@EricFielding Eric Fielding, an earth scientist at JPL, wants to use that capability to detect earthquake motion previously obscured in heavily forested areas such as Indonesia and the Pacific Northwest. “That’s going to be a huge advantage,” he says.

Having used Copernicus and other systems for land mapping, this is so cool and such a leap ahead. I'm excited to see if I can use this for disaster assessment and recovery.

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

I am excited to be mentioned in this post by Wyvern about my usage of their Open Data Program!

www.linkedin.comWe love seeing what the geospatial community builds using Wyvern’s open data, and this deep dive by Alex Rice is a fantastic example. | WyvernWe love seeing what the geospatial community builds using Wyvern’s open data, and this deep dive by Alex Rice is a fantastic example. In Part 1 of his new series, Alex uses Wyvern’s Open Data Program to run exploratory analysis on chlorophyll-a as a proxy for detecting harmful algal blooms (HABs). Using Python notebooks and interactive maps, he walks through how hyperspectral indices like NDWI and NDCI can help isolate water bodies and signal algal activity, utilizing cloud-native, open-source tools at every step.

In order to fully understand how #LightPollution affects our world, we need to know how much of it is in which places. Divergent results from different measurement methods present some tension, but recent research suggests a way forward.

CALL FOR PAPERS

CAA #Danmark <dk.caa-international.org/> seminar 2026 afholdes tirsdag d. 17. marts @ Holstebro Museum i samarbejde med luftfotoarkæologisk Center.

Årets tema ønsker at sætte fokus på "fjerndetektering og ikke-destruktiv arkæologi":

- Hvilken metode og procedure er best-practice?
- Kan vi supplere eller erstatte fremgangsmetoden for at bedrive arkæologi?
- Er fjerndetektering og ikke-destruktiv arkæologi relevant i forbindelse med kapitel 8?

Remember the big results I posted about last week? We've made short videos to explain what #Nachtlichter was about, and what we measured.

Check it out in English: youtu.be/OhNa-d3HcKc
or in German: youtu.be/hZo17_V_klg

Here's the original paper: nature.com/articles/s44284-025

And here's the thread I wrote about it when the paper first came out: fediscience.org/@skyglowberlin

“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 …”
