Earth Observation User Case Study: Power of the Pixel - 1972 to 2021

Social scientists at the U.S. Geological Survey (USGS) Fort Collins Science Center – in collaboration with the USGS National Land Imaging Program – conduct Earth observation user case studies using qualitative research methods. Using standard scientific methods, they are better able to understand the variety of Earth observation users, including how they use and value

Eyes on Earth Episode 59 - Landsat 9 Ground System

The launch of Landsat 9 in September of 2021 represents a milestone for a joint USGS/NASA program that stretches back nearly 50 years. Landsat 9 will continue the legacy of unbroken, repeat Earth observations and contribute to our understanding of a changing planet. The primary USGS roles for Landsat satellites, which are built and launched by NASA, are to operate the

Earth As Art 3

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect in the infrared

Image of the Week - Dry Spell Depletes Northern California Reservoirs

A prolonged dry spell has sparked woes over water availability and wildfire in the western United States.

This stretch of northern California is heavily reliant on man-made reservoirs. The recent history of a single Landsat scene can serve to illustrate the ripple effects of those severely parched conditions. Water levels have dropped in Folsom Lake, Indian Valley

Eyes on Earth Episode 53 - Remapping Canada's Fire History

Mapping fire perimeters is important work. It guides post-fire restoration efforts, fire mitigation strategies, and helps track of trends in burn severity over time. In the past, many of Canada’s fire agencies relied heavily on techniques like sketch mapping, which estimate burned area without exact measurements. In the pre-satellite era, pilots would sometimes fly over

Image of the Week - 3 Decades of Lithium in Chile

If you're watching this video, you're probably using a lithium battery. Smartphones, tablets and laptops all rely on lithium metal to store energy. It comes from surface mines or brine ponds, found in places like Australia, China and the United States. One of the leading sources for this increasingly valuable resource is the South American nation of Chile.

Eyes on Earth Episode 52 – Tracking ‘Gray Ghosts’ with Landsat

The invasive species hemlock woolly adelgid is a threat to eastern hemlocks, filling some southeastern U.S. forests with what are called “gray ghosts” of the trees. Until recently, the insect had stayed in the southern part New York, but late last summer, an infestation was discovered in the Adirondacks. On this episode of Eyes on Earth, a New York university researcher

Landsat 8 Collection 2 image of the Menindee Lakes in Australia

The Menindee Lakes in the Far West of New South Wales, Australia, are seen in this Landsat 8 Collection 2 image from May 14, 2021, and is shown as a natural color composite using the red, green, and blue bands (Bands 4,3,2).

Located along the Darling-Baaka River, the series of naturally occurring shallow, ephemeral lakes were modified with regulating structures for

Eyes on Earth Episode 50 – Delaware River Basin

About 15 million people rely on the Delaware River Basin for drinking water, including residents of Philadelphia, PA, Camden, NJ, and Wilmington, DE. What might happen to the water supply if climate change and population growth continue unabated? How might that impact land cover and land use patterns? Those are the kinds of questions scientists at EROS looked to answer in

Image of the Week - Wildfires Burn in the Shadow of Mount Rushmore

In late March of 2021, just four miles from the edge of South Dakota's second-largest city, two wildfires sparked by human activity burned through a section of the Black Hills.

The Schroeder fire began on March 29. It was fueled by high winds and dry conditions, spreading rapidly across more than 2000 acres, forcing the evacuation of neighborhoods and businesses.
