Pdf balancing the closed traverse in land surveying. Aait, department of civil engineering 2 lecture note. When a series of connected lines form a closed circuit, i. In surveying, propagation involves obtaining information about a function or process, or computation involving variables. It is not possible to check the consistence of angles and distance measurement. Breeze through control, boundary, site, topographic, cadastral and mortgage surveys, construction staking, subdivision design, road layout, plat checks, area computations. Selection of traverse definition a traverse is a series of straight lines called traverse legs.
It starts at a point of known position and terminates at a point of unknown position. The purpose of a traverse surveys is to control subsequent detail, i. In this explanation we will only be concerned with traverses in. Balancing the latitudes and departures of a traverse. Traverse surveying traverse is a method in the field of surveying to establish control networks. Basic surveying theory and practice for performing certain mathematical operations with angles, it is sometimes easier to convert to decimal degrees first, perform the necessary math, then convert back to degrees, minutes, and seconds. Traverse networks involved placing the survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. To download traverse working xls file click on this link s. Civl 1112 surveying traverse calculations 1 surveying traverse. Areas of all triangles and trapeziums are calculated and added together to calculate the total area of open field closed traverse as. Least squares is an adjustment technique founded on wellaccepted principles of measurements and their errors and is regarded as superior to all other methods of adjustment.
The interior angles of a closed traverse should total. To know more about traverse correction procedure, click the link below. These are illustrated in figures 5a and 5b respectively. Pdf traversing is a fundamental operation in surveying and the assessment of the quality of a. D egreesminutesseconds d ecimal degrees 1 0 2 3 12 1 8 1 1 4 2. A traverse is developed by measuring the distance and angles between points that found the boundary of a site we will learn several different techniques to compute the. When a sequence of connected lines extends along a general direction and does not return to the starting point, it is known as open traverse or unclosed traverse. Unlike cad and other software traverse pc is designed for land surveyors tpc desktop offers virtually any kind of land surveying mapping from start to finish in one package. Traverse adjustment by the method of least squares allows precision estimation of the adjusted coordinates of traverse points as well as derived bearings and distances.
