Revealing #palimpest with #multispectral #imaging! These amazing results, showing a #Merovingian overtext and a 5th-century Gospel undertext, were achieved by my colleague Alex Zawacki at Göttingen. I'll be presenting the full results of this and other cool discoveries in May at a German-language conference in Kiel.

Identification of native vegetation species by linking UAV imagery with terrestrial spectroradiometers
https://iapetus2.ac.uk/studentships/identification-of-native-vegetation-species-by-linking-uav-imagery-with-terrestrial-spectroradiometers/
This project will develop accurate and efficient spatial data science methods to classify and monitor native vegetation species in subtropical regions from #UAV #multispectral #imagery and field #spectrometer data.

The authors here employ multi-spectral satellite data to create a methane detection tool with global coverage and high temporal and spatial resolution.
Zum Ende meines Bibliotheksreferendariats habe ich vier Wochen lang das Handschriftenzentrum an der @ubleipzig kennengelernt. Inklusive war die Teilnahme am „9. Alfried Krupp-Sommerkurs für Handschriftenkultur“, in dem auch #multispectral #imaging zum Einsatz kam. Danke an das tolle Team für eine schöne Zeit 
Teaching on #multispectral #imaging - lots of new terminology to share today! #palaeography
Seit heute online: meine Antwort auf die ABI Technik-Frage: Wofür wird multispektrale Bildgebung in wissenschaftlichen Bibliotheken eingesetzt? https://doi.org/10.1515/abitech-2024-0020 #multispectral

@ubleipzig @hsprtl @bibverband @unileipzig „Immer häufiger spielen Verfahren der digitalen Fotografie (samt Multispektraltechnik), der Text- bzw. Schrifterkennung und künftig sicherlich auch naturwissenschaftliche Methoden eine Rolle.“ | Wichtige Aussage und sehr zutreffend.

I should also say that @InsularMSS will involve not only #medieval #manuscript studies but also #digitalhumanities and scientific research: palaeoproteomics, #multispectral and photometric stereo #imaging, handwritten text recognition (#HTR), Raman and XRF #spectroscopy, infra-red #microscopy & much more. Perhaps most important, though, will be the freedom and time to do this important work!

“With a trio of smaller satellites that can each detect 26 wavelengths of light, the Landsat Next mission is expected to look very different from its predecessors that have been observing Earth for 50 years. This new plan for Landsat Next, a joint mission of NASA and the U.S. Geological Survey, is designed to provide more frequent, and finer resolution, data of the changing surface of Earth…”

@litteracarolina @medievodons @histodons @historikerinnen It's great that you also teach the processing of #multispectral data. Hoku is really an important tool for the future of visualising lost writing and other features.
Today my students and I are on our way to beautiful #Vercelli and #Verona for our annual week-long spring school! We’re working with some amazing #medieval #manuscripts there (including the Vercelli Book!), but also with modern technologies like #multispectral imaging and endoscopy. I’ll try to post images of some of our activities using #Vercelli2024. But first - 11 hours on the train…

Sometimes, #bugs lead to pretty funny results. In this case, I was processing this #calibration data for our #multispectral #camera again and apparently, I effed up my memory management, which lead to memory corruption and ultimately this funny picture of me. Unfortunately, I was unable to reproduce the bug, so, I guess it'll live on as a funny edge case in my program :)
