ABSTRACT
The optical plumbing is a basic geodetic method. Special instrument (optical plummet) is used. The optical plummets are equipped with a telescope with peephole looking both up and down or only up. In these days there are many different works for many different instruments, but most surveying companies only want one universal instrument. Some total stations can be set to the vertical direction (zenith) with using a special angled eyepiece. The article is focused on the use of a total station for optical plumbing. Two methods of optical plumbing were used. The first method is based on the deduction of the vertical position from special target. The second is based on polar method, where the center of the target is surveying. The results from the total station are compared with the optical plummet which is equipped with a special measuring table for precise engineering measurement.
