🎉 Fantastic news: The Advisory Committee for #EarthObservation has recommended the WIVERN satellite mission 🛰️as the 11th “Earth Explorer” of the European Space Agency! 🙌 We are extremely excited about this, as our #MPI_scientist Cathy Hohenegger was involved in the proposal & is a member of the scientific Mission Advisory Group of WIVERN. 🤞 Now we are waiting for the final decision by the ESA member states in September! 🔗More info: mpimet.mpg.de/en/communication

How that I have your attention 😉 I would like to exploit it for some work stuff. #RemoteSensing #ImageProcessing communities, I have a real quest. We're segmenting shallow underwarter structures in these archival aerial photos (grayscale, single-band) and the segmentation algorithm picks up... the waves on the water surface, not reefs and such. This gives an artefactual vergence (direction) that is not present in the layer we are interested in, i.e. sea floor. This is SVM in eCognition. Don't mention segmentation in ArcGIS (unless you're a powerful wizard, in that case I bow).
We also have a custom ML model but it's not that good either (yet?). How to get rid of them waves?! #geoscience #EarthObservation

“The Canadian Hydrospatial Network (CHN) is a map-based dataset that includes Canada's lakes, rivers, watersheds and other water features and their connections to each other.
It's applications include:
🗺️ serving as a foundation for advanced hydrologic and hydraulic modelling, including for flooding and drought
🗺️ supporting water and watershed management
🗺️ providing essential base data for cartography…”
You can now explore six new regions …”
