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.[]

Advisory Panel Recommends Landsat Data Stay Free

Keeping Landsat data free and open is the right path forward, a federal advisory panel has concluded. []

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

“The community was very vocal regarding the value of a free and open data policy.”

“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.”

“Population in 1972… was around 4 billion people. When we launched Landsat 8 there was 7 billion people on the surface of the planet. Due to those factors our land use and land cover has changed dramatically and continues to change and we use the information and the images from the Landsat satellites to understand the change, to study the trends, and to predict the future.”

“Landsat provides wide coverage of the Himalayas for years with spatial and spectral quality, especially now, with Landsat 8 that has enhanced spectral resolution, which enables the monitoring of glacier state.”

“I would summarize Landsat 8’s science impacts in three ways: More data, better data, and improved, expanded applications.”

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

“To make accurate machine learning models of major crops, we needed decades of satellite imagery from the entire globe. Thanks to Google Earth Engine hosting the entire Landsat archive publicly on Google Cloud, we can focus on algorithms instead of worrying about collecting petabytes of data. Earth observation will continue to improve with every new satellite launch and so will our ability to forecast global food supply.”

“A new era of open-access satellite data has arrived. In 2008, The U.S. Geological Survey released for free to the public its Landsat archive, which dates back to the 1970s and is the world’s largest collection of Earth imagery.”

“The Landsat archives were the foundation of our study. Landsat unlocks the previous three decades’ of global river changes by recording these ‘natural experiments.’ We were able to quantify the degree of accelerated migration and channel widening caused by 13 cutoff events, estimate the amount of sediment released into the channel due to the cutoffs, and infer the physical processes driving river response to cutoffs.”

“Satellite data is revolutionizing the way we map the world and the way we understand the natural and anthropogenic processes acting on Earth.”
