Abstract: The introduction of short-range electronic distance measurement in 1971 revolutionized surveying. Thousands of surveying and engineering firms across the U.S. today routinely use EDM for measuring distances. Now another major change in surveying practice looms: the use of the electronic theodolite and of the electronic recording of data in the field. The electronic theodolite automatically senses both the vertical and horizontal angle and displays it on a digital readout. And both angles and distance measurements can be fed into the field data collector at the push of the button. The data collector saves much time back in the office: no longer a need to spend hours keyboarding notebooks full of field data into the computer. In a nutshell, the new developments mean: greater speed, both in the field and office; better accuracy; fewer chances for human error.
