“That is one cool thing about Landsat… people are always finding new applications.”

“Giant kelp forests are especially sensitive to environmental changes and have a history of undergoing abrupt, dramatic declines and increases in response to a variety of climatic and human-induced factors. The application of our remote sensing methods to the long-term (continuous since 1984), high frequency (~ once per month) global coverage of Landsat imagery is providing a unique opportunity for studying these dynamics over spatial and temporal scales that were previously impossible to e…

“Landsat is key to a wide range of applications that support global glacier monitoring and elucidate the impacts of global climate change.”

“The US satellite series—its current flier is named Landsat 8—pioneered the science of monitoring the planet from orbit. It has assembled a continuous record of the world’s fluctuating features that stretches back more than 40 years. In satellite terms, it is the gold standard.”

“It is a game changer for people who want to know the impact of a management action on particular piece of land, or how a dam affected the downstream area.”

“Land cover is fundamental for a plethora of applications. Approaches using #Landsat time series have been transformative.”

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

“Landsat has allowed managers to observe regional trends in kelp canopy area and biomass across more than 30 years. This is very valuable.”

“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 Hansen dataset, as we call it, produce…

“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.”

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

“The Landsat archive holds great potential for studying the processes behind the Greenland Ice Sheet’s response to our changing climate over multi-decadal time scales. It is essential that this record be exploited over other areas of the Greenland Ice Sheet.”

“Landsat 9 is really a land imaging cornerstone in guaranteeing that we’ll continue to have the types of surface measurements that we’ve had for nearly 50 years, and I think that’s significant. The user community that has developed science and application advancements around Landsat 8 will now get two observatories that are nearly identical, and we can expect to have a high-quality and reliable data stream for the next 10-plus years while Landsat continues to evolve into the future.”

“Landsat is providing better [surface] water data—not just at the state level or nationally, but globally”

“There is a sensor in the Landsat satellite which measures the intensity of the reflected radiation back into space. What if we could use satellite imagery from the Landsat program to find fossils?”

“It’s a treasure trove.”

“Landsat 8 is part of a revolution of how much remote sensing can do to track the polar areas.”

“By unleashing the power of our vast and open data resources, the Climate Data Initiative helps spark private sector innovation and will leverage resources for those on the front lines who are dealing with climate change. We are pooling into one place data from across the federal government to make it more accessible to the public and we hope our efforts will inspire other countries to follow suit.”

“During the decade following 1969, a singular development catapulted computer mapping: the launch of Landsat by NASA and the U.S. Department of the Interior in July 1972.”

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

“LANDFIRE is the only complete, nationally consistent collection of spatial resource datasets with an ecological foundation.”

“Tropical deforestation plays a big role in global climate cycles… without the transparency of Landsat satellite data is difficult to put your finger on changing trends.”

“You can launch a new satellite, but you can’t put something up in the past. Landsat will always be that historic record that new satellites can tie themselves to.”

“Because of Landsat’s global coverage and long history, it has become a reference point for all Earth observation work and is considered the gold standard of natural resource satellite imagery.”

The NASA/USGS Landsat Program provides the longest continuous space-based record of Earth’s land in existence. Landsat data give us information essential for making informed decisions about Earth’s resources and environment.
