it indicates the need to obtain an overall
picture of what is required before any type of survey work is undertaken. In land
surveying, this is achieved during the reconnaissance study

Q

The data collected in any survey must be presented in a form which allows the
information to be clearly interpreted and understood by others. This presentation
may take the form of written report, bills of quantities, datasheets, drawings and
in land surveying maps and plan showing the features on the land.

Q

It involves measurement of various objects on land

A

Land Survey

21
Q

It is meant for plotting natural features like rivers, lakes, forests and hills as well as man made features like roads, railways,
towns, villages and canals.

A

Topographic Survey

21
Q

It is for marking the boundaries of municipalities, villages, talukas, districts, states etc. The survey made to mark properties of individuals also come under this category.

A

Cadastal Survey:

21
Q

Survey conducted to find depth of water
(sounding) at various points in bodies of water like sea, river and lakes fall
under this category. Finding depth of water at specified points is known as
sounding.

A

Marine or Hydrographic Survey

22
Q

The survey made in connection with the construction of
streets, water supply and sewage lines fall under this category.

A

City Survey:

23
Q

Observations made to heavenly bodies like sun, stars
etc., to locate absolute positions of points on the earth and for the purpose of
calculating local time is known as astronomical survey

A

Astronomical Survey

23
Q

On this basis survey may be classified as land survey, marine or hydraulic survey
and astronomical survey.

A

Classification Based on Nature of Survey Field

24
Q

On the basis of object of survey the classification can be as engineering survey,
military survey, mines survey, geological survey and archeological survey.

A

Classification Based on Object of Survey

25
Q

The objective of this type of survey is to collect data for
designing civil engineering projects like roads, railways, irrigation, water supply
and sewage disposals.

A

Engineering Survey

26
Q

Engineering Survey are further sub-divided into:

A

-Reconnaissance Survey
-Preliminary Survey

27
Q

for determining feasibility and estimation of the scheme.

A

Reconnaissance Survey

28
Q

for collecting more information to estimate the cost of the project, and Location Survey to set the work on the ground.

A
  • Preliminary Survey
29
Q

This survey is for working out plans of strategic importance.

A

Military Survey

30
Q

This is used for exploring mineral wealth.

A

Mines Survey:

31
Q

This survey is for finding different strata in the earth’s crust.

A

Geological Survey

32
Q

This survey is for unearthing relics of antiquity.

A

Archeological Survey

33
Q

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

A

i. Chain survey
ii. Compass survey
iii. Plane table survey
iv. Theodolite survey
v. Tacheometric survey
vi. Modern survey using electronic distance meters (EDM) and total station
vii. Photographic and Aerial survey

34
Q

On this basis surveying is classified as triangulation and traversing.

A

Classification Based on Methods Employed

35
Q

In this method control points are established through a network of triangles.

A

Triangulation

36
Q

In this scheme of establishing control points consists of a series of
connected points established through linear and angular measurements.

A

Traversing

37
Q

in Traversing If the last line meets the starting pointit is called ____

A

closed traverse

38
Q

in Traversing If it does not
meet it is known as ______

A

open traverse

39
Q

Representation of larger areas are
called ____

A

maps

39
Q

defined as the graphical representation of the
features on, near or below the surface of the earth as projected on a horizontal
plane to a suitable scale

A

plan

39
Q

the ratio of the distance marked on the plan to the corresponding distance on the ground.

A

scale

39
Q

Representation of a particular locality in a municipal area is a _______

A

plan

40
Q

Representation of a Scale :

A

A. Engineer’s scale
B. Representative Fraction (R.F)
C. Graphical scale

41
Q

Engineer’s scale :

A

1 cm = 50 m

42
Q

It is the ratio of the distance on the map to the corresponding distance on the
ground taken as same units.

A

Representative Fraction (R.F)

43
Q

-is a line drawn on the map so that its map distance corresponds
to a convenient units of length on the ground.

-It has the advantage over the numerical scales that the distances on the maps can
be determined by actual scaling even when the map has shrunk.

A

Graphical scale
