Download Solution PDFConcept:
The equation for closing error and angle fo misclosure is given by,
Where,
e = closing error, θ = angle of misclosure
ΣL = Algebraic sum of latitudes of all lines
ΣD = Algebraic sum of departures of all lines
Important Points
Latitude: It is the length (L) of projection of a line onto the North-South (L cosθ) axis.
Northing → Positive, Southing → Negative
Departure: It is the projection of the line (L) onto the east-west (L sinθ) axis.
Easting → Positive, Westing → Negative
