Theodolite traversing: distances are obtained using measuring tapes and EDM’s and directions are deduced in the horizontal angles calculated by a theodolite
30 yrs ago, GPS engineering was released for the survey planet—but only for individuals who could shell out tens of thousands of dollars. Electronics in nearly every other sector have grown to be more and more cost-effective.
The multiplication process is accustomed to evaluate traverse angles that has a much better diploma of precision than which can be realized with a little level of vernier embedded inside the theodolite. In this technique, the angle actions three or 4 situations by Keeping the vernier clamp when it sees the rear station.
