Whole circle bearing formula

Also, latitude and departure are explained. Prismatic compass and surveyors compass major differences are also explained along with . The definition of the whole circle bearing along with the measuring formula and example is discussed below. Whole Circle Bearing (WCB), Reduced(Quadrantal) Bearing System.

Bearing are always taken from magnetic north or south whichever is nearer.

Its value varies from zero to 360°, increasing in clockwise direction.

Bearings are always taken in clockwise direction.

Zero is north direction, 90° is east, 180° is south and 270° is west (Ref. Fig. 1). This type of bearing is used in prismatic compass.

The whole circle bearing (W.C.B) of the line OA is 52° and that of line OB is 208°. In this construction video tutorial, some useful tips and formulas are provided for converting whole circle bearings (WCB) into reduced bearings (RB). The video is very useful for land surveyors. For the purpose of this exercise the learner should draw out the geometry of each station and ensure that the correct geometrical relationships are established.

The purpose of the traverse is to establish the co-ordinates of each station . NOTE: Might not be working on Android 5. A bearing is an measurement of direction between two points. There are two types of bearing. B - Reduced Bearing or Quadrant Bearing. Whole circle bearing : the local north is rotated clockwise to the direction of the target.

The angle which is swept is called the whole circle bearing. WCB of reverse direction: Transferring WCBs: WCBAB is known, a is measure how much is WCBAC? Convert whole circle bearing to reduced bearings and vice versa and find internal angles from bearings. The correct quadrant can be found by inspection of the relative positions of the coordinated points. Explain the adjustments, upkeep . Conversion of reduced bearing (RB) to whole circle bearing (WCB) and vice versa.

The RB of any line can be converted to its equivalent RB as shown in Table 19. How to - calculate interior and exterior angles of polygons - Duration: 8:52. Surveying: Traverse - Duration: 24:00.
