What a terrible article, no explanation of why MethaneSat went quiet, likely power loss. Time to build a constellation of these. Methane reduction is easy wins.

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

Question for #ecology and #remotesensing folks:

Can GEDI AGBD values be averaged within an AOI to produce an estimate? All the information I'm seeing suggests creating a model with additional products. Is that just to get estimates with better resolutions or for time periods before GEDI availability, or is there some other reason I'm missing?

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.

“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 …”

Reminder: my #LPS25 talk is tomorrow - literally the last talk of the conference.

But I promise it's going to be entertaining and you'll leave on a high note! Here's a sneak peak...

[I spent a lot of time living, working and exploring in the PNW – ski bum in Whistler, many dives, offroad motorcycling, engineering geologist, spatial data, cultural + technical + history reading, otherwise exploring, etc – and am fascinated by this area personally and professionally…]

At #LPS25 the #Sentinel2 team just said that they will support nighttime observations in Sentinel 2NG.

My understanding was that this was expected to be impossible with the existing architecture, so I'm very curious to hear more!
