An uncrewed aircraft system (UAS) carrying a gamma ray spectrometer sensor sits on a landing pad at the Grand Junction Regional Airport (GJT) in Grand Junction, CO. USGS conducted UAS flights at a variety of transect spacings, altitudes, and directions over radioelement calibration pads built into the tarmac at GJT in support of critical mineral research.

A USGS remote pilot secures a gamma ray spectrometer sensor onto an uncrewed aircraft system (UAS) at the Grand Junction Regional Airport (GJT) in Grand Junction, CO. Concrete pads built into the tarmac at GJT contain known concentrations of naturally occurring radioactive materials including Potassium, Thorium, and Uranium for radiometric calibration.

The 3D Hydrography Program continues to make incremental progress. Notable progress has been made, including the release of HydroAdd3D as both an API and a web interface, the availability of Flow Network Derivative attributes in the 3DHP service, and on-going publication of new 3DHP data, including hydro-enforced DEMs.

Can you guess the locations of these mystery Landsat images?
Landsat satellites capture images of the Earth’s surface and help scientists study resource management, investigate land surface change, and support disaster response.

The Yellowstone National Park area has more than 10,000 thermal features. And while Old Faithful is a pretty predictable geyser, some thermal features can change quite a bit. New ones can even pop up! Remote sensing provides a tool for monitoring them—especially the thermal infrared sensors (TIRS) on Landsat 8 and Landsat 9 satellites.

Landsat has been accurate and reliable for over 50 years because of the diligent calibration and validation work done by the team at EROS. One of the ways the team validates what they have so carefully calibrated is to take measurements on the ground while Landsat passes by overhead.

Exotic annual grasses, or EAGs, are invasive species. They outcompete native grasses. They are extremely flammable. And they are expanding into higher elevations. Targeted sheep grazing is one way to combat these invasive grasses, manage fire risk, and help restore native sagebrush in western states.

Landsat is the longest-running, continuously operating record of Earth observations, and it’s the gold standard reference point that other civil and commercial satellite programs trust.

Declassified spy satellite imagery, distributed by the USGS EROS Center, is finding fascinating uses since being made available to the public starting in the 1990s.

Eyes on Earth tackles artificial intelligence (AI) in a 2-part episode. AI is quickly becoming a necessary part of geospatial work at EROS, helping us efficiently do science to better manage our world. In Part 1, we talked about AI’s current and upcoming impact on our work at EROS and clarified some of the AI jargon.
