TRAVERSE CLOSE ASSIGNMENT

A closed traverse was run from A to B, then C and back to A, with radiations made at B and C to Y and X respectively.
The diagram below showsthe reduced observations made at A and B and the field notes recorded when the theodolite was set up at C. When the distances were observed at C, the tape was placed on evenly sloping ground and the appropriate vertical angle observed.

Reduce the field notes made at C, in the spaces on the booking sheet.

Calculate the angular misclose and the adjusted bearings of all the traverse lines and radiations.

Angular Misclose of traverse

Bearing of B-C Bearing of C-A

Bearing of B-Y Bearing of C-X

Traverse Close

Complete the traverse table to find the linear misclose, proportional accuracy of the traverse, the coordinates of all points and the bearing and distance of the line X-Y.

	Adjusted	Horiz.	D	E	D	N	CO-ORD	INATES
LINE	Bearing	Dist	E (+)	W (-)	N (+)	S(-)	E	N	PT.
