical in urban areas.”

“Science and reliable data need to be at the heart of policy decisions around the globe if we are to tackle climate change and other serious environmental challenges facing our world. It is vital that we share the trusted data that comes from Earth observation so citizens, scientists, and political leaders everywhere can most effectively work together to meet these most difficult challenges.”

“The first step of ecosystem accounting is to actually map the dynamics of ecosystems over time.”

“The Landsat data record is absolutely invaluable—wetland managers can start to understand if changes they are seeing take place over months, years or decades.”
