HyTES Level 1 Flight Paths, Facility Instrument Collection

This dataset contains paths of flight lines for the Hyperspectral Thermal Emission Spectrometer (HyTES) instrument from 2013 to 2023. Flight paths are provided in Keyhole Markup Language (KML) format by a single line representing the flight line nadir (2013-2016) or two parallel lines denoting the imagery swath width (2017-2023). 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 NASA's Twin Otter, Earth Resources ER-2, and GulfStream V aircraft and completed its first flights in July 2012. HyTES was designed to provide high spectral and spatial resolution thermal infrared (TIR) data as a precursor for NASA's planned Hyperspectral Infrared Imager (HyspIRI) orbital mission. It is useful for a number of applications, including high-resolution surface temperature and emissivity measurements, point sources of air pollution, and volcano observations. Two companion files listing imagery pixel size and swath width by platform altitude are included.
