Topics
In tacheometry we details discuss about tacheometry, instrument used in tacheometry, tacheometer, stadia rod, stadia system, fixed hair system, movable hair system, tangential system, subtense bar system, theory of tacheometer, distance and elevation through tacheometer when a staff is vertical & staff is perpendicular to line of sight.
In liner measurements,we details discuss about procedure in chain surveying,basic definition of chain surveying- main station, tie station, main survey line, tie line/ subsidiary line, base line, check line/ proof line, offset, chainage, well conditioned triangle.Correction in chaining,limiting length of offsets.
