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.

The work of the surveyor consists of 5 phases
1. Decision Making – selecting method, equipment and
final point locations.
2. Fieldwork & Data Collection – making measurements
and recording data in the field.
3. Computing & Data Processing – preparing
calculations based upon the recorded data to
determine locations in a useable form.
4. Mapping or Data Representation – plotting data to
produce a map, plat, or chart in the proper form.
5. Stakeout – locating and establishing monuments or
stakes in the proper locations in the field.

Categories of Surveying
1. Plane Surveying – surveying with the reference
base for fieldwork and computations are assumed to
be a flat horizontal surface.
2. Geodetic Surveying – surveying technique to
determine relative positions of widely spaced points,
lengths, and directions which require the
consideration of the size and shape of the earth.
(Takes the earth’s curvature into account.)

Types of Surveys
1. Photogrammetry – mapping utilizing data obtained by camera or other sensors carried in airplanes or satellites.
2. Boundary Surveying – establishing property corners, boundaries, and areas of land parcels.
3. Engineering Surveying – providing points and elevations for the building Civil Engineering projects
4. Topographic Surveying – collecting data and preparing maps showing the locations of natural man-made features and elevations of points of the ground.
5. Route Surveys – topographic and other surveys for long – narrow projects associated with Civil Engineering projects (Highways, railroads, pipelines)

Brief History of Surveying
1. Surveying had it’s beginning in Egypt about 1400 BC
2. Greeks: expanded Egyptian work and developed Geometry
3. Romans: developed surveying into a science to create the
Roman roads, aqueducts, and land division systems.
4. Middle Ages: land division of Romans continued in Europe.
5. 18th & 19th Century in the New World: the need for mapping
and marking land claims caused extensive surveying,
especially by the English.
6. 20th Century and Beyond: As technology advanced, population
increased, and land value caused development of licensure for
surveyors in all countries

Modern Surveying
• By the 1970’s, relatively small, lightweight and easy-to-use electronic distance measuring devices, called EDM’s were in use.
• The advance of technology and miniaturization of electronic components enabled the building of theodolites that measure angles electronically, called Electronic Theodolite
• Combination of an electronic theodolite and electronic distance meter, and software running on an external laptop computer known as a data collector, called Total Station
• The Global Positioning System (GPS) was designed for military applications. Its primary purpose was to allow soldiers to keep track of their position and to assist in guiding weapons to their targets
• A computerized data base management system for capture, storage, retrieval, analysis, and display of spatial data, called GIS

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.

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

GPS – Global Positioning System.
What is GPS
• GPS, which stands for Global Positioning
System, is the only system today able to
show you your exact position on the Earth
anytime, in any weather, anywhere.
• Global Positioning System – 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.

Basic Principle of Total Stations
1. These instruments are measuring the distances of prism
poles mounted with prisms with the help of Laser beam or
Infrared rays.
2. These signals are emitted by the instrument EDM and
reflected back to instruments by the prism mounted on the
prism poles.
3. The time interval between emission and reception helps
to calculate the distance as the speed of these signals are
precisely known. D = (t/2) x v
D-Distance, t-Total time taken, v-Velocity

What way it is different from conventional methods?
Each point will be named with its Id/Code.
No paper work, as calculations are performed automatically.
Combines the use of leveling instrument , Theodolite compass
etc. and does boundless operations.
Surveying can be done during night hours also if the prism pole
is illuminated for emergency.
More costly and self lubricated.
Needs one surveyor and other two persons to hold prism.
Person handling these instruments need not be conversant with
survey theory but essentially a computer literate and must possess
sufficient aptitude.

Refractorless Total Station
For those targets such as wire
pole, wire, cliff, hill,earth,timber pile,
etc which are not easy or even
impossible to reach, reflectorless
distance measurement can complete
the measurement task easily

The SRX from Sokkia is a fully-
robotic, fully-tracking and auto-
pointing robotic total station, with on-
demand target reacquisition
Sokkia’s SRX has Bluetooth wireless
technology for cable-free use,
making this single-operator total
station even more convenient.

long traverses or resections. Just set up
SmartStation and let GPS determine the
position.Then measure and stake out
with the total station.
SmartStation’s modular design gives you
all the options.
Undertake any type of job.
Save time and money.
Increase your productivity
and profits.
