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

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

“Over the years, we’ve used the Landsat imagery to develop an incredibly accurate depiction of Earth and its changes over time, which we’ve published in Google Earth and Maps for use by billions of people worldwide.”

“The resolution of Landsat imagery and the size of the Landsat database enables critical insight for scalable, high resolution flood detection in several key ways… This increased resolution is particularly critical in urban areas.”

“We had to push the spatial resolution because we’re interested in humans.”

“It’s being able to go back in time for the same location, with the same program, that’s given us a tremendous amount of really valuable information… With Landsat we can do that because the archive is so rich.”

“In order to produce a rock outcrop map for the entire Antarctic continent, we required a freely available georeferenced multispectral dataset. The dataset needed to cover the high latitudes; be recently acquired; be of a high enough resolution to identify individual outcrops and geomorphological features; and have suitable coverage of the continent. On this basis, the Landsat 8 multispectral satellite data was chosen for analysis as no other platform met …

“Another landmark program within USGS is called Landsat… USGS made a decision…to be able to open up that data, make it free, and the scientific discoveries, the articles, the access, the utility of that data just went absolutely through the roof. So it’s been a really wonderful story about how opening up scientific data allows more discovery, gets people more excited… We really do try to put our data out there in a way that it is usable by the most a…

“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 8 imagery is an incredibly powerful resource. It is some of the most valuable open data produced by the US Government. Our partners rely on Landsat data for everything from evaluating droughts to tracking conflict.”

“The majority of tropical countries are using Landsat imagery as the primary source of information to support their forest change assessments.”

“From now on, we’re going to be able to track all of the different types of changes in glaciers – there’s so much science to extract from the data.”

“Many of our customers’ work couldn’t be done without Landsat.”
