Definition

In SURVEYING, an object whose horizontal POSITION is determined by OBSERVATIONS from other STATIONS, no OBSERVATIONS being made at the object itself. Where the object is observed from only two stations, the position is termed a no check position as there is no proof that such OBSERVA­TIONS are free from BLUNDERS. Intersection stations are either objects which would be difficult to OCCUPY with an instrument, or SURVEY SIGNALS whose POSITIONS can be determined with sufficient ACCURACY without being occupied. Also called intersected point.
