HySpex Imaging Spectroscopy L2 Surface Reflectance Data

Project:

CHEESEHEAD

Summary

Airborne hyperspectral data acquired using HySpex sensors (VNIR-1800 and SWIR-384; HySpex, Skedsmokorset, Norway) for the Chequamegon Heterogeneous Ecosystem Energy-balance Study Enabled by a High-density Extensive Array of Detectors (CHEESEHEAD) Field Project during four periods: 20190626, 20190711/20190713, 20190804/20190806 and 20190830 are contained in this dataset. Images were geo-rectified and atmospherically corrected to produce hyperspectral surface reflectance at ~ 1 m spatial resolution across 400 to 2500 nm with a spectral resolution of 3 nm in the visible and near infrared region and 5 nm in the shortwave infrared region. For more information, please see the HyspexReadme Excel file.
