In its NGS Documentation File, the NGS says that the to-reach part of datasheets begins with a well-known location that will remain through time, such as the junction of state, federal or interstate highways. Legs along the the route are given as right or left turn, compass direction followed, road name if any, distance traveled in kilometers (miles), and leg terminating feature. The to-reach ends with the phrase, "TO THE STATION ON THE RIGHT/LEFT."

The paragraph following the to-reach section first details the survey mark that is observed, then the monument in which the mark is set, then ties are given FROM features in the vicinity of the station TO the station, with horizontal distances reported to the closest 0.1 m (0.1 ft).
