Wyvern Open Data

Wyvern's Open Data Program provides free medium resolution (5.30 m) hyperspectral satellite imagery captured from the Dragonette hyperspectral satellite constellation. The dataset features 23 spectral bands ranging from 503nm to 799nm, with a revisit rate of 2 times a day. The initial release contains 25 images covering various land cover features including forests, wildfire events, pivot and row crop fields, coastal bathymetry, open pit mines, solar farms and well sites from across the globe.
