From a given starting point, or station, of known or assigned coordinates, the horizontal distance is measured to another point, then to another convenient point, and then to succeeding points, to close on the original point or on any point of known coordinates. A succession of such lines or courses forms a traverse. The horizontal angles between successive courses are measured with a transit or theodolite at each hub, or station.

From a known or arbitrarily assigned starting direction, the directions, or bearings, of successive traverse lines can thus be calculated. Plane geometry and plane trigonometry relationships are used to determine the coordinates of traverse stations. The north or south distance of a traverse course is its length multiplied by the cosine of the bearing; the east or west distance of a traverse course is its length multiplied by the sine of the bearing. Coordinates enable the plotting of the hubs to any scale on a grid that can serve as a plot or as control for further details drawn on a map or chart.

Traverses generally close back to the starting point to form a loop, or finish on another known position. The difference between the known finishing position and the calculated position for this point is the misclosure and indicates the accuracy of the traverse measurements and calculations.

For small projects Traverse calculation can be done but for large traverse point using a program can be helpful, so as to increase the precison and accuracy of computed data .
