Geospat: experiments in verifying the physical world
Synthos grades what experts say and what markets price. Geospat is the third lane: what the ground shows. Open experiments in geospatial data quality, entity matching, and change detection — built on Overture Maps open data, with methods and accuracy published like everything else we do.
The Ann Arbor GERS Crosswalk in progress
Matching public registries — food-service licenses, liquor licenses, rental registrations, SNAP retailers, bank branches — to Overture Maps GERS entities for one well-known, fast-changing college town. Deliverables: the open crosswalk table, a precision/recall study with a published failure-case gallery, an independent Overture Places coverage audit, and a GERS ID stability report across releases. Every match graded; every miss explained.
Nothing here is investment advice; Geospat pages are research engineering, not securities research.
