Linear distance measurement is the process of determining the length of a line. In civil engineering, this is a fundamental skill that is used in a variety of applications, such as site layout, construction staking, and topographic mapping. There are a number of different methods for measuring linear distances, each with its own advantages and disadvantages. The most common methods are: Chain surveying: This method uses a chain, which is a length of metal or wood that is marked off in units of feet or meters. The chain is stretched between two points, and the distance between the points is determined by counting the number of links in the chain. Tape surveying: This method uses a tape measure, which is a flexible measuring device that is marked off in units of feet or meters. The tape measure is stretched between two points, and the distance between the points is determined by reading the measurement on the tape measure. Total station: A total station is an electronic surveying i...
