Traversing in Surveying – Types and Methods
A traverse is a series of connected lines whose lengths and directions are to be measured and the process of surveying to find such measurements is known as traversing. In general, chains are used to measure length and compass or theodolite are used to measure the direction of traverse lines. The types of traverse and methods of traversing are discussed in this article. Types of Traverse A Traverse may be of two types. Namely, Open Traverse Closed Traverse 1. Open Traverse A traverse is said to be open traverse when the traverse starts at one point and terminates at another point as shown in the figure. Open traverse is also called as unclosed traverse. It is suitable for surveying of roads, coastal lines, etc. Fig 1: Open Traverse 2. Closed Traverse A traverse is said to be closed traverse when the traverse formed a closed circuit as shown in the figure. In this case, both starting and terminating points of the traverse coincide with each other. It is suitable f
