@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

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

Screenshot from Youtube with the title slide of the presentation. A person is holding an app and looking at a light. There is a title text that says "Nachtlichter project", logos from the BMBF, Helmholtz Association, RUB, GFZ, and the Nachtlichter logo, and a small cutout showing me giving the talk.

Over 100 Chachapoya structures discovered at Gran Pajatén in Peru’s Andes Archaeologists have uncovered over 100 previously unknown structures at Gran Pajatén, a centuries-old archaeological complex in Peru’s Río Abiseo National Park. The discovery fundamentally reinterprets the site, one of the most iconic remnants of the Chachapoya civilization—an ancient Andean culture known as the “people of the cloud forest.” Aerial and terrestrial LiDAR scanning, photogrammetry, topographic mapping, and technomorphological analysis were used by the researchers to map the dense terrain without damaging the fragile ecosystem or the remains beneath the forest canopy. The discovery is a follow-up to previous work done by researchers in the 1980s that only documented 26 buildings. The findings reveal that Gran Pajatén was not a remote ceremonial outpost, but rather a central node in an articulated territorial system...
