Synthetic Aperture Radar can see through clouds at night and track vehicles from space

Synthetic Aperture Radar is fascinating technology. A lot of it is open source but the really high-end stuff is commercial or nation-state territory. It's capable of seeing at night, seeing through clouds, and tracking the subtlest vehicle movements or airplanes. It is an absolute beast at change detection at scale. It can even tell you which bridges are about to collapse and where landslides are about to happen. Because of the beauty of NASA and the ESA, a lot of the data is publicly accessible. If you want to learn more about this technology, it's quite a fun rabbit hole to go down. It just goes to show how far geospatial technology is going and how it's getting breathed with new life thanks to artificial intelligence.
