EDM (Electromagnetic Distance Measurement)

Electromagnetic Distance Measurement (EDM) is a technology used to measure distances accurately using electromagnetic waves, typically lasers or microwaves. In this process, a device sends a signal to a target and measures the time it takes for the signal to bounce back. By calculating the time and knowing the speed of light, the distance can be precisely determined. EDM is commonly used in surveying, construction, and geodesy, helping professionals create accurate maps and layouts. This method offers advantages over traditional methods due to its speed and precision.
