# Survey Adjustment Analysis - GEO2151 - 10 ECTS

## Prerequisite(s)

GEO1141 Land Surveying Instruments and Computations

## On the basis of

GEO2241 - Practical Land Surveying

## Expected learning outcomes

On completion of this course, students will have acquired a good practical understanding of the processes involved in adjusting networks of observations of different types using the Least Squares Method.

Students will be able to:
- Carry out a Least Squares Adjustment of a set of observations
- Analyse the quality of the observations, of the available data, and of the results
- Use the standard Norwegian network adjustment software systems
- Use standard GPS-based network adjustment software systems
- Deliver appropriate project reports in accordance with current professional standards.

## Topic(s)

- Theory of Adjustment by the method of Least Squares
- Formation of Observation Equations in different situations
- Weighting of Observation Equations
- Techniques for the solution of large sets of linear equation, including the use of simple matrix algebra
- Detection of observational errors in control networks
- Statistics, reliability testing, quality control and analysis
- Reporting
- Land survey software systems GEMINI" and GISLINE".
- Analysis of Control Networks to develop transformation parameters
- Simple network simulation computations and analysis
