This data set contains 13 L1-calibrated scenes from the Hyperion hyperspectral sensor onboard the Earth Observing 1 (EO-1) mission, provided by NASA. All scenes are 242 bands and cropped to a standardised 256x1024 size, stored as raw 16-bit unsigned integers, in little endian byte order and in band-sequential (BSQ) order. This data was collected over a varied range of locations around the world between 2000 and 2017 and were obtained from the United States Geological Survey (USGS) Earth Explorer data portal https://earthexplorer.usgs.gov. Specific dates and locations of each scene may be identified using the ID code in the scene name. These scenes compose a test set to evaluate compression algorithms for hyperspectral data.
METHODOLOGICAL INFORMATION
-
Description of methods used for collection-generation of data:
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.

Methods for processing the data:
Level 1Gst is terrain corrected and provided in 16-bit radiance values. The data are available in Geographic Tagged Image-File Format (GeoTIFF) and are distributed via download at no charge.
