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

More than Naught: The “Z” of Where Land Meets Sea

Harnessing 30 years of Landsat data, a team of researchers from Australia has created the first 3D model of Australia’s entire coastline.[]

Landsat 8 sketch

“The rich history of Landsat (40+ years) enables not only change detection and trend analysis, but also provides a unique oppurtunity for hydrologic model calibration and validation as shown in this application.”

“We have mapped then analyzed the area of forest converted each year to industrial oil palm and pulpwood plantations from 2001 to 2016, looking mainly at land under company management – that is, concessions. We use LANDSAT satellite imagery to monitor the annual expansion of plantations. We combine this information with annual maps of forest loss also derived using LANDSAT satellites by Matthew Hansen’s research group at the University of Maryland. The Han…

“It’s a treasure trove.”

“You may have heard me say this before, but I firmly believe there are few topics more fundamental to study than the workings of our planet. The earth sciences aim to unravel how the lithosphere, atmosphere, hydrosphere, and biosphere operate—and how they operate together. It is a science of synthesis. And it’s one that needs to move forward, both because of the great service the earth sciences perform for society and the understanding of world-shaping pro…

“Satellite imagery can be used retrospectively, meaning that the data collected by satellites today will probably help solve issues we are not currently even aware of—an advantage which is invaluable.”

“While Landsat instruments are fundamentally just electro-optical transducers that ingest photons and eject a digital bit stream, this transduction relies upon the state of the art in numerous technologies including optics, precision electromechanics, detectors, advanced materials, cryogenics, and signal processing.”

“The Landsat series of satellites is a cornerstone of our Earth observing capability. The world relies on Landsat data to detect and measure land cover/land use change, the health of ecosystems, and water availability.”

“I saw more use of Landsat as the gold standard of calibration than I’ve ever seen in the past. Most of the commercial vendors I heard from called out Landsat as the gold standard. Even the European vendors called out Landsat, which I thought was unique.”

“Nothing is harder to image than the past. It is imperative that all Landsat observations are archived and made available to users.”

“We’re happy to see that the Agribotix imaging system performs so well when compared to Landsat 8, one of the highest quality land imaging satellite systems…”

“The data policy for Landsat was a paradigm shift for the world. There is no doubt about it.”
