## 5 differences between plane table survey and geodetic survey

Plane Surveying Geodetic Surveying Curvature of the earth is not taken in to consideration In this curvature of earth is considered. In plane Surveying, line joining any two points of triangle formed by any three points is considered as straight line and plane triangle are assumed to be plane angles. In geodetic surveying line joining …

Plane table survey is a graphical method of surveying in which the field works and the plotting is done simultaneously. It is particularly adopting small mapping. Plane table surveying is used for locating the field computation of the area of the field. Advantages of plane table survey: It is most suitable for preparing small scale …

## 2 types of compass survey

In a compass survey, the direction of the survey line is measured by the use of a magnetic compass while the lengths are by chaining or taping. Where the area to be surveyed is comparatively large, the compass survey is preferred, whereas if the area is small in extent and a high degree of accuracy …

## CHAIN SURVEYING (EQUIPMENTS, IMPORTANCE, AND METHODS)

## ERRORS THAT OCCUR IN CHAIN SURVEYING

An error is a mistake or shortcoming that happens during the survey process leading to wrong measurements. It is sometimes called discrepancies. The following are the type of errors or discrepancies in chain surveying Sources of Errors in Chain Survey and Their Correction The errors can be divided into three groups: Cumulative (systematic) errors Compensating …
