USGS Land Change Monitoring, Assessment, and Projection releases ‘unprecedented’ reference dataset for United States
The USGS Land Change Monitoring, Assessment and Projection (LCMAP) team has released its reference dataset for the Conterminous U.S. (CONUS), an 25,000-point trove of land cover data that represents the culmination of nearly five years of intensive human labor.
Pixel by Pixel: How the USGS, U.S. Forest Service Checked the Work of a Computerized Landsat Mapping Project
About a year ago, scientist Bruce Pengra sat at his desk with a conundrum.
As part of the team working on the reference dataset for the USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative’s land cover mapping project, Pengra was staring at a single speck of satellite data, a nondescript blotch of color representing a 30-meter plot of ground in Washington state....

Bauer Discusses Peer Review’s Role in Strengthening Remote Sensing Science
Remote sensing is not an especially recognized scientific discipline, at least in comparison to fields like biology, chemistry, or medicine.
Denali, Tallgrass at EROS Launch New Era in High-Performance Computing Capabilities
One of the challenges in prototyping and evaluating research projects related to the U.S. Geological Survey’s (USGS) Land Change Monitoring, Assessment, and Projection (LCMAP) initiative has been what software engineers call “the last mile problem.”
Calibration Test Site Becomes Agricultural Hotspot
The Landsat satellites were designed to detect landscape changes over time. However, sometimes what Landsat needs to see on the Earth’s surface is no change at all.
Geoscience Australia’s Oliver Discusses Use of Landsat during Country’s Historic Fires
Australia’s historic fires, the Black Summer fires, raged from September 2019 into February of 2020, and weren’t fully extinguished until this past March.
From Concept to Reality, USGS Land Change, Monitoring, Assessment and Projection Pushes Boundaries in Service of Science
More than a decade ago, Tom Loveland sat down to sketch out a few thoughts on land change and the Landsat archive.
The archive was and remains rich with history, adding new observations of the entire planet every eight days. But at that point, Landsat-based land change research was about comparing points in time – this year versus five years ago, to 10 years ago, and so on.
Satellite Constellations: Taking a Collective Look at Earth from 705 Kilometers Overhead
Jim Lacasse, the U.S. Geological Survey’s (USGS) Landsat Mission Operations Project Manager out at the Earth Resources Observation and Science (EROS) Center, told the Eyes on Earth podcast crew a fascinating story the other day about satellite constellations
Rising Seas: EROS Brings Valuable Elevation Knowledge to Islands, Coastlines
As sea levels rise around the planet, as storm surges threaten islands and coastal communities, decision makers face a lot of questions about how to protect their citizens and their landscapes.
EROS Scientists Publish Accuracy, Guidance for Global Evapotranspiration Data
Evapotranspiration (ET) presents a difficult problem.
Evaporation from the Earth’s surface and transpiration from the leaves of plants accounts for about 60 percent of the water budget – a budget that has implications for agriculture and food security the world over.
EROS Reaches Out to Kids with Landsat Activities
The Communication & Outreach (C&O) team at the Earth Resources Observation and Science (EROS) Center is working on some quick ways to connect with students who are currently doing school from home.

LANDFIRE Proves Critical to First Nationwide Tool on Wildfire Risk to Communities
Mayors, city councilors and county commissioners have a lot on their minds.
Questions of policing, budgeting, or public health gobble up time and attention week after week, leaving little room for assessing risk of potential dangers like wildfire – especially for the part-time leaders who make up the bulk of the nation’s local officials.
