Survey Adjustment Analysis
2012-2013 - GEO2151 - 10 ECTS

Prerequisite(s)

  • GEO1181 Basic Surveying (or GEO1191+GEO1201)
  • GEO2281 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", "GISLINE" and "Leica Geo Office".
- Analysis of Control Networks to develop transformation parameters
- Simple network simulation computations and analysis
