LCMAP - Time of Spectral Change & Spectral Change Magnitude

An overview of LCMAP Collection 1 science products: Time of Spectral Change, and Spectral Change Magnitude products.

LCMAP Collection 1 science products include ten science products offering different perspectives and ways to study land change across the country through time. While each product can be used separately, they are complimentary and inform one another.

Image of the Week - Glacial Changes in Chile

The remote ice fields of southern Chile have seen some dramatic change over the past three decades; change made clear by Landsat's deep archive of imagery. In 1987, the terminus of Erasmo Glacier was at the end of a low sloping valley. By 2015 it had retreated almost 3 kilometers, and formed a water body referred to as a proglacial lake. The end of the glacier now lies

Image of the Week: Glacial Retreat Fills Alaska Lake

The visible impact of climate change on the Earth’s surface is often clearest in the Arctic’s receding glaciers and swelling glacial lakes. Southeastern Alaska’s Harlequin Lake is one of the fastest-growing in North America. These false color Landsat images show the rapidly-retreating Yakutat Glacier, which feeds the lake. Landsat can be used to illustrate the lake’s

Global Land Surface Temperature from 2020 as Observed by Terra MODIS

The surface temperature of the land changes rapidly across the world throughout the course of one year. This video shows the changing temperatures throughout 2020 using 8-day land surface temperature (LST) data from the Terra MODIS satellite sensor. For more information on the data used to make this video please visit the LP DAAC website:

Eyes on Earth Episode 44 – Landsat Water Atlas

Dr. Alan Belward has spent a lot of time thinking about the planet’s surface water. The former Landsat Science Team member uses satellite data to track changes to lakes, rivers, and streams, and recently published a book that uses Landsat data to tell some of those stories. In this episode of Eyes on Earth, we hear about some of the surprising things Belward and his team

Image of the Week - 2004 Indian Ocean Tsunami

On December 26th, 2004, a massive 9.1 magnitude earthquake struck off the west coast of northern Sumatra, Indonesia. The third largest earthquake ever recorded lifted the sea floor several meters, causing tsunami waves to ripple out in all directions and race across the ocean. Banda Aceh bore the brunt of the waves just 15 to 20 minutes after the earthquake. Waves in some

Eyes on Earth Episode 43 - U.S.-Canada Water Use

The St. Mary and Milk Rivers cross the U.S. and Canadian border and supply water to both countries. Managing that resource in the interest of both nations is a matter of international collaboration and cooperation, and Landsat data is helping offer objective information on water use. On today’s episode of Eyes on Earth, we hear from Roy Sando of the USGS, who’s working

Image of the Week - Fires Tear Through Former Cane Fields

The waves of sugar cane that once defined the Hawaiian island landscape of Maui, have slowly given way to non-native annual grasses in recent decades. Those grasses have become a fire hazard along the way.

The closure of central Maui's last large cane mill in 2016 opened up some 36,000 acres for new growth. Some of those acres burned in 2019 during one of the island

Eyes on Earth Episode 42 – Rangelands of the U.S.

The extensive rangelands across the Western United States are threatened by invasive grasses, climate change, and altered fire regimes that can disturb the landscape. The largely semi-arid lands are also important for the survival of species that need undisturbed sagebrush ecosystems to thrive. But most satellite-based land cover datasets don’t offer the kind of detail

Eyes on Earth Episode 41 – Albedo

Albedo—the amount of incoming solar radiation reflected into space from the Earth’s surface—is a key measurement for surface temperatures and plant productivity. It also factors into weather forecasting and climate modeling. Landsat Science Team member Dr. Crystal Schaaf works with graduate and postdoctoral students to measure albedo using satellite data from the

Eyes on Earth Episode 40 – Landsat Collection 2

Landsat data is more useful today than at any other point in its nearly 50-year history. The USGS Collections strategy is a major reason why. Landsat Collections align and correct satellite acquisitions from 1972 through the present to make the data easier to work with through time. The USGS has now released Collection 2, an upgrade that improves geometric accuracy,

Image of the Week - Dam Failure in Uzbekistan

The western wall of Uzbekistan's Sardoba Reservoir breached on May 1st, 2020 after a week of heavy rain. Thousands were evacuated as water rushed north into farmland and villages across the central Asian country and into neighboring Kazakhstan. Imagery from Europe's Copernicus Sentinel-2 satellite shows water pooling across a wide area. In the May 4th image 3 days after
