Traversing is a method used in surveying to establish control networks). It involves placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point). Traverse lines are measured for length using chains, and their direction is measured using a theodolite or compass. The types of traverse are open traverse and closed traverse. In open traverse, the lines form a circuit that ends elsewhere except the starting point, while in closed traverse, the lines form a circuit that ends at the starting point. The methods of traversing are chain traversing, compass traversing, theodolite traversing, and plane table traversing. Each method is categorized based on the survey instrument used. Traversing has many advantages, including less reconnaissance and organization needed, the ability to change to any shape and accommodate different terrains, and only a few observations need to be taken at each station).
