The Civil Engineers Forum explains that surveyors measure distances by stretching tape, chains, strings or similar objects between two points. Learning Outcomes for RHS Level 2 R2111 (Understanding Garden Features, Plant Selection and Planning) : ''Describe how to carry out a basic linear survey including the use of tapes, offsets and triangulation.'' In this instance (at level 2) the terms triangulation and trilateration are synonymous. The number of revolutions registered by the odometer can then be multiplied by the circumference of the wheel to get the distance. Control points: - triangulation of traversing. Optical measurement methods: It is done with a Tacheometer, which works on the principle of optics. Linear surveying is a series of three techniques for measuring the distance between two or more locations. It involves using survey equipment to measure the distance between two points on the Earth's surface, which can be accomplished in different ways (depending on the level of accuracy required). Land survey (a) Topographical survey Horizontal and vertical locations of points by linear and angular measurements to plot natural and man made features.
