Également dans @mariannelemag.bsky.social (le "print"), le portrait d'un chercheur suisse qui marie sols, eau, neige et satellite pour faire de la prévision de catastrophes, et ne baisse pas les bras. Il est toujours plein d'espoir, @greggiuliani.bsky.social.
#ImageOfTheMonth #SwissDataCube | Using #Sentinel-2 and other #Environmental descriptors from #swisstopo we are able to produce a consistent 10m #LandCover map of the entire #Switzerland. This will enable tracking changes in a very detailed way. #EO4impact
