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

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

USGS End of Year Accomplishments 2020

A 2020 year in review of the many accomplishments of the US Geological Survey. A year that began with seismic activity in Southwest Puerto Rico, to the first-ever public testing of USGS ShakeAlerts, USGS scientists and technicians helped to track storm data during the 2020 Atlantic Hurricane season. Mapping in high resolution the Nation's rivers and streams, to precise

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

Productivity of Black Oystercatchers in Southwest Alaska

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species. To address these issues, the goal of this research is to

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,

La encrucijada del fuego silvestre

La relación entre la gente y los incendios forestales siempre ha sido paradójica: el fuego es esencial como proceso ecológico y herramienta de gestión, pero también puede ser perjudicial para la vida y la propiedad. En consecuencia, los regímenes de incendios se han modificado a lo largo de la historia, mediante quemas intencionales para promover sus beneficios o mediante

Wildfire at the Crossroads

The relationship between people and wildfire has always been paradoxical: fire is an essential ecological process and management tool but can also be detrimental to life and property. Consequently, fire regimes have been modified throughout history through both intentional burning to promote benefits and active suppression to reduce risks. Reintroducing fire and its

Using Landsat and Machine Learning to Map Urban Change

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
