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.
Highlights included hands-on tutorials, lively garden chats, and an exclusive look behind the scenes at @DLR & #ohb
Thanks to all who joined, shared, and inspired!

@DrPlanktonguy It's great to see more hyperspectral missions in space! #VTTFinland has also been active in the field of #hyperspectral technology, with the Reaktor Hello World nanosatellite being the first nanosatellite camera capable of hyperspectral imaging in space. And there is more to come. https://kuvaspace.com/reaktor-hello-world-bids-adieu/
Weekend #Plankton #Factoid
Why are plankton ecologists *so excited about the launch of #NASA PACE #satellite? Because: Plankton Aerosol Cloud #ocean Ecosystem. It is a giant step forward for #phytoplankton id because the new Ocean Color Instrument (OCI) is #hyperspectral, meaning it can image ultraviolet to visible & visible to near-infrared at 5nm resolution 
! Big news because previous satellites only saw a few colors. OCI can now identify algae pigments! #Climate

Space Object Identification and Classification from #Hyperspectral Material Analysis: https://arxiv.org/abs/2308.07481 - "a novel data processing pipeline designed to determine the materials present on unknown space objects, and classify accordingly."
arXiv.orgSpace Object Identification and Classification from Hyperspectral Material AnalysisThis paper presents a data processing pipeline designed to extract
information from the hyperspectral signature of unknown space objects. The
methodology proposed in this paper determines the material composition of space
objects from single pixel images. Two techniques are used for material
identification and classification: one based on machine learning and the other
based on a least square match with a library of known spectra. From this
information, a supervised machine learning algorithm is used to classify the
object into one of several categories based on the detection of materials on
the object. The behaviour of the material classification methods is
investigated under non-ideal circumstances, to determine the effect of
weathered materials, and the behaviour when the training library is missing a
material that is present in the object being observed. Finally the paper will
present some preliminary results on the identification and classification of
space objects.
