Tom Loveland, research scientist with the USGS Earth Resources Observation and Science Center, explains how he uses data — both past and present — to help scientists, natural resource managers, and the public better understand how the face of the planet is shifting and what that change means.
In 2013, Landsat 8 began adding high quality, global, moderate-resolution imagery to the more than 40-year archive of Landsat imagery. To assess the potential effects of the availability of Landsat 8 imagery on users and their work, the U.S. Geological Survey (USGS) Land Remote Sensing Program (LRS) initiated a survey of Landsat users. The objectives of the survey were to
Canada has recreated the recent history of its forest disturbance and related recovery using Landsat data; a history that would otherwise not be possible to recreate in a manner that is spatially explicit and at a spatial resolution of relevance for forest management.
Toward the end of April, reprocessing efforts will begin for Landsat 8 OLI/TIRS scenes acquired from January 1 to March 31, along with data acquired during April, to create nominal Level-1 products containing valid TIRS data.
Landsat missions have always been an important component of U.S. foreign policy, as well as science and technology policy. The program’s longstanding network of International Cooperators (ICs), which operate numerous International Ground Stations (IGS) around the world, embodies the United States’ policy of peaceful use of outer space and the worldwide dissemination of civil space technology for public benefit. Thus, the ICs provide an essential dimension to the Landsat mission.
A first of its kind, the WELD data products were designed with the purpose of providing scienctific quality Landat data consistent in both temporal resolution and quality at a continental scale with limited clouds. WELD products are available at no charge.
The latest Landsat Update (Volume 10 Issue 2 2016) is now available from USGS.
USGS and ESA have established an innovative partnership to enable USGS storage and redistribution of Earth observation data acquired by Copernicus program satellites.
As of Feb. 12, 2016, many of the Landsat 8 scenes acquired from October to December 2015 have been reprocessed into nominal Level-1 products containing valid TIRS data and are available for download, and can also be submitted for higher-level Surface Reflectance data processing via the ESPA On-demand interface.
A marriage in the remote forests of China promises to unite two important forces to better inform the health and future of biodiversity. The union is reported in this week’s journal Ecological Indicators by Michigan State University researchers.
Landsat 8 Thermal Infrared Sensor (TIRS) data continue to be collected with the scene select mirror encoder electronics disabled (mode 0). While in this mode, the TIRS line of sight model (LOS) will be regularly updated and modifications are being made to automate revisions to the LOS in the Level-1 Product Generation System (LPGS).
At #AGU15, Amy Hudson, from the University of Maryland College Park, presented a poster about her work to develop a global surface water dynamics map for the years 2000–2014 using data from three Landsat satellites. We spoke with her about this effort.
Alex Gardner, a Research Scientist at NASA’s Jet Propulsion Laboratory, has used 30 years of Landsat data—some 3 million scenes—to measure the velocity of Antarctica’s ice sheet. He spoke with us about the work he is presenting at #AGU15.
Justin Roberts-Pierel from the Joint Center for Earth Systems Technology, uses Landsat 8 to detect landslides in the Himalayas. He provided information about his studies at #AGU15. We talked with him about his work.
Alex Burton-Johnson, Martin Black, and Peter Fretwell from the British Antarctic Survey have used Landsat 8 data to create a new rock outcrop map for Antarctica, which will become part of the Antarctic Digital Database. The team presented their research at #AGU15.
Jennifer Rover, a Geographer with the U.S. Geological Survey, gave a talk on an automated method she developed to assess long-term change to Earth’s surface using Landsat at #AGU15.
On Nov. 1, 2015 the TIRS instrument experienced an anomalous condition related to the instrument’s ability to accurately measure the location of the Scene Select Mirror.
The Charter concept is this: a single phone number is made available to authorized parties providing 24/7 contact to a person who can activate the charter. Once activated, a project manager takes charge. The project manager knows what satellite resources are available, how to task them to collect data, and how to quickly analyze the collected data to create impact maps for first responders. These maps, provided to responders for free, often show where the damage is and where crisis victims are, allowing responders to plan and execute relief support.
Capitalizing on the long Landsat data record and the human brain’s capacity to recognize movement, Frank Paul from the University of Zurich has created glacier animations that enable viewers to witness the complex flow of glaciers.
In a effort to help sustainable development professionals learn more about Earth observation resources that can help with their work, the World Bank Group released an informational website focused on remote sensing.
U.S. Secretary of the Interior Sally Jewell, leading the U.S. delegation to the 2015 Ministerial Summit of the Group on Earth Observations (GEO), today signed an agreement with Mexico serving as a regional milestone for international cooperation in using land-surface satellite images for the benefit of effective land use planning and sustainability.
