A lidar point cloud along central California’s Big Sur coast displaying elevation, classification, return number, and intensity. The airborne lidar point cloud was collected in 2022 has a point density of 85 points/m2.
Ever wondered what #lidar point clouds reveal about forests? OpenForest4D’s new guide breaks down how elevation, return number, intensity, and classification describe forest structure.

NIH, NASA, NSF budget cuts, FY 2026 - catastrophic. https://joshuasweitz.substack.com/p/the-white-house-vision-for-dismantling
The White House Vision for Dismantling Science in One Simple Plot
(Proposed NIH, NSF, and NASA budgets would be catastrophic for innovation and discovery. But they aren’t reality yet. The time to speak up is now.)

Effective immediately, the PGC is no longer accepting new NSF-supported requests due to a lack of renewal funding. Current work is wrapping up. Please contact your NSF program officer if impacted. We’re grateful to have supported your polar research. Read our full statement at www.pgc.umn.edu

Incompetence in Washington puts every American at risk, no matter how you voted. No one should be happy that the DOGE team - the same folks who randomly published classified U.S. security information online today - wants access to your bank account & Social Security numbers.
