This field work will continue for 3 field hours.To measure the horizontal distance between two points, one surveyor uses an EDM instrument to shoot an energy wave toward a reflector held by the second surveyor. The EDM records the elapsed time between the wave's emission and its return from the reflector.To determine the horizontal distance (D): (i) Read horizontal scale simultaneously when the vertical scales is read and note the reading by means of the same index α 1. (ii) Multiply the stadia intercept by the reading obtained in (i). This will give correction to be subtracted from the distance (100 S) obtained from the stadia intercept.15 ก.พ. 2564 ...
