Fascinating application of NASA's free night lights data to detect light emissions linked to potential construction along the US/Mexico border.
Nice one @JackSapoch, and glad to see the DarkLight Viewer was helpful 🤓

Recent border wall construction in southern Arizona is visible not only in daytime satellite imagery, but also at night I made this timelapse w/ NASA Black Marble nighttime lights data, showing light signatures along the border next to Coronado National Forest b/w Jan + Mar 2026

Anyways, this observation originally came onto my radar while playing around with @BenDoBrown's great Darklight Viewer tool in GEE, which makes it easy to explore changes nighttime satellite data.
Definitely worth checking out if you're interested in these methods!

Beyond the physical construction of the wall, artificial lighting is also part of the project’s environmental footprint.
@CenterForBioDiv in particular has published past work on these risks: biologicaldiversity.org/campaigns/bord…

Private satellite imaging companies are restricting access to imagery over Iran, making it difficult to verify destruction caused by U.S./Israeli strikes. I developed a method to detect building damage in open source radar imagery, now peer reviewed:

IRE calls for the immediate release of Estefany Rodríguez, a reporter for Nashville Noticias and Univision 42 Nashville, who was taken into custody while in a marked news vehicle, according to reports.
Detaining journalists for doing their jobs is a direct threat to press freedom and the First Amendment. We stand with Rodríguez and all reporters working to hold power accountable.

The animation centers on a few buildings (implied targets) displayed as point geometry evocative of LiDAR data
The extent to which this is a generated effect vs data derived geometry is unclear, but past work on IDF animations suggests the former

We traced over 30 unique assets to Washington-based 3D creator Ian Hubert, who makes bespoke models created for his sci-fi project Dynamo Dream, available to his Patreon subscribers. Models of parking lots, antennas, + pipes were repurposed as Hamas and Iranian military sites

This investigation was a collaboration with @MotherJones, @nashvillebanner, @NC5, Nashville Noticias, and @psr_memphis

Last May, Tennessee Highway Patrol joined ICE on the streets of Nashville.
We @LHreports + partners mapped the traffic stops and used 1M+ ICE records, dashcam video, and court files to show how supposed routine encounters became deportations.

A @CNN investigation has uncovered horrific details about atrocities in Sudan, exposing ethnically targeted killings at the hands of the Sudanese Armed Forces and its allies. Worth reading in full: edition.cnn.com/interactive/20…

I’m in Kuala Lumpur this week for the Global Investigative Journalism Conference #GIJC2025
If you’re here + want to talk visual investigations, open source methods, remote sensing, etc. def feel free to reach out!
Super happy to meet potential collaborators/fellow practitioners
