Surveying
•Surveying is the science and art of determining the
relative positions of points above, on, or beneath the
earth’s surface and locating the points in the field.
WhySurvey
Surveying allows us to get accurate and valid measurements of things that
are on the surface of the earth.
Phases of Survey
 Field Work
* Data Procurement Phase
 Office Work
 * Analysed
* Reduced to useful form by mathematical calculations
* Adjusted
* Frequently converted to graphical mode of Expression
PRIMARY DIVISIONS OF
SURVEYING
1.PlainSurveying
2.GeodeticSurveying
• The plain surveying is that type of surveying in which earth
surface is considered as a plane and the curvature of the earth is
ignored. In such surveying a line joining any two stations is
considered to be straight. The triangle formed by any three points
is considered as a plane triangle, and the angles of the triangle
are considered as plain angles.
• Surveying is carried out for a small area of less than 250 km2 . It is
carried out by local or state agencies like R & B department,
irrigation department, railway department.

GEODETICSURVEYING
• The geodetic surveying is that type of surveying in which the
curvature of the earth is takeninto account.
• It is generally extended over larger areas. the line joining any two
stations is considered as curved line.
• The triangle formed by any three points is considered to be spherical
and the angles of the triangle are considered tobe spherical angles.
• Geodetic surveying is conducted by the survey of India department
and is carried out for a larger area exceeding 250 km2

GPS was rapidly adapted for surveying, as it can give a position (Latitude,
Longitude and Height) directly, without the need to measure angles and
distances between intermediate points. Survey control could now be
established almost anywhere and it was only necessary to have a clear view
of the sky so the signal from the GPS satellites could be receivedclearly.

equipments
• Electronic Theodolite
• EDM – Electronic distance measurement eqp.
• Auto Level.
• Digital Level.
• Laser Level.
• Laser Distance meter
• T
otal station.
• GPS – global positioning system.
1.Electronic Thoedolite
• For precise surveys the vernier theodolites are
replaced by modern theodolites such as optical
and electronic theodolites.
• The electronic theodolites have optical
system to scan both horizontal and vertical
circles and display them digitally on a screen
2. EDM (Electronic Distance
meter)
1. EDM is Electronic Distance meter
2. Measurement of distance is done by a
modulated microwave or infrared
carrier signal
3. The distance is determined by emitting
and receiving multiple frequencies, and
determining the integer number of
wavelengths to the target for each
frequency.
3. Auto Level
• Now most commonly used levelling instruments are - Auto level.
• Auto level, as name sounds it has a auto level compensator and
corrects automatically if instrument goes out of level within it’s
range.
• With auto level:-
1. Survey work can be done fast,
2. Less chances of error,
3. Magnification available is more,
4. Range is more,
5. Image is erect so less chances of error.
4. Digital Level
• They are not popular instead auto levels are more
extensively used.
• The Trimble DiNi Digital Level : Determine accurate
height information 60% faster than with automatic
leveling
• Eliminate errors and reduce reworkwith digital
readings
• Transferdata to the office easily
• Measure to a field ofjust 30 cm
5. Laser Level
• The word laser is an acronym for Light Amplification
by Stimulated Emission of Radiation and is the name
applied to an intense beam of highly monochromatic,
coherent light.
• Laser rangefinders use these relationships to
calculate Distance
• Distance = speed of light * (time/2)
• The time refers to time of pulse to go from the
instrument to the tree and back again
• Byusing this Laser distance meter wecan
calculate the distance, area and volume
accurately
• We can use this in night also
6. GPS – Global Positioning
System.
What isGPS?
🠶 GPS, which stands forGlobal PositioningSystem, is
the only system today able to show you your exact
position on the Earth anytime, in any weather,
anywhere.
🠶 Global PositioningSystem –A network of satellites
(24 total – 21 in use, 3 spares) that continuously
transmit coded information which makes it
possible to precisely identify locations on earth by
measuring distance from the satellites.
7.EDM + Theodolite
• EDM is used to measure the horizontal
distances.
• Some EDM are attached with electronics
theodolite which has the adapter system.
• Some are advanced models which itself reads the
distance without theodolite
8.T
otal Station
• A Totalstation integrates the functions of a
Electronic theodolite for measuring angles,
an EDM for measuring distances, digital data
and a data recorder
• Angles and distances, coordinates and height
differences and many other items
can be computed, displayed and stored into
internal memory.

     GPS(GlobalPositioningSystems)Survey GPS wasrapidly adapted for surveying, as it can give a position (Latitude, Longitude and Height) directly, without the need to measure angles and distances between intermediate points. Survey control could now be established almost anywhere and it was only necessary to have a clear view of the sky so the signal from the GPS satellites could be receivedclearly.

    Traversing A Traversing iscircuit of survey lines. It may be open or closed. When the linear measurements are done with a chain and a tape and the directions or horizontal angles are measured with a compass or a theodolite respectively the survey is called traversing.

    1.Electronic Thoedolite • Forprecise surveys the vernier theodolites are replaced by modern theodolites such as optical and electronic theodolites. • The electronic theodolites have optical system to scan both horizontal and vertical circles and display them digitally on a screen

    2. EDM (ElectronicDistance meter) 1. EDM is Electronic Distance meter 2. Measurement of distance is done by a modulated microwave or infrared carrier signal 3. The distance is determined by emitting and receiving multiple frequencies, and determining the integer number of wavelengths to the target for each frequency.

    3. Auto Level •Now most commonly used levelling instruments are - Auto level. • Auto level, as name sounds it has a auto level compensator and corrects automatically if instrument goes out of level within it’s range. • With auto level:- 1. Survey work can be done fast, 2. Less chances of error, 3. Magnification available is more, 4. Range is more, 5. Image is erect so less chances of error.

    4. Digital Level •They are not popular instead auto levels are more extensively used. • The Trimble DiNi Digital Level : Determine accurate height information 60% faster than with automatic leveling • Eliminate errors and reduce reworkwith digital readings • Transferdata to the office easily • Measure to a field ofjust 30 cm

    5. Laser Level •The word laser is an acronym for Light Amplification by Stimulated Emission of Radiation and is the name applied to an intense beam of highly monochromatic, coherent light. • Laser rangefinders use these relationships to calculate Distance • Distance = speed of light * (time/2) • The time refers to time of pulse to go from the instrument to the tree and back again • Byusing this Laser distance meter wecan calculate the distance, area and volume accurately • We can use this in night also

    6. GPS –Global Positioning System. What isGPS? 🠶 GPS, which stands forGlobal PositioningSystem, is the only system today able to show you your exact position on the Earth anytime, in any weather, anywhere. 🠶 Global PositioningSystem –A network of satellites (24 total – 21 in use, 3 spares) that continuously transmit coded information which makes it possible to precisely identify locations on earth by measuring distance from the satellites.

    8.T otal Station • ATotalstation integrates the functions of a Electronic theodolite for measuring angles, an EDM for measuring distances, digital data and a data recorder • Angles and distances, coordinates and height differences and many other items can be computed, displayed and stored into internal memory.
