Classification of Surveys and Surveying Methods in Engineering





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:

  1. According to the instruments used for the survey
  2. According to the purpose of the survey
  3. According to the method employed for the survey
  4. 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.

According to the purpose of Surveying

  1. Mine Survey
  2. Geological survey
  3. Archaeological survey
  4. Military survey

According to the method employed

  1. Triangulation Survey
  2. Transverse Survey

According to the field of work

  1. Land Survey
  2. Hydrographic or marine survey
  3. Aerial Survey

Land Survey is further classified into following categories:

  1. Topographical Survey
  2. Cadastral Survey
  3. City Survey
  4. Engineering Survey

Engineering Survey is further classified into three categories:

  1. Reconnaissance Survey
  2. Preliminary Survey
  3. Location Survey

We will discuss each of these different types of surveys and survey methods in detail in our successive articles…
