  • 3. Surveying Instruments
    HOW WE USE INSTRUMENT
    DURING SURVEYING
  • 4. Surveying Instrument
    Instruments used in surveying operations to measure vertical angles, horizontal angles, and distance.
  • 5. Tripod
    A surveyor's tripod is a device used to support any one of a number of surveying instruments, such as theodolite, total stations ,levels or transits.
  • 6. Level staff
    A level staff, also called levelling rod, is a graduated wooden or aluminum rod, the use of which permits the determination of differences in elevation
    In the photograph on the right, both a metric (left) and imperial (right) levelling rod are seen. This is a two-sided aluminum rod, coated white with markings in contrasting colours. The imperial side has a bright yellow background.
  • 7. Total Station :-
    A total station is an electronic/optical instrument used in modern surveying
    To read distances from the instrument to a particular point.
  • 8. Clinometer
    An instrument used by surveyors in order to measure an angle of inclination or elevation
  • 9. Line of sight

    90 line on protractor
    weight
  • 10. Uses of Clinometers
    Indicating pitch and roll of vehicles, sail boats, and aircraft.
    Monitoring boom angle of cranes and material handlers.
    Measuring the "look angle" of a satellite antenna towards a satellite.
    Measuring movements in walls and/or the ground in civil engineering projects
    Measuring the angle of drilling in well-logging applications.
    Rollover warning, to alert equipment operator of possible tip over condition
    Determining the angle of the earth's magnetic field in respect to the horizontal plane.
    Measuring steepness of a ski slope. (<10o for beginners, 10o-20o "green", 15o-25o "blue", 25o-35o "black", 35o-45o "double black")
  • 11.  Compass
    A compass is a navigational survey instrument used for determining the “directions” which is relative to the Earth's magnetic pole
    • A compass can be used to calculate “heading” used with a “sextant” to calculate latitude” and with a “marine chronometer” to calculate “longitude”
  • GPS
    GPS
  • 12. DEVOLPMENT
    ERATH QUAKE SCENCE
    PLANS DIRECTION
    VEHICALS
  • 13. ELEMENTS
    The Space Segment
    The User Segment
    The Control Segment
  • 14. The Space Segment
    24 Satellite
  • 15. The User Segment
    Receiver
  • 16. The Control Segment
    Ground station
  • 17. Principle of Gps
    Measurement of distance between satellite and receiver
    Wgs84
  • 18. Use of Gps in now a days
    Military use
    Every day's life
  • 19. Theodolite
    Most important application is measuring horizontal and vertical angles
    Horizontal distances and determine elevations
  • 20. How to use
    A theodolite must be mounted on a level tripod or stand from where the user can observe.
    The observer can take a reading by looking through the telescope and adjusting the vertical crosshairs to match the extreme left of the survey target.
  • 21. Prism
    • Prism
    • 22. Consider the offset,
    • 23. The thread size,
    • 24. When working with Total Stations that require a target
  • That ‘s All Our Presentation
