Landsat Improving Everyday Life

Landsat: Continuing to Improve Everyday LifeLandsat satellites provide decision makers with key information about the world's food, forests, water and how these and other land resources are being used. The Landsat Application Book, Landsat: Continuing to Improve Everyday Life (PDF, 101 Mb), explores a number of important everyday uses of Landsat that benefit us as a society. The launch of the LDCM satellite ensures that Landsat data will continue to enable these applications.

Value of Landsat-Executive Report

Featured ScienceAcross the country, people in many different sectors of the working world use Landsat imagery. But exactly who these users are, how they use the imagery, and the value and benefits derived from the information that the imagery provides were largely unknown-until now...

Forest-cover Loss in Eastern US
Processing coal at a coal mine in southern West Virginia.

Remote-sensing data, statistical sampling, and change-detection methods indicate that contemporary land-use pressures have a significant impact on the extent and condition of forests in the eastern United States, causing a regional-scale decline in forest cover. Across the East from 1973-2000 an important land-cover transition has occurred: from a mode of regional forest-cover gain to one of forest-cover loss caused by timber cutting cycles, urbanization, and other land-use demands.

Eagerly awaiting Landsat 8
OLI Overview

The Earth Imaging Journal recently featured an article about a launch of vital importance to the global Earth observation science community in December 2012. The joint NASA/USGS Landsat Data Continuity Mission (LDCM) was created to investigate and research options for the most feasible solution to follow the Landsat 7 mission. NASA is acquiring the spacecraft to collect and provide data to DOI/USGS. The USGS is responsible for the operations of this mission, along with collecting, archiving, processing, and distributing the data to the U.S. Government and other users. The Landsat Science Team has been established to address the science goals of the mission. NASA and the USGS plan to implement LDCM in a manner that does not preclude a long-term solution for continuity of Landsat-type data. OLI Instrument   Learn more

Tracking Nature's Cycles
Remote Sensing Phenology

Phenology is the study of recurring biological cycles such as plant budding and animal migrations. The earliest known phenological records were compiled by the Chinese approximately 1000 BC. Today, USGS Remote Sensing Phenology scientists use satellites to track seasonal changes in vegetation on regional, continental, and global scales. Remotely sensed phenological data are useful for assessing crop conditions, drought severity, and wildfire risk as well as tracking invasive species, infectious diseases, and insect pests. Because phenological events are sensitive to climate variation, these data also represent a powerful tool for documenting phenological trends over time and detecting the impacts of climate change on ecosystems at multiple scales.

Landsat 7 helps track Antarctica's emperor penguins
Click to view enlarged version of this graphic.
Landsat 7 satellite imagery is used to track Antarctica's emperor penguins. This true-color image, acquired by the Enhanced Thematic Mapper Plus on the Landsat 7 satellite, 12-4-2002, captures brown stains of penquin guano. Researchers at the British Antarctic Survey (BAS), discovered that looking for guano stains is more reliable than looking for actual penguins since the birds' tuxedo colors blend in with the shadows on the ice. By locating penguin droppings, the BAS team identified 38 emperor penguin colonies along the Antarctic coast. Learn more...
Landsat 5 captures Mt. Redoubt
Mt. Redoubt
On March 1, 2009, Landsat 5 acquired a clear image of the Mt. Redoubt region in Alaska. Scientists have been carefully monitoring the area as Mt. Redoubt has experienced volcanic tremors and gas releases in recent months, activities normally associated with possible eruptions. Landsat 5, having completed 25 years of global observations on March 1 provides a useful tool for monitoring global land surface features and changes. Learn More...
Kingston Fossil Plant Flood
Kingston Fossil Plant Flood
At approximately 1:00a.m. on December 22, 2008, an earthen dam holding a containment pond at the Kingston, Tennessee Fossil Plant gave way, releasing over 500 million gallons of ash and sludge. In a brief time downstream areas were flooded, some with as much as six feet of debris. More than 12 homes were affected, a number of them were destroyed or moved off their foundations. No lives were lost though many families were displaced and the Emory River and shorelines were inundated. Landsat 5 data, acquired the morning of the 22nd, illustrate the effects of the break. The light blue tones in the water bodies indicate sediment flow from the flooding. Clear water in the region has a darker blue tone. Recovery agencies will use the Landsat data and other sources of information on the area to study the extent of the damage and the long term effects of the dam break.

Cyclone Nargis — 2008
Cyclone Nargis
Landsat satellite imagery, acquired shortly before and after Cyclone Nargis hit the coastal region of Myanamr on May 3, 2008, illustrate the flooding and destruction caused by the cyclone. The delta region, which is home to one fourth of Myanmar's 57 million people, is a major agricultural area and its lowlands make it especially susceptible to flooding. The cyclone created a 3.6 meter storm surge which devastated the area. At least 22,000 deaths have been reported, with 41,000 listed as missing. Over 1 million are homeless. Learn More.

Landsat Image Mosaic of Antarctica
LIMA brings the coldest continent on Earth alive in greater detail than ever before through this virtually cloudless, seamless, and high resolution satellite view of Antarctica. The U.S. Geological Survey (USGS), the British Antarctic Survey (BAS), and the National Aeronautics and Space Administration (NASA), with funding from the National Science Foundation (NSF), created LIMA from more than 1,000 Landsat ETM+ scenes.

Georgia Fires
Georgia Fires
Satellite remote sensing research and applications are essential for providing required data for mapping fire fuels, assessing fire effects, monitoring fire danger, and measuring progress in implementing the National Fire Plan. Land management agencies, scientific communities, and citizenry affected by wildland fires can benefit from research and development of consistent and accurate geospatial fire data, maps, and assessment produced at various scales.

South California wildfire
Satellite images of Southern California wildfire and link to larger view
The nearly 11,000 acres affected by the Sierra fire in Orange County, California are seen in these Landsat 5 images. The image on the left was acquired three days prior to the breakout of the fire. The image on the right was acquired the day the fire was contained. The burned areas show as the deep red tones in the center of the right image.
