Introduction to Adjustment Computations GEOM 4090

Geomatics Course

Course details

The emphasis of this course is on the practical applications of adjustment computations. It covers the theory of observational errors, measures of precision and accuracy; propagation law of errors; weights and propagation of weights; confidence region estimation and statistical hypothesis testing; principle of adjustment by traditional methods (Transit, Compass, Crandall’s rules); concepts of least squares adjustment; adjustment of parametric models with constraint equations, pre- and post-adjustment tests to detect blunders, which includes, but not limited to, using computer programming languages/commercial software packages to design 1D, 2D, and 3D survey networks, and analyze curve-fitting and coordinate transformation problems.

Learning Outcomes

Upon successful completion of this course, the student will be able to:

  • Explain the theory of errors, precisions, accuracy and weights, of geospatial measurements.
  • Apply the error and variance-covariance propagation laws to geomatics measurements.
  • Relate the concepts of estimation, probability, hypothesis testing and statistics.
  • Use statistical method to assess the magnitudes of errors in surveying measurements (including the means and variances).
  • Use Transit, Compass and Crandall’s rules to adjust traverse networks.
  • Discuss the assumptions, concept, advantages, disadvantages and applications of least squares adjustment.
  • Formulate parametric model equations of survey measurements for least squares adjustment.
  • Apply the principle of parametric least squares adjustment to adjust simple survey network measurements.
  • Solve practical geomatics problems, including 1D, 2D and 3D survey networks adjustment and pre-analyses, curve-fitting, and coordinate transformations using a commercial least squares adjustment package.
  • Perform post adjustment global and local tests to detect outliers in measurements and to evaluate quality of adjustment computations using commercial software.
  • Adjust simple survey measurements using a computer programming language.
