Geolocating a random island using geometry and CUDA programming

A researcher solved a geolocation challenge by analyzing a drone photo of a tropical island resort using geometric analysis and CUDA programming rather than reverse image search. They extracted the relative positions and angles of three visible landmasses to create a "fingerprint," then systematically searched a global coastline dataset (OpenStreetMap) using heuristic filters based on tropical latitude, local density, and clustering to identify the island's location.
