Syllabus for Advanced Surveying

Unit I: Field Astronomy

Definitions of astronomical terms, coordinate systems for locating heavenly bodies. Geographic, Geodetic, Geocentric, Cartesian, Local and Projected coordinates for earth resources mapping. Convergence of meridian, parallel of latitude, shortest distance between two points on the earth, determination of latitude and longitude.

Unit II: Basics of Geodesy

Introduction to Spherical Trigonometry and Spherical Coordinates; History and Development of Geodesy, Geodetic, Datums and Control; Networks; Understanding the Geometry of Reference Ellipsoid , Reference Coordinate Systems, Coordinate or datum Conversion, Lines (curves) on the Ellipsoid, Normal sections and geodetic lines, Radii of curvature and calculation of lengths of lines; Direction of lines on the ellipsoid

Unit III: Theory of errors and Adjustment of survey measurements

Sources of errors; types of error; accuracy and precision, propagation ofvariance/covariance and adjustment of errors using observation equation and condition equation approach (approximate and matrix-based solution) with example on adjustment of level nets, traverse, triangulation figures.

Unit IV: Triangulation and Trilateration
