An official website of the United States government. On projects that don't require survey control, localized control may . control, horizontal-1 Physical stations which have known horizontal coordinates (longitude and latitude), and which can be used to provide horizontal coordinates for other surveys. If an elevation is marked on a map, but there is no physical mark on the ground, it is a spot height. survey control marks can be achieved by including the survey within NGRS adjustments (State, Territory and Australian Government).
