About this course

Content

- Introduction/repetition of linear algebra
- Least squares adjustment (the parameter method)
- Development og error equations for  leveoobservatio types levelling, total station, GNSS baseline, GNSS point observation
- Weight functions for the same observation types as above
- The theory behind multiple t-test, Chi-square test, F-test, confidence intervals, inner and outer reliability
- Adjustment computations by means of the most common Norwegian softwares and corresponding Norwegian standards
- Additional parameters in least squares adjustment (scale, rotation and deflection of the vertical)
- Simulation and planning of reference point measurement

Learning outcomes

In the end of this course, the student should be able to:

- Use the most common Norwegian sotwares for adjustment computations for levelling-, GNSS- and total station observations
- Understand an explain relevant Norwegian standards for adjustment computations and corresponding documentation
- Do adjustment in practice on a given dataset
- Assess the quality of observations, background data and the outcoming results of an adjustment
- Deliver professional reports of adjustment computations
