- 1. The introduction and applications of TOTAL STATION (Leica TS02/06/09) LUONG BAO BINH Dept. of Geomatics Engineering University of Technology, HCMC, VN
- 2. Contents• Introduction – Fundamental measurements – Why is the total station? – Modern technologies• Basic functions – Target offset – Height transfer – Hidden point – Check tie 2
- 3. Contents (cont.)• Applications – Surveying & Traverse – Stake out – Free station – Reference line & Reference arc – Tie distance – Area and volume – Remote height – Coordinate geometry calculations – Road 2D and 3D 3
- 4. Fundamental measurementsAngle with theodolites Leveling with levels Distance with tape or EDMShould we combine them in an instrument? 4
- 5. Why is the total station?• Problem: in practice, not only individual measurements but also the combinations of measurements and the calculations are required for many tasks.• Solution: the total stationElectronic Total + EDM + Firmware =theodolite station 5
- 6. Advantages of total station• All-in-one instrument for multi-task• Reliable and highly accurate• Integrated applications available for many common tasks• Automatic and easy in data storage and transfer• A complete procedure from surveying to map plotting is available with appropriate softwares 6
- 7. Accuracy and range Prism mode 7
- 8. Accuracy and range Non-prism mode 8
- 9. Modern technologies• Reflectorless (non-prism mode)• Integrated GPS (smart station)• Auto tracking (robotic) 9
- 10. Integrated GPS 10
- 11. Integrated GPS 11
- 12. Basic functions• Target offset• Height transfer• Hidden point• Check tie 12
- 13. Target offsetDetermines the target point P2 from:_ the offset point P1 and_ two distances: traverse offset and length offset 13
- 14. Cylinder offsetDetermines the center P1and radius R from_ three points on the border 14
- 15. Height transferDetermines the instrument height at P0 from:_ the point(s) Pi with known height(s) 15
- 16. Hidden pointDetermines the hidden point P1 from:_ two points 1 and 2, and_ distances d1 & d2 on the rod 16
- 17. Check tieCalculates from 2 measured points P1 & P2::_ slope and horizontal distance_ azimuth_ grade_ height difference_ coordinates diference 17
- 18. Applications• Traverse and Surveying• Stake out• Free station• Reference line & Reference arc• Area and volume• Remote height• Coordinate geometry calculations• Road 2D & 3D 18
- 19. Traverse• Helmet transformation• Adjustment• Checking point and tolerance• Start the traverse with or without known backsight• Measure sideshot 19
- 20. Traverse 20
- 21. Traverse 21
- 22. Stake outPolar mode Orthogonal mode Cartesian mode 22
- 23. Free stationDetermines the instrument position P0 from at least 2 known points Pi 23
- 24. Reference line• Reference Line is an application that facilitates the easy stake out or checking of lines, for example, for buildings, sections of road, or simple excavations. It allows the user to define a reference line and then complete the following tasks with respect to that line: – Line & offset – Point & Grid stake out – Line segmentation stake out 24
- 25. Base lineBase line is defined by 2 pointswhich can be:_ measured, or_ entered / selected from memory 25
- 26. Reference lineReference line is created by:_ parallel / longitudinal offset_ rotatedfrom base line / base point 26
- 27. Line & offset to calculate: _ offsets _ height difference of target point relative to ref. line 27
- 28. Stake outGrid stake out Point stake out 28
- 29. Line segmentation stake out 29
- 30. Reference arc• Line & offset• Stake out: – Point – Arc – Chord – Angle 30
- 31. Reference arc 31
- 32. Line & offset 32
- 33. Stake out (point & angle) 33
- 34. Stake out (arc & chord) 34
- 35. Tie distancePolynomial method 35
- 36. Tie distanceRadial method 36
- 37. Area 37
- 38. Volume 38
- 39. Remote height to compute points (without prism) directly above the base prism 39
- 40. Geometry calculations• Inverse and Traverse• Intersection• Offset• Extension 40
- 41. Inverseto calculate:_ distance_ direction_ height difference_ gradebetween 2 known points 41
- 42. Traverse to calculate the position of a new point using: _ distance _ bearing from a known points 42
- 43. IntersectionsBearing-Bearing Bearing-Distance (2 lines) (a line & a circle) 43
- 44. Intersections By PointsDistance-Distance (4 points on 2 lines) (2 circles) 44
- 45. OffsetsDistance-offset Set point Plane offset 45
- 46. Extensionto calculate the extended point from a known base line 46
- 47. Road 2D 47
- 48. Road 3DQuadratic Parabola 48
