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

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 8 sketch

“There should be no competition between satellite remote sensing and fieldwork, there should only be collaborations.”

“This is an example of something government can do well: investing in infrastructure that broadly benefits society, and provides a stable platform for the development of businesses and economic activity. Landsat is the data equivalent of the interstate highway system, a public good that has spawned a thriving for-profit remote sensing industry in the US and beyond.”

“When you have Landsat you can actually show people how we are changing the face of the planet.”

“Landsat sees the earth in a unique way. It takes images of every location in the world to reveal earth’s secrets, from volcanic activity to urban sprawl.”

“At Google, we use Landsat data on a daily basis.”

“We use Landsat 8 to document glacier velocity patterns on a mountain-range-wide scale. Mapping glacier velocity is facilitated by Landsat’s high radiometric resolution and precise geolocation.”

“Satellite imagery can help us get the biggest bang for our buck by targeting conservation initiatives in a specific window of time at key locations. Landsat is the longest running Earth observation satellite system we have, and free access to this data enables researchers to look at the effects of seasonality, climate cycles, and long-term trends in land-use change.”

“The economic value of just one year of Landsat data far exceeds the multi-year total cost of building, launching, and managing Landsat satellites and sensors.”

“You need decades of data to say that a change in kelp is due to climate change rather than other cyclical factors, with Landsat, we have those data.”

“The issue of forest disturbance could not have been addressed without our analysis of Landsat Time-series Stacks”

“This portal harnesses more than 37,000 images from Landsat archives, dating back to the early 1970s, to track changes in outlet glaciers over time.”
