Plane Table Surveying is a graphical method of survey in which the field observations and plotting are done simultaneously.
It is simple and cheaper than theodolite survey. It is most suitable for small scale maps.
The plan is drawn by the surveyor in the field, while the area to be surveyed is before his eyes. Therefore, there is no possibility of omitting the necessary measurements.
In Compass survey chain or tape is used for linear measurements and compass is used for fixing direction.
In compass freely suspended magnetic needle directs to north- south and the bearing of line is obtained by line of sight.
When large area are involved, compass surveying is used.
There are mainly two methods of land measurement.
Triangulation survey
Traverse survey
DEFINATION :-
The art of determining the relative heights of different points on , below or above the surface of the earth
Deals with measurement in – vertical plane

Or A contour line
is a line that passes through points having the same elevation.
contour interval

consecutive contours is called the contour interval

-The choice of suitable contour interval depends on several
factors.

-Characteristics of contour lines.
-Contours are used by Engineers to:
-Methods of locating contour:
A- The direct methods
1- Level and staff method.
2- Plan table and alidade method.
Direct method procedure:
In this method the actual contour is pegged out on the ground and its
planimetric position located. A back-sight is taken to an appropriate BM and
the HPC of the instrument is obtained, say( 34.800m.) A staff reading of
0.800m would then place the foot of the staff at the( 34m )contour level. The
staff is then moved throughout the terrain area, with its position pegged at
every 0.800m reading. In this way the 34m contour is located. Similarly a
staff reading of (1.800m) gives the 33m contour and so on. The planimetric position of the contour needs to be located using an appropriate survey technique.

Introduction of surveying_Surveying, Civil EngineeringA Makwana
Surveying is the art of determining the relative positions of points on, above or beneath the surface of the earth.
The relative positions are determined by measuring horizontal distances, vertical distances, horizontal angles and vertical angles accurately using various surveying instruments.
Levelling is a branch of surveying dealing with determination of relative heights of the point on the surface of the earth in a vertical plane.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

4. INTRODUCTION
“Surveying is the art of and science of determining the relative
positions of various points or stations on the surface of the
earth by measuring the horizontal and vertical distances,
angles, and taking the details of these points and by preparing a
map or plan to any suitable scale.”
5. OBJECTIVE OF SURVEYING
The object of surveying is to prepare a map or plan to show
the relative positions of the objects on the surface of the earth.
The map or plan is drawn to some suitable scale. It also
shows boundaries of districts, states, and countries too. It also
includes details of different engineering features such as
buildings, roads, railways, dams, canals etc.
To prepare a topographical map which shows hills, valleys,
rivers, forests, villages, towns etc.
To prepare a cadastral map which shows the boundaries of
fields, plots, houses and other properties..
To prepare an engineering map which shows the position of
engineering works such as buildings, roads, railways, dams,
canals.
6. LEVELING
• Leveling is a branch of surveying which deals with
the measurement of relative heights of different
points on, above or below the surface of the earth.
Thus in leveling, the measurements (elevations) are
taken in the vertical plane.
7. TYPES OF LEVELLING
The following are the different types of levelling
Simple levelling
Differential levelling
Fly levelling
Profile levelling
Cross sectioning and
Reciprocal levelling.
8. Simple Levelling
It is the method used for finding difference between the
levels of two nearby points
9. Differential Levelling
If the distance between two points A and B is large,
it may not be possible to take the readings on A and
B from a single setting.
In such situation differential levelling is used. In
differential levelling the instrument is set at more
than one position, each shifting facilitated by a
change point.
10. Plane table surveying
The plane table surveying is the fast method of
surveying. In this type of surveying plotting of the plan
and field observations can be done simultaneously. In
case of plane table surveying Geometrical conditions
of site are manuscript in the map sheet using plane
table and alidade after that topographic details are
arranged on the map.
11. Equipment Used in Plane Table Survey
General equipment used for conducting plane table
survey are
Plane table
Alidade for sighting (telescopic or simple)
Plumb bob and plumb fork
Compass
Spirit level
Chain
Ranging rods
Tripod
Drawing sheet and drawing tools
Paper clips or screws
12. Methods of Plane Table Surveying
Generally there are four methods are available to perform
plane table surveying. They are
Radiation
Intersection
Traversing
Resection
1 RADIATION: In this method, plane table is located at
one point “o” as shown in fig. and perform the whole
from that point. From point O, sight the points A,B,C,D
and E using alidade, locate and plot the points as
a,b,c,d and e in the drawing sheet.
13.
14. Intersection
In this method we can locate the point by plotting
two rays from two known stations. As shown in
figure, P and Q are the known station. First the
equipment is placed on P and plot the lines by
sighting the stations A, B and Q. then shift the
equipment to station Q and plot the lines by sighting
stations A, B and P. Finally, the intersection of A and
B rays is the required location of point of
intersection.
15. Traversing
Traversing is the connection of series of straight
lines. In case of traversing, plane table is located at
one point for suppose A as shown below. From that
point sight towards B and measure the distance AB.
Then shift the plane table to point B and sight
towards A and measure BA. Average distance of AB
and Ba are plotted to scale in drawing sheet. Then
Sight the point C from B and measure BC and
repeat the same procedure until last point. Conduct
some checks at some points. Finally traverse lines
are plotted on the drawing sheet.

18. Compass surveying
Compass surveying is the branch of surveying in
which the position of an object is located using angular
measurements determined by a compass and linear
measurements using a chain or tape. Compass
surveying is used in following circumstances:
If the surveying area is large, chain surveying is not
adopted for surveying rather compass surveying is
employed.
If the plot for surveying has numerous obstacles and
undulations which prevents chaining.
If there is a time limit for surveying, compass
surveying is usually adopted
19. Magnetic compass
Magnetic compass is used to find out the magnetic
bearing of survey lines. The bearings may either
measured in Whole Circle Bearing (W.C.B) system
or in Quadrantal Bearing (Q.B) system based on
the type of compass used. The basic principle of
magnetic compass is if a strip of steel or iron is
magnetized and pivoted exactly at centre so that it
can swing freely, then it will establish itself in the
magnetic meridian at the place of arrangement.
Major types of magnetic compass are:
Prismatic compass
Surveyor’s compass
Level compass
20. Prismatic compass
Prismatic compass is a portable magnetic compass
which can be either used as a hand instrument or can
be fitted on a tripod. It contains a prism which is used
for accurate measurement of readings. The greatest
advantage of this compass is both sighting and
reading can be done simultaneously without changing
the position.
