HORIZONTAL DISTANCE MEASUREMENT. 1  In plane surveying, the distance between two points means the horizontal distance. If the points are at different elevations, then the distance is the horizontal length between plumb lines at the points. 2  Pacing -- accuracy 1 / 100. Tacheometry (stadia) -- accuracy 1 / 1000.
