The Landsat Program

This joint NASA/USGS program provides the longest continuous space-based record of Earth’s land in existence. Every day, Landsat satellites provide essential information to help land managers and policy makers make wise decisions about our resources and our environment. + Landsat Case Studies ebook

“The USGS’ incredible gift of open-source [Landsat] imagery and this kind of tool are truly advancing what non-scientists can expect when it comes to views of their planet. Never before have regular people had such ready access to geographic data at this depth and quality.”

“Landsat enabled us to collect a multi-decadal record of the [river] reaches at almost annual resolution. By extending our record into the past we were able to examine how the reaches changed through time providing us with a truly invaluable dataset.”

“When you have Landsat you can actually show people how we are changing the face of the planet.”

“It’s a treasure trove.”

“Since late 2008, when Landsat data was made available to all users free of charge, over 22 million Landsat scenes have been downloaded through the USGS-EROS website—and the rate of downloads is still increasing.”

“Landsat is the oldest continually operated program of its kind: Its satellites have been capturing images of the Earth since the Nixon administration.”

“An engineering degree opens many doors. It has served me well.”

“The primary archive available for reviewing the positions of coastlines and effects of sea-level rise is Landsat.”

“Without Landsat, ‘we would be flying blind. We need those eyes in the sky to complement our ground efforts.’”

““When the first images appeared, people would talk about the folds in the Appalachian Mountains. There had been textbooks written that described the processes that lead to those formations. For the first time it was possible to observe from great height what people had been talking about for hundreds of years.”

“The advent of Landsat data enabled an unparalleled increase in our understanding of the Earth system.”

“Landsat is currently the only satellite program to provide a consistent, cross-calibrated set of records stretching back over more than four decades, which in turn means the program occupies a key position in the provision of terrestrial essential climate variables.”
