![]() The “_rX” in the file name is a revision number that allows marking of files that have been processing more than once for some reason (e.g., revised calibration file or subsetting for a specific application). L1 appendage is reserved for the final, fully processed Level 1 output. Level 1 metadata filenames have an extension attached which indicates the intermediate Level 1 process (e.g., after smear correction, echo correction, dark subtraction) from which the file was generated, although the intermediate files themselves are not included on the tape. The. Table 1 defines all Level 1 data products. ![]() The Level 1R data set consists of radiometrically-corrected images (watts/(sr-micron-m 2)x100), formatted as HDF files, and metadata in binary and ASCII formats. The elevation data used for correction consist of the Shuttle Radar Topography Mission (SRTM) "Finished" data set and other elevation data as required. This addition will correct parallax error due to topographic relief and improve the overall band-to-band registration accuracy. The Level 1Gst product will also include terrain correction through use of a digital elevation model (DEM). Level 1Gst: Absolute Geodetic Accuracy Specification UTM (default zone of the scene center coordinates) The data are available in Geographic Tagged Image-File Format (GeoTIFF) and are distributed via download at no charge through either EarthExplorer or USGS Global Visualization Viewer (GloVis). Level 1Gst is terrain corrected and provided in 16-bit radiance values. 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. 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. If the scene fails the Level 1Gst processing level, it will be removed from the archive and will become unavailable. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers ( additional information).Īll Hyperion and Advanced Land Imager (ALI) data in the archive will be attempted to be processed to the Level 1Gst level of correction. The standard scene width is 7.7 kilometers. The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for all bands. Hyperion collects 220 unique spectral channels ranging from 0.357 to 2.576 micrometers with a 10-nm bandwidth. Hyperion Instrument on board the EO-1 spacecraft 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. 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 Earth Observing-1 (EO-1) satellite was launched Novemas a one-year technology demonstration/validation mission. 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. The NMP was an advanced-technology development program created a new generation of technologies and mission concepts into future Earth and space science missions. The EO-1 satellite was launched on Novemwith the NASA's New Millennium Program (NMP). The Earth-Observing One (EO-1) satellite was decommissioned March 2017.
