This dataset contains Level 1 (L1) per-pixel geolocation information from the Hyperspectral Thermal Emission Spectrometer (HyTES) instrument. This is the NASA Earth Observing System Data and Information System (EOSDIS) facility instrument archive of these data. The NASA HyTES is an airborne imaging spectrometer with 256 spectral channels between 7.5 and 12 micrometers in the thermal infrared part of the electromagnetic spectrum and 512 pixels cross-track. HyTES has been deployed on DHC-6 Twin Otter, NASA's ER-2, and GulfStream V aircraft and completed its first flights in July 2012. Geolocation information includes latitude, longitude, height, and ray path length (m). This Facility Instrument dataset includes the L1 geolocation files from the HyTES flights in years 2013 to 2016. The data are provided in comma-separated values (CSV) format.
