A linear survey is a method of land surveying that involves measuring and mapping out a specific area in a straight line, typically using a chain or tape measure. This type of survey is commonly used to determine the boundaries and dimensions of a piece of land, as well as to establish the location and layout of roads, railways, and other linear features. Unlike other types of surveys, a linear survey focuses on the linear distance between points, rather than their angular relationships. This precise and systematic approach to surveying allows for accurate and efficient mapping of large areas, making it an essential tool for land development, construction, and infrastructure planning.
