Landsat Technical Working Group meets in Florida
The USGS Landsat International Cooperator Network met for the Landsat Technical Working Group (LTWG) #32 meeting in Orlando, Florida USA during the first week of February.
LEAP: Landsat Extended Acquisitions of the Poles Imaging Plan
Landsat Extended Acquisitions of the Poles (LEAP) imaging plan is a Landsat special request data collection program for Earth's polar regions that include Antarctica, Greenland, and Arctic sea ice geographies. The LEAP program includes Landsat 8 and Landsat 9 observatories that operationally acquire spaceborne images of all Earth's land surface and near-shore coastal environments. These images are
Physics-based satellite-derived bathymetry (SDB) using Landsat OLI images
The estimation of depth in optically shallow waters using satellite imagery can be efficient and cost-effective. Active sensors measure the distance traveled by an emitted laser pulse propagating through the water with high precision and accuracy if the bottom peak intensity of the waveform is greater than the noise level. However, passive optical imaging of optically shallow water involves measur
2024 William T. Pecora Award Nominations Now Being Accepted
Until May 15, 2024
USGS-NASA Award Honors Excellence in Earth Observation
Two awardees recognized with the 2023 William T. Pecora Award for achievements in Earth remote sensing.
EarthNow! Landsat Image Viewer
The EarthNow! Landsat Image Viewer displays imagery in near real-time as Landsat satellites orbit the Earth. Along with the near real-time video stream, EarthNow! also replays acquisition recordings from previous Landsat overpasses. When Landsat satellites are out of viewing range of a ground station, the most recent overpass is displayed.
Image of the Week: Ice Routes in Finland Revealed by Landsat
Cloud-free satellite views of Lake Saimaa in Finland are rare in January. But this Landsat 9 scene, captured on January 4th, reveals over 200 miles of winter shipping lanes. The water vapor from 3 large wood pulp factories can be seen on this shoreline. One is located in Lappeenranta, where the ice route begins.Icebreakers in Finland often keep shipping lanes open through November and December,…
Landsat Acquisition Tool
The Landsat Acquisition Tool helps determine when the Landsat satellites acquire data over specific areas of interest, displaying the paths that were acquired on any given day.
Earthshots
The surface of the Earth is always changing. Some changes like earthquakes, volcanoes, floods, and landslides happen quickly, and other changes, such as most erosional processes, happen slowly over time. It’s often hard to see these changes from ground level. Earthshots shows you how satellite data are used to track these changes over time.
Landsat imagery of the Aral Sea from 1992 to 2020
An Example of the Aral Sea as seen by a Landsat 5 composite in October 1992 (left) and as seen by a Landsat 8 composite in September 2020 (right). Path:160, 161 and 162/Row: 28 and 29. Natural Color Landsat 5: (3,2,1), Landsat 8:(4,3,2). Visit the Landsat Missions Web Site to learn more about Landsat missions and products. This image is used in one of our How Do You Landsat (HDYL)…
