Geological survey – Civil Engineering Projects

Classification of Surveys according to their Purpose

In our previous article, we discussed division and classification of surveys based on various factors such as Purpose, instruments, field of work, method of work etc.

In this article, we will discuss different types of surveys carried out for various purposes in the field of Surveying…

Mine Survey

Mine survey involves exploration of mineral wealth in the country. This would include minerals such as Gold, copper, coal, silver etc. between the earth’s crust.

Classification of Survey

Study of classification of surveys is a major part of the study of Surveying as a whole. The surveys are conducted using various different instruments. The use of instruments depend upon its availability and suitability to the site.

Surveys are classified as following:

According to the instruments used for the survey
According to the purpose of the survey
According to the method employed for the survey
According to the field of work

In this article, we will list out the classification in each and category and study them in detail…

According to the instruments used

Chain Survey

Chain Survey is conducted using different lengths of chains specifically made for the surveying purpose.

Compass Survey

As the name itself suggests, the compass is used for the purpose of the survey.

Plane table Survey

Plane table is used for the purpose.

Levelling

Theodolite Survey

Theodolite is an instrument that is useful for conducting accurate surveys.
