OpenHistoricalMap (also spelled Open Historical Map and abbreviated OHM) is an online collaborative mapping project developing a historical map of the world using OpenStreetMap technology and processes.[4][5][6] Whereas OpenStreetMap only includes data about the present day and deletes data as it becomes outdated, OpenHistoricalMap welcomes historical data and preserves multiple copies of a feature as it changes over time.[7][8] The OpenStreetMap community views OpenHistoricalMap as an outlet for keeping outdated names out of OpenStreetMap, where they could cause misunderstanding.[9]
