That’s a wrap! The 2nd EnMAP User Workshop brought 3 packed days of talks, posters & hands-on tutorials —exploring how EnMAP data supports research on vegetation, water, soil & atmosphere.

These spectra illustrate how individual light sources can be identified and compared. The highest spectral peak in the brightest pixel of this hyperspectral image is approximately 50,000 times higher than the peak in the darkest pixel. The full dynamic range (highest peak to lowest trough) is considerably greater and can be maximised further with longer exposure times to reduce noise](https://media.astrodon.social/media_attachments/files/113/799/383/472/048/588/original/910393efa1a84360.png "Example hyperspectral scan of Falmouth (UK) docks at night. a Panoramic photograph of the scene taken with a Huawei P30. b HOSI’s hyperspectral RGB preview image. c Radiance plots created by the HOSI GUI at chosen pixels (x-axis: wavelength [nm]; y-axis: linear radiance Le [W.sr−1.m−2.nm−1]).

! Big news because previous satellites only saw a few colors. OCI can now identify algae pigments!
