Headwall Hyperspectral Reflectance LTER Cedar Creek Minnesota Multi-Year 1 mm

PI: John Gamon, Ran Wang


The Headwall Hyperspectral Reflectance data are for the Long-Term Ecological Research (LTER) at Cedar Creek Ecosystem Science Reserve (CCESR), Minnesota (HWHYPCCMN1MM). The reflectance products are at 1 millimeter (mm) spatial resolution in the 400 to 1,000 nanometer spectral range. This dataset can be used to understand the optical diversity-biodiversity relationship and investigate the spatial sensitivity of the relationship at local scales.

A Headwall Series E imaging spectrometer was mounted on a tram system to collect designated plots for the biodiversity (BioDIV) experiment at the LTER Cedar Creek site. The imaging spectrometer, located 3 meters above the ground surface, obtained 1 mm ground pixel size of hyperspectral field image cubes that are among the finest spatial resolution available. The fine-scale images were acquired at a prairie grassland ecosystem during June/July 2014 and July 2015.

Provided in the HWHYPCCMN1MM product are 920 to 924 hyperspectral bands in an Environment for Visualizing Images (ENVI) format.
