# 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.
• 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.
