Electronic distance measurement (EDM) is a method of determining the length between two points, using phase changes, that occur as electromagnetic energy waves travels from one end of the line to the other end.
Electronic distance measurement (EDM) is a way of determining the length between two points by looking a phase changes that occur as electronic energy waves, which travel from one end of a straight line to the other.
Electronic Distance Measurement (EDM) is a remarkable technology used in surveying to measure distances with extraordinary accuracy. At its core, EDM measures the time it takes for a signal to travel from the instrument to a target and back.

The basic working principle of an electro-optical distance meter is explained with reference to the type of instrument which uses an analogue phase measuring system. Such instruments display the functions of the different components more clearly. The light-source produces the so-called carrier wave. The wave is described by
The basic principle is to project a signal (a pulse of some shape) onto the target and process the reflected signal to determine the distance of the target. We have taken the time of flight approach, wherein the delay between transmitted and received pulses (or the time of flight of the projected ultrasonic pulses) is measured to get the distance.

Electronic measurement is a modern method of precise and rapid determination of slope (line-of-sight) distances. Some electronic distance-measuring instruments (EDMIs) are designed to reduce the slope distances to hori zontal distances. Electronic Distance Measurement (EDM) - KSU Faculty ...
Electronic Distance Measurement. J. M. Rüeger. 352 Accesses. Abstract. EDM instruments are classified according to the type of carrier wave employed. Instruments using light or IR waves are classified as electro-optical instruments. Instruments based on radio waves are generally called microwave instruments.
Electronic distance measurement (EDM) is a revolutionary technology that has transformed surveying and other distance measurement tasks. It replaces traditional methods like chains, tapes, and even laser rangefinders with a much faster, more accurate, and longer-range approach.
