How Google processed post‑Katrina imagery

2025 marks 20 years of Google Maps — a tool that many of us would be, quite literally, lost without.

We hear from New Orleanians who used Google Maps/Google Earth in its inaugural year to survey the damage to their homes following Hurricane Katrina.

We also talk to the internet's Map Men, who ask whether "the best maps humanity has ever produced are simultaneously the worst maps for humanity?" in their new book, "This Way Up: When Maps Go Wrong (And Why It Matters)."
