# Introduction of Traversing in Surveying

Surveying is the process of collecting data about specific points on the Earth’s surface. The most common type of surveying is land surveying, which is used to determine the boundaries of land parcels, to create maps, and to determine the elevation of the land surface. Traversing is a surveying technique that involves taking measurements from one point to another in order to determine the distance between them. It is typically used when the points being measured are too far apart to be measured directly. Traversing is a relatively simple process that can be completed with just a few people and a few basic tools.

## Objectives of Traversing in Surveying

• There are several objectives of traversing in surveying, which include:

1

• Establishing control points for subsequent surveys
2
• Determining the size, shape, and contours of a piece of land
3
• Finding the boundaries of a piece of land
4
• Identifying features on a piece of land
5
• Measuring distances and angles between points on a piece of land

## Types of Traverse in Surveying

• There are many types of traverse in surveying depending on the needs of the survey
• Some common types of traverse are open traverse, closed traverse, balanced traverse, and chain traverse.

## Balancing The Traverse

• To balance the traverse, or to keep it in equilibrium, you must keep the pulley system, anchored by the belt, in the middle of the plank
• You do this by adjusting your body weight on either side of the plank
• The heavier you are, the more you will have to adjust your body to keep the system in the middle.

## Adjustment of Angular Error and Bearing

• If the true bearing to a station is not known, an assumed bearing may be used
• The amount by which the assumed bearing must be corrected is the angular error, which may be either plus or minus
• The assumed or uncorrected bearing is usually written with the plus or minus sign before the number; thus, +36°10′ would mean an assumed or uncorrected north-bearing of 36°10′
• The amount of the correction may be stated in several ways
• Sometimes the entire correction is given in minutes, without regard to whether it is plus or minus
• In other cases, only the amount of plus correction is given; the minus correction is then obtained by subtraction
• The amount of correction may, however, be stated in degrees, minutes, and seconds, or in decimal degrees
• Bearing is the horizontal angle between the direction of an object and another object or reference point

• There are four quadrants in which a bearing can fall: north, south, east, or west
• Angular error is the difference in the angle between the assumed bearing and the true bearing
• The amount of correction is usually given in minutes without regard to whether it is plus or minus
• The assumed or uncorrected bearing is usually written with the plus or minus sign before the number; thus, +36°10′ would mean an assumed or uncorrected north-bearing of 36°10′
• If the true bearing is not known, an assumed bearing may be used and

## Conclusion

The process of traversing is a very important surveying technique that helps to measure the horizontal distances between two points. This technique is very helpful in measuring large areas of land. Traversing is also helpful in measuring the angles between the lines.
