Tribhuvan University Institute of Engineering Central Campus, Pulchowk Department of Civil Engineering Survey Instruction Committee

This document appears to be survey observation notes from a field survey containing resection and transferring station measurements. It includes details like the date, observer, instrument used, horizontal angle observations from two sets at each station, and computations to determine coordinates of transferred points based on the observed angles and known control points. Key information observed and computed includes bearings, distances, coordinates of points, and angles between points.

Calculation of coefficient :
K1=1 / (COT (S)-COT (TXC)) = 0.116
K2=1 / (COT (C)-COT (TXS)) = 0.73
K3=1 / (COT (T)-COT (SXC)) = 10.654
TAN (Bearing of XC) = (DEP. OF C-DEP. OF X) / (LAT. OF C-LAT. OF X)
Bearing of XC = 1553703
Bearing of XM11 = 1553703+ 235453
= 1793156
Easting of M11 = Easting of X + L SIN(CXM11)
=626888.175
Northing of M11 = 3063070.085

Bearing of M11M12 = Bearing of XM11+ 1701913- 1800000


=1700555
