Making a TRAVERSE A TRAVERSE is survey work in which distances and angles are connected. A loop consists of several consecutive straight lines and at the end of each side of the lines there is a loop pin, which can be permanent or temporary, depending on the application. The exit point must be a pair of evidence pins or a pin with a coordinate value and a reference pin. The circumference pins are called horizontal control pins. The distance between the circumference pins must be surveyed with a round-trip steel tape or surveyed with electronic tools (Electronic Distance Measurement = EDM). In making the circumference, it is done to Surveying for engineering design and construction Make map markers for land ownership surveys. Make road markers for surveying and mapping the terrain. Used to create ground control points for mapping. The loop is divided into 2 types: closed loop (CLOSED TRAVERSE) and open loop (OPEN TRAVERSE).
