Originally named the National Congress on Surveying and Mapping when it was founded in June 1941, the society sought to better coordinate the nation’s surveying and mapping activities. Later the name was changed to the American Congress on Surveying and Mapping to encompass members from Canada and South America. Today, although the majority continue to come from the United States, the members of ACSMs Member Organizations include more than 7,000 surveyors, cartographers, geodesists, and other spatial data information professionals working in both public and private sectors throughout the world.
