Contouring & Measurement of Area and Volume
Introduction, Measurement of Area: Computation of Area of Geometrical Figures- Rectangle, Square, Triangle, Circle, Parallelogram, Trapezoid, Trapezium, Oblique Triangle, Area of a Segment, Regular Polygon. Computation of Area of Irregular Shape– Mid Ordinate Rule, Average Offset Rule, Trapezoidal Rule, Simpson’s One Third Rule. Measurement Of Volume : Computation of Volume of Irregular Shape– Trapezoidal Rule / End Area Method, Prismoidal / Simpson’s Rule
Topics
In measurement of area and volume, we details discuss about mid ordinate rule, average offset rule, trapezoidal rule, simpson's rule for measurement of area & trapezoidal rule / end area method, prismoidal / simpson’s rule for measurement of volume.
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.
