'The Earth Observing-1(EO-1) satellite was launched on November 21, 2000 by the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) as a one-year technology demonstration mission to evaluate the performance of advanced capabilities for future space missions. The EO-1 mission validated highly integrated multispectral data from the Advanced Land Imager (ALI) sensor and hyperspectral imaging data from the Hyperion sensor. After the initial technology mission was accomplished, NASA and the USGS agreed to continue the EO-1 program due to high interest in the specialized data from scientific communities. EO-1 Data products consist of imagery collected during the original one-year mission, as well as more recent Data Acquisition Requests (DARs) from the EO-1 Extended Mission. EO-1 scenes are processed to Level 1Gst (L1Gst) and images with adequate ground control points are processed to Level 1T (L1T). L1Gst and L1T products are provided in GeoTIFF format. Scenes that have been processed to L1T are also available as Full Resolution Browse and GIS Ready Bundle products in JPEG format. Level 1R (L1R) products in HDF format are only available for Hyperion data.'

The Earth-Observing One (EO-1) satellite was decommissioned March 2017. The EO-1 satellite was launched on November 21, 2000 with the NASA's New Millennium Program (NMP). The NMP was an advanced-technology development program created a new generation of technologies and mission concepts into future Earth and space science missions. Information of the EO-1 mission can be found on the EOPortal. All EO-1 ALI and Hyperion historical data will continue to be available through EarthExplorer for the foreseeable future. EO-1 Product Description The Earth Observing-1 (EO-1) satellite was launched November 21, 2000 as a one-year technology demonstration/validation mission. After the initial technology mission was completed, NASA and the USGS agreed to the continuation of the EO-1 program as an Extended Mission. The EO-1 Extended Mission is chartered to collect and distribute Hyperion hyperspectral and Advanced Land Imager (ALI) multispectral products according to customer tasking requests. Hyperion Instrument on board the EO-1 spacecraft Hyperion collects 220 unique spectral channels ranging from 0.357 to 2.576 micrometers with a 10-nm bandwidth. The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for all bands. The standard scene width is 7.7 kilometers. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers (additional information). All Hyperion and Advanced Land Imager (ALI) data in the archive will be attempted to be processed to the Level 1Gst level of correction. If the scene fails the Level 1Gst processing level, it will be removed from the archive and will become unavailable. As of June 15th, 2009, not all of the EO-1 data has been processed; please continue to check back if the scene of your interest is not available. We will be making attempts to process the failed scene as time and workload permits; however there are no guarantees that all of the EO-1 scenes will be able to be processed.

Earth Observing-1 (EO-1) is an advanced land-imaging mission that will demonstrate new instruments and spacecraft systems.

Advanced Land Imager (ALI) provides image data from ten spectral bands (band designations). The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for the multispectral bands and 10 meters for the panchromatic band. The standard scene width is 37 kilometers. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers (additional information). For Advanced Land Imager (ALI) data, the following levels of correction are available: Level 1R radiometrically corrected with no geometric correction applied. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) and are distributed on CD-ROM, DVD, and File Transfer Protocol (FTP). Level 1Gs is geometrically corrected and will be provided as a single "stitched" file. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) or Geographic Tagged Image-File Format (GeoTIFF) and are distributed on DVD and File Transfer Protocol (FTP). Level 1Gst is terrain corrected and will be provided as a single "stitched" file. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) or Geographic Tagged Image-File Format (GeoTIFF) and are distributed on DVD and File Transfer Protocol (FTP). [Source: USGS/EDC Homepage]

The Earth Surface Mineral Dust Source Investigation (EMIT) instrument measures surface mineralogy, targeting the Earth’s arid dust source regions. EMIT is installed on the International Space Station (ISS). During its one-year mission, EMIT will take mineralogical measurements of the sunlit regions of interest between 52° N latitude and 52° S latitude. A map of the regions being investigated can be found on the EMIT website. The EMIT Level 1B Corrected Spacecraft Attitude and Ephemeris (EMITL1BATT) Version 1 data product provides both corrected and uncorrected attitude quaternions and spacecraft ephemeris data obtained from the ISS, including Earth-centered inertial (ECI) position and velocity, and associated time elements. The data are provided in 1 second intervals, and each product file contains vectors from the duration of the orbit. The time elements are copied from the ISS raw data. The data for each EMITL1BATT granule are delivered in a single Network Common Data Format 4 (netCDF-4) file.

The USGS Earth Resources Observation and Science (EROS) Center archive holds data collected by the Landsat suite of satellites, beginning with Landsat 1 in 1972. All Landsat data held in the USGS EROS archive are available for download at no charge.

The Earth Observation Assessment (EOA) is a Congressionally-directed periodic evaluation of the nation's civil Earth observation portfolio. This portfolio comprises both remote and in-situ sensors, operated by both the public and the private sector. The Earth Observation Assessment measures the effectiveness of the civil Earth observation system in meeting federal government objectives identified as Societal Benefit Areas (SBA). The White House Office of Science and Technology Policy (OSTP) charters the U.S. Group on Earth Observations (USGEO) as a subcommittee of the National Science and Technology Council (NSTC) Committee on Environment. USGEO conducts the Earth Observation Assessment to inform the regularly-updated National Plan for Civil Earth Observations, which serves to coordinate the development and support of the Earth observation enterprise across all sectors. This is the data that supports the EOA 2023 Tableau Dashboard on the USGEO website.
