This document discusses various types of land and engineering surveys. It begins by introducing Dr. Radhanath Sikdar, a famous Indian surveyor born in 1813 who measured the height of Mount Everest. It then lists the names and contact details of the team members who prepared the document. The document goes on to describe different types of surveys including coal mine surveys, hydrographic surveys, reciprocal leveling, contour mapping, and transmission line surveys. It concludes by thanking the reader and offering to answer any additional questions.

4. Dr.
RADHANATH
SIKDAR
(The greatest surveyor in the
world. Because he measured
the high of Mount Everest by
the Great Trigonometrical
Levelling.)
Born:- 1813
Place:-Jorasanko of North
Kolkata
Father:-TITURM
Youngest son of his father.
Died:- 17 May, 1870

5. ABOUT Dr. RADHANATH SIKDAR
He is not just a surveyor he is also a mathamathion
He is a brilliant student just at the age of eleven. He was then
send to Hindu college(presently known Presidency
University).At this time he came to contact two great teacher
LUI VIVIAN DEROZIO and Dr. JOHN TYTIER . At that time
the work on land surveying was at it’s peak in India and a new
department called Trigonometrical Survey(GTS). Dr. JOHN
TYTIER referred RADHANATH SIKSAR name to Jorge
Everest, surveyor General, India. He develop some formula of
Trigonometrical Survey.

6. TYPES OF SURVEY
 Cole Mine Survey
 Hydrographic Survey
 Reciprocal Levelling
 Slices of Contour
 Transmission Line Survey

7. COLE MINE SURVEY

8. ABOUT COLE MINE SURVEY
 Mine Surveying is done in mines and tunnels below the ground
surface. Therefore, mine surveying is also called Underground
Surveying.
 The Underground Surveys are generally more difficult than
surface surveys because of unfavorable conditions, such as
poor light , smoky atmosphere and humid surrounding.

9. TYPES OF COLE MINE SURVEY
 Surface Mining:
 Typically occurs at depths above 180 ft.
 Most common form in Wyoming
 Underground Mining
 Typically occurs at depths below 300 ft.
 Accounts for 60% of world coal production

10. HYDROGRAPHIC SURVEY

11. ABOUT HYDROGRAPHIC SURVEY
 Branch of science that deals with the measurement of bodies of
water
 Deals with the physical features of the navigable portion of the
earth’s surface and adjoining coastal areas.
 Sounding –measurement of depth below the water surface
 Applications of sounding:
 Making nautical charts for safety of navigation
 Development and engineering projects such as piers, dams
and bridges
 Scientific and academic studies

12. USE OF HYDROGRAPHIC SURVEY
 Preparation Of Nautical Charts
 Assessing Silting In Harbors
 For Planning Dredging
 Determination Of Contour
 For Lake & River Survey
 For Design Of Projects Like
Dams,Bridges,Reserviours etc.

13. RECIPROCAL LEVELLING

14. ABOUT RECIPROCAL LEVELLING
Reciprocal leveling is employed to determine the
difference in elevation between two points when it is
difficult or impossible to keep back sights and foresights
short and equal.

15. SLICES OF CONTOUR

16. ABOUT SLICES OF CONTOUR
 Contouring is a makeup technique that uses cosmetics to
define, enhance and sculpt the structure of the face[1] or
other body parts, such as breasts.[2]
 Contouring is usually produced by placing a warm or cool
toned colour that is one or two shades darker than the skin
color in areas such as in the hollows of the cheeks, on the
side of the nose, and on the temples to give a shadow and
slimming effect. It can be complemented with a highlighter
that is one or two shades lighter than the skin color on
areas of the face that is more prominent such as on the
apples on the cheeks and the tip of the nose or the t-zone.

17. TRANSMISSION LINE SURVEY

18. ABOUT TRANSMISSION LINE SURVEY

Consultancy Services related to electrical engineering
transmission line survey. These services are being
provided strictly in compliance with the ISO and CMM
standards. We are equipped with latest technology and
advanced machines which enable our clients to guide our
