The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth, launched by NASA and USGS since 1972. Learn about the history, satellite chronology, spatial and spectral resolution, and uses of Landsat imagery for various fields of research and applications.
A comprehensive list of Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the Earth. The list covers both public domain and private domain satellites, with name, status, agency, launch date, and description.
SRTM is a NASA project that obtained digital elevation models of Earth using radar on board the Space Shuttle Endeavour in 2000. The data are available in different versions, resolutions and formats, and can be used for geographic information systems and hydrological applications.
Landsat 3 is the third satellite of the Landsat program. It was launched on March 5, 1978, with the primary goal of providing a global archive of satellite imagery. Unlike later Landsat satellites, Landsat 3 was managed solely by NASA. Landsat 3 decommissioned on September 7, 1983, beyond its design life of one year. [2]
Landsat 9 is an Earth observation satellite launched in 2021 with near-identical instruments to Landsat 8: OLI-2 and TIRS-2. OLI-2 collects data for nine spectral bands with a ground sample distance of 30 m for all bands except the panchromatic band.
EROS is a USGS facility in South Dakota that manages and distributes satellite and aircraft data of the Earth's land surface. It also conducts research and systems development for Earth resources observation and science.
After the success of TIROS-1 and ATS-3, NASA in conjunction with United States Geological Survey (USGS), progressed forward in Earth observation through a series of Landsat satellites launched throughout the 1970s and 1980s.
Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...
