Latest in Landsat - April 2024 - Vol. 3 | Issue 4
In March, USGS leadership met with Australian officials and signed a joint statement for Australia's intention to join the Landsat Next satellite mission. A new Landsat Calibration/Validation report, the first containing Landsat 9 geometric and radiometric analysis, and a new Landsat Next factsheet were also published.

Calibration and Validation Quarterly Reports Now Include Landsat 9 Analysis
The USGS Earth Resources Observation and Science (EROS) Calibration and Validation (Cal/Val) Center of Excellence (ECCOE) focuses on improving the accuracy, precision, calibration, and product quality of remote-sensing data.
Landsat Next
Landsat Next's launch in the early 2030s will ensure continuity of the longest space-based record of Earth’s land surfaces. The mission will substantially increase the breadth and quality of Earth observation data available to scientists, land managers, and others responsible for managing Earth's natural resources. Landsat Next’s constellation of three satellites will carry sensors that improve bo
Monitoring polar ice change in the twilight zone
Landsat’s new extended data collection program is mapping Arctic and Antarctic regions year-round, even in polar twilight.
Landsat Helping to Address Food Security Challenges in Africa
Learning from the past and planning for the future. Using Earth observation products and tools in the fight to achieve global food security. This is the third in a series of four articles showcasing the socio-economic benefits of Digital Earth Africa and Australia products and services, through user case studies and impact stories.
2024 William T. Pecora Award Nominations Now Being Accepted
The William T. Pecora Award is presented annually to individuals or teams using satellite or aerial remote sensing that make outstanding contributions toward understanding the Earth (land, oceans, and air), educating the next generation of scientists, informing decision-makers, or supporting natural or human-induced disaster response. Both national and international nominations are welcome.
Von Karman Vortices in the Atlantic (Image of the Week)
On March 3rd, near South Georgia and the South Sandwich Islands, Landsat 9 captured this dream-like image. This natural color view shows a weather pattern known as a “Von Karman vortex street," caused by prevailing winds from the southeast. A vortex street is a fluid dynamics pattern that describes the chain of swirling clouds created when air passes a volcano, mountain or island. These patterns…
Historical Landsat-Derived Water Surface Temperature for Three Large Alaska Rivers 1984-2022
This data package includes 17,014 pairs of raster geotiffs. Each pair is made up of two geotiff rasters derived from historical observations from Landsat satellites (04-09) over the Yukon, Kuskokwim, and Tanana rivers in Alaska. One raster reports estimated mid-day water surface temperature (ST) in degrees Celsius (deg_Cc). The second raster reports the surface temperature quality assessment (sST_
Landsat 9 Image Captures Iceland Volcano Lava
In November 2023 the Svartsengi volcanic system awakened after almost 800 years with a series of earthquakes that opened large cracks in the on Iceland’s Reykjanes Peninsula. An eruption on December 18th spewed lava away from the nearby coastal town of Grindavik, but the January 14, 2024 eruption sent lava directly toward the town. A third eruption began February 8th,…
Eyes on Earth Episode 115 – EROS Women in Science
To celebrate Women’s History Month, we gathered some of the women who have made a difference in science at EROS.
Spectral Characteristics Viewer
The Spectral Characteristics Viewer allows users to determine which satellite bands are best suited for research applications.
Eyes on Earth Episode 114 – The Color of Water with Landsat
Typically, we use Landsat data to study changes on the land—you know, Landsat. In this episode of Eyes on Earth, we learn how satellite images and pixels of water, along with actual water samples, are helpful in determining the productivity of lakes across the United States. We talk with Mendenhall Fellow and Research Geographer Dr. Michael Meyer about a recently released, freely accessible…
SpatioTemporal Asset Catalog (STAC)
The SpatioTemporal Asset Catalog (STAC) family of specifications helps standardize the way geospatial metadata is structured and queried.
This page describes many STAC components - a browser, an API, samples, and tutorials. Review each section below to learn all about STAC.
