The Historical Marker Database (HMdb.org) is an online database that documents locations of numerous historical markers in the United States as well as other countries. The database was launched in 2006 by computer programmer J. J. Prats. The HMdb served as the basis for the database for the online augmented reality game Ingress, which was then later repurposed for Pokémon Go. The HMdb displays historical event locations using Google Maps.
