NASA's Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) released a new Surface Biology and Geology (SBG) High Frequency Time Series (SHIFT) dataset.
This dataset contains Level 1A (L1A) unrectified surface radiance image files as well as files of observational geometry and illumination parameters and supporting sensor band information from NASA's Airborne Visible InfraRed Imaging Spectrometer - Next Generation (AVIRIS-NG) instrument.
In this dataset, for each flight line, four file types are included: unrectified measured surface radiance image (rdn) files, geometric lookup table (glt), gridded files of input geometry (igm), and parameters relating to the geometry of observation and illumination rendered using the geometric lookup table (obs). The AVIRIS-NG data are provided in ENVI binary format, which includes a flat binary file (bin) accompanied by a header (hdr) file holding metadata in text format.
