Tacheometry-Surveying-

Explain Field Procedure in Tacheometry Traversing.

  • Reconnaissance
  • Establishment of tacheometric closed traverse as per field requirement ensuring each instrument station should command a wide area. If the area is too large,link traverse and addition of triangles may also be prederred.


  • A tacheometer is set up at the starting station. It is centered and levelled accurately. Height of instruments is Measured.
  • The instrument is oriented with reference to any predetermined station (BS) by taking it's bearing.Horizontal angles of all nearby details are recorded in a field book. Index map and reference sketches are also prepared in field.
