Background

The distance measurement refers to the work of measuring the length of a connecting line between two points on the ground. What is usually measured is the horizontal distance, i.e. the length of the two-point connection projected on a level surface. It is one of the elements that determines the planar position of ground points. Is one of the most basic tasks in the measurement work. What is usually measured is the horizontal distance, i.e. the length of the two-point connection projected on a level surface.

Distance measurement is required in triangulation, wire measurement, topographical measurement, engineering measurement and other tasks. The accuracy of the distance measurement is expressed in terms of relative error (relative accuracy). I.e. the ratio of the error of the distance measurement to the length of the distance, is expressed in equation 1/n with the numerator 1. The smaller the ratio, the higher the accuracy of the distance measurement. The distance measurement method commonly used includes measuring scale and distance, measuring sight distance, measuring distance by a parallax method, measuring distance by electromagnetic waves and the like.
