Prototype: Grounding AI and LLMs with Overture's Cross-Theme Knowledge Graph

LLMs are good with text and bad with coordinates, so they guess when asked where things are. Overture is testing whether map geometry itself can become the connective layer across data themes, giving AI a verifiable spatial graph to reason over. ORATOR, a prototype built by Overture member Wherobots, (led by Daniel Smith) generated 700,000 nodes and 1.2 million edges over the San Francisco Bay Area to see if the idea holds. Geometry is the foreign key. If a place sits inside a building, the data already knows they are related. Nobody had to write that link by hand.
