Surveying instruments

  1. 1.
  2. 2. Group A<br />Arsalan Rehman <br />Asim Rafique<br />M.Faraz Zafar<br />Safdar Mahmood (CR)<br />Mukarram Rabbani <br />Nasir javed<br />
  3. 3. Surveying Instruments<br />HOW WE USE INSTRUMENT <br /> DURING SURVEYING<br />
  4. 4. Surveying Instrument<br />Instruments used in surveying operations to measure vertical angles, horizontal angles, and distance.<br />
  5. 5. Tripod<br />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.<br />
  6. 6. Level staff<br />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<br />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. <br />
  7. 7. Total Station :-<br />A total station is an electronic/optical instrument used in modern surveying<br />To read distances from the instrument to a particular point.<br />
  8. 8. Clinometer<br />An instrument used by surveyors in order to measure an angle of inclination or elevation <br />
  9. 9. Line of sight<br /><br />90 line on protractor<br />weight<br />
  10. 10. Uses of Clinometers<br />Indicating pitch and roll of vehicles, sail boats, and aircraft. <br />Monitoring boom angle of cranes and material handlers. <br />Measuring the "look angle" of a satellite antenna towards a satellite.<br />Measuring movements in walls and/or the ground in civil engineering projects <br />Measuring the angle of drilling in well-logging applications. <br />Rollover warning, to alert equipment operator of possible tip over condition <br />Determining the angle of the earth's magnetic field in respect to the horizontal plane.<br />Measuring steepness of a ski slope. (<10o for beginners, 10o-20o "green", 15o-25o "blue", 25o-35o "black", 35o-45o "double black") <br />
  11. 11.  Compass<br />A compass is a navigational survey instrument used for determining the “directions” which is relative to the Earth's magnetic pole<br /><ul><li>A compass can be used to calculate “heading” used with a “sextant” to calculate latitude” and with a “marine chronometer” to calculate “longitude”</li></li></ul><li>GPS<br />GPS<br />
  12. 12. DEVOLPMENT<br />ERATH QUAKE SCENCE<br />PLANS DIRECTION<br /> VEHICALS<br />
  13. 13. ELEMENTS<br />The Space Segment<br />The User Segment<br />The Control Segment<br />
  14. 14. The Space Segment<br />24 Satellite<br />
  15. 15. The User Segment<br />Receiver<br />
  16. 16. The Control Segment<br />Ground station<br />
  17. 17. Principle of Gps<br />Measurement of distance between satellite and receiver<br />Wgs84<br />
  18. 18. Use of Gps in now a days<br />Military use<br />Every day's life<br />
  19. 19. Theodolite<br />Most important application is measuring horizontal and vertical angles<br />Horizontal distances and determine elevations<br />
  20. 20. How to use<br />A theodolite must be mounted on a level tripod or stand from where the user can observe.<br />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.<br />
  21. 21. Prism<br /><ul><li>Prism
  22. 22. Consider the offset,
  23. 23. The thread size,
  24. 24. When working with Total Stations that require a target</li></li></ul><li> That ‘s All Our Presentation<br />Thanks <br />Dear<br />Fellows<br />
