3. PLANE TABLE SURVEYING
• AIM:- Tostudy and use the plane table survey by
radiation and intersection method.
• THEORY: Plane tabling is a graphical method of
surveying in which field book and plotting are done
• simultaneously. It is most suitable for filling in detail
about between the stations previously fixed by
• triangulation. It is particularly adopted on small scale
or medium scale marking in which detail is required
• for graphical survey.

4. •Accessories for plane table survey:
• 1)Drawing board-Made up of well-seasoned wood suchas teak
or pine and its size is 40x30cmto
• 75x60cm.It is mounted on midpoint after levelling about interior
axis.
• 2)Alidade- Alidade consistsof brass or metal or woodstraight
edge or ruler about 50cmlongline
• levelled edge. It is used for sighting the object to the located
point.
• 3)Trough compass- A trough compass or circular box compass
with magnetic needle at centre is used for
• measuring north direction on drawing sheet.
• 4)U-fork – Once the line of fork/plumb bob is attached and upper
arm is same what to indicate which
• point on table is vertically over the station point on ground.
• 5)Bubble Tube: There is a bubble in the tube when thebubble
comes exactly in the centre of the tube
• then indicates that the bubble corner is exactly horizontal to
ground.

8. METHODS OF PLANE TABLE
SURVEYING:
• 1.Radiation: In this method point is located on plan by drawing a ray
from plane table stat. to the
• point and plotting to scale along the ray. The distance measured from
station to the point. This
• method is suitable for small area which can be commanded from a
single station.
• Procedure –
• 1)Select point Psuchthat all points to be located visible from it.
• 2)Set up the table at Cand after levelling it clamp theboard.
• 3)Using U-fork selected point Cis traversed to table.
• 4)Mark direction of magnetic meridian with the help of trough compass
right top corner of sheet.
• 5)Centring the alidade on Cand sight point. Pto Q, R,S,Tetc. and draw
rays on table along them
• 6)Measure distance CP,CQ,CR,CS,CT by chain or tape.
• 7) Taking suitable scale plot these distances on sheets

10. • Intersection method- In this method point is fixed on plan by the
intersection of rays drawn from
• the two instrument stations. The line joining these stations is called base line. It is
suitable when distances
• are very large and having observations between them.
• Procedure-
• 1)SELECTTWO POINTS LAND M IN A COMMANDING POSITION

12. DUMPY LEVEL / AUTO LEVEL
• Aim:- Tostudy the essential parts of dumpy level &
reduction of levels.
• Apparatus:- Dumpy level, tripod stand, leveling staff
etc.
•Theory:-The dumpy level is a simple and compact
instrument; the telescope is rigidly fixed to its
• supports it can be rotated about its longitudinal axis.
Level tube is permanently placed so that axis lies in
• same vertical plane. A focusing screw near the eye
piece provided to get clear image of the object and to
• bisect cross hair.

13. •Bench mark: - It is point of known elevation. It is
used either as a starting point or as a check point before
• closing.
•Axis of telescope: - It is line joining the object,
optical centre of the glass to the centre of the eye piece.
•Line of collimation (Line of sight):-
It is line joining intersection of cross hair to the optical centre
of the
• glass.

14. PARTS OF DUMPY LEVEL:-
• 1. Tripod: - The tripod consists of three legs, lower ends of it fitted with steel
shoes.
• 2.Leveling head: - It consistsof two parallel triangular
plates to supports the foots screws.
• 3. Foot Screws: - It is provided between trivet and tribatch, by turning the
screws the tribatch can be
• raised or lowered to bring bubble tube at the centre.
• 4.Telescope: - It consistof an object glass and eye piece on
opposite end, a diaphragm isfixed with
• the telescope just in front of eye piece.
• 5. Bubble tube: - Two bubble tubes one longitudinal and one cross bubble
provided right angles to
• each other. Thebubble isbrought to the centre with the
help of foot screws.
• 6. Compass: - A compass is provided just below the telescope for
taking magnetic bearing of a line
• required.

15. REDUCTION OF LEVEL
• H.I method:-
• The reduced level of the line of collimation is said to
be the height of the instrument. In this system height
• of the line of collimation is found out by adding back
side reading to the R.Lof bench mark on which BS
• is taken. Then RLof intermediate points and the
change point are obtained by subtracting the
respective
• staff reading from the height of instrument (HI). Tofind
new HI of change point BSis taken on last point

16. THEODOLITE SURVEYING
• Aim: - Tomeasure direct angle, deflection angle and
magnetic bearing of line by using theodolite
• Apparatus: - Transit theodolite, ranging rod, pegs etc.
• Direct Angle:
• The angle measured clockwise from preceding line to
the following line. They may vary 0°to 360°.
• Procedure:-
• - Set up the theodolite at O and level it accurately set
vernier A to 0°0΄0˝.Loosethe lower plate
• and take back sight on A.
• - Loose upper plate rotate telescope clockwise and
bisect Bexactly read both vernier.

17. • Plunge the telescope turns the
instrument about its outer axis and take
back sight on A the reading
• on vernier A will be same as in Step 1.
• - Loose the upper plate, turn the
telescope clockwise and again bisect B
exactly.
• - Read both verniers. The reading will be
twice the previous, <AOB will be obtain
by dividing the
• final reading by 2.

19. DEFLECTION ANGLE
• Deflection angle is the angle which the survey line
makes with the prolongation of preceding line.
• Procedure:-
• Set up the theodolite at Band level it accurately.
• - With both plates clamp the vernier A reading
0°0΄0˝take back sight on A. Plunge the telescope
• to direct the line of sight AB. Loosen the upper plate
and turn the telescope clockwise to take
• fore sight C.Read both verniers. The mean of two
verniers reading gives the approximate value
• of deflection at B&clamp upper clamp.
• -

20. • Loosen the lower clamp and turns the
telescope horizontally to back sight on A. The
vernier will
• read the same reading as in step 4and
telescope transited. Plunge the telescope and
unclamped
• the plates and again bisect C.Read both
verniers. Find the mean of final readings. Thus
the
• deflection angle is doubled and hence one half
of its average value given accurate value of
• deflection angle at B

22. MAGNETIC BEARING
• The angle which a line makes with the magnetic
meridian is called a magnetic bearing of a line.
• Procedure:-
• For measuring hearing through compass or tabular
compass is attached to theodolite.
• Set the vernier A to 0°0΄0˝of the horizontal circle after
setting theodolite over 0and level it.
• Loosen the lower clamp magnetic needle is then
realized to swing on pivot of compass. Rotate
• the instrument till needle roughly point to the north by
using lower tangent screw and correct
• direction of magnetic needle is obtain

23. • Loose the upper clamp and direct the telescope
towards A and bisect it exactly by using upper
• clamp and upper tangent screw. Read both verniers.
• - Change the face and repeat the process. The average
of two values gives correct bearing of line
• AB.
