A Traverse is a series of a connected lines whose length and direction are measure in the field. The fieldwork in a theodolite traverse consists of the following: (i) reconnaissance, (ii) selection and marking of stations, (ii) measurement of traverse lines, (iv) angular measurements and (v) picking up the details. Types of Traverse In Open Traverse , the endpoint is not the same as the starting point, the traverse starts at a point P and goes along a direction that does not return to the point P. Fig 1: Open Traverse In Closed Traverse , the traverse ends at the starting point forming a closed loop. Fig 2: Closed Traverse In the figure above, the stations P, Q, R, and S of a traverse are called traverse stations, and the lines PQ, QR, and RS are called traverse lines. The direction of the traverse has shown with an arrow. General Procedure of Theodolite Traverse 1. Set up the instrument over the station P. Centre and level it accurately. Keep the telescope in the normal positio
