The USGS SRTM data is based on NASA's SIR-C instrument. It is available in at the following versions: Version 1 (2003–2004) is almost the raw data. [7] Version 2.1 (~2005) is an edited version of v1. Artifacts are removed, but voids are not yet filled. There are 1-arcsecond data over the US. [8]
One year after launch, Landsat 8 imagery had over one million file downloads by data users. Landsat data provides information that allows scientists to predict the distribution of species, as well as detecting both naturally occurring and human-generated changes over a greater scale than traditional data from field work.
The Center for Earth Resources Observation and Science (EROS) is a United States Geological Survey data management, systems development, and research field center It serves as the national archive of remotely sensed images of the Earth's land surface acquired by civilian satellites and aircraft.
Currently, the data collected by the satellites in EOS is digitised and collated by the Earth Observing System Data and Information System. Scientists then use this data to predict weather events, and more recently to predict the effects of climate change for treaties such as Paris Climate agreements, with data mainly being collected by EOS and ...
The National Environmental Satellite, Data, and Information Service (NESDIS) was created by the National Oceanic and Atmospheric Administration (NOAA) to operate and manage the United States environmental satellite programs, and manage the data gathered by the National Weather Service and other government agencies and departments.

[2] The National Map is part of the USGS National Geospatial Program. [3] The geographic information available includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures and land cover. The National Map is accessible via the Web, as products and services, and as downloadable data ...
Landsat 5 significantly exceeded its designed life expectancy, lasting several decades beyond its original three-year mission. Contributing to Landsat 5's longevity was the presence of extra fuel for possible future retrieval by the Space Shuttle. [11] If the need arose, Landsat 5 could use the extra fuel to move into a lower orbit.
The Libre Map Project was started by Jared Benedict and around 100 additional individuals contributing money to purchase (or "liberate") a full set of 1:24K scale USGS topographic maps in Digital raster graphic form. [1] The map files were then hosted by archive.org to ensure the map data will continue to be freely available to everyone ...
