Classification Of Surveying(Survey-Types)

 Classification Of Surveying

Different Type of surveying

What Are The Classification Of Surveying?

Surveying may be classified on the following basis:

(i) Nature of the survey field
(ii) Object of survey
(iii) Instruments used and
(iv) The methods employed.

                      Classification Of Surveying

• Classification Based on Nature of Survey Field

On this basis survey is also classified as land survey, marine or hydraulic survey and astronomical survey.

• Land Survey. It involves measurement of various objects on land. This type of survey is also more classified as given below:

 (a) Geographics Survey or geographical survey : it's meant for plotting natural options like rivers, lakes, forests and hills as well as man made features like roads, railways, towns, villages and canals.

(b) Cadestal Survey: It is for marking the boundaries of municipalities, villages, talukas, districts, states etc. The survey created to mark properties of people additionally return beneath this class.

(c) town Survey: The survey created in reference to the development of streets, water supply and sewage lines fall under this category.

• Marine or Hydrographic Survey. Survey conducted in ocean depth of water at numerous points in bodies of water like sea, river and lakes fall under this category. Finding depth of water at specific points is thought as sounding.
• Astronomical Survey. And observations created to heavy bodies like sun, stars etc., to the locate absolute position of points on the earth and for the purpose of calculating local time is known as astronomical survey.

• Classification Based on Object of Survey:-

On the idea of object of survey the classification are often as engineering survey, military survey, mines survey, geological survey and archeological survey.

(a) Engineering Survey: the target of this kind of survey is to gather knowledge for planning applied science comes like roads, railways, irrigation, water supply and sewage disposals. These surveys are further sub-divided into:

Reconnaissance Survey for determining feasibility and estimation of the scheme.

Preliminary Survey for aggregation additional info to estimate the price of the project, and

Location Survey to line the work on the bottom.

(b) Military Survey: This survey is supposed for understanding plans of strategic importance.

(c) Mines Survey: this can be used for exploring mineral wealth.

(d) geologic Survey: This survey is for locating completely different strata within the earth’s crust.

(e) archaeologic Survey: This survey is for unearthing relics of antiquity.

• Classification Based on Instruments Used

                                     

Surveying equipment

Based on the instruments used, surveying may be also classified as:

(i) Chain survey

(ii) Compass survey

(iii) Plane table survey

(iv) Theodolite survey

(v) Tacheometric survey

(vi) trendy survey mistreatment electronic distance meters and total station

(vii) Photographic and Aerial survey

The survey is schooled to students chiefly supported this classification.

• Classification Based on Methods Employed

On this basis measure is assessed as triangulation and traversing.

(i) Triangulation: during this methodology management points ar established through a network of triangles.

(ii) Traversing: during this theme of creating management points consists of a series of connected points established through linear and angular measurements. If the last line meets the place to begin it's known as as closed traverse. If it doesn't meet, it's referred to as open traverse.
