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

Landsat 8 sketch

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

“We show governments across the world that it makes financial sense to release broadly and openly the data that the taxpayer has already paid for. It will build your economy, it is certainly good for transparent government and, it is a boon for capacity building and education.”

“It’s a fundamental resource for the Australian community. It’s used at local government level, state government level, and national levels. It’s our most important Earth-observing satellite with out a question in my mind.”

“Landsat offers a unique continuous record of the surface of the Greenland Ice Sheet over the last 40 years, no other mission would have been able to provide observations of ice velocity change over such a long time period.”

“There are more than 800 billion Landsat-derived pixels of land in our imagery. If we printed out just our Landsat-based world map at poster resolution, it would cover two acres.”

“By seeing in electromagnetic increments beyond the normal range of human vision, Landsat revealed whole new worlds hidden within the folds of a familiar world we thought we knew so well.”

“Having all of this [30 m] Landsat data available more or less globally since 1984 will keep glaciologists busy for some more years, if not decades.”

“Landsat represents a public good, Earth-observation infrastructure that allows everyone to study their respective land resources and their change over time.”

“We hope to accelerate innovation in climate research, humanitarian relief, and disaster preparedness efforts around the world by making Landsat data readily available near our flexible computing resources.”

“The Landsat satellites have provided an unprecedented volume of high quality medium-resolution imagery spanning more than 30 years. Without this record it would be exceedingly difficult to place presently observed changes in ice discharge into a longer-term context.”

“The growth of open satellite-image archives such as Landsat is leading to more sophisticated data products.”
