About
About the course
Course content
- Error theory and error propagation
- Weights of observations
- Least squares method; mathematical fundaments
- Adjustment calculation using least squares method
- Developing observation equations (from leveling, angle- and distance observations)
- Adjustment of level nets (coding)
- Adjustment of resection (free stationing) (coding)
- Adjustment of networks (off the shelf software)
- Blunder detection, goodness of fit test, internal reliability, external reliability and the related Norwegian standards
- Network analyses (off the shelf software)
- Coordinate transformations (coding)
Learning outcome
The candidate:
- has fundamental knowledge of adjustment and analysis of surveying data from methods such as leveling, total station, and GNSS, using the least squares method.
- possesses the necessary knowledge to use national and international software for adjustment calculations and analyzing surveying data.
- can explain relevant standards in surveying and prepare documentation in accordance with them.
- can apply their knowledge to design, measure, and calculate a control point network that meets industry standards for quality and reliability.
- has sufficient knowledge of error theory, blunder detection, testing the quality of known input data, and reliability analysis to ensure accurate results in surveying projects.
Learning methods and activities
- Lectures
- Project work
- Supervision
The course can be given as a guided self-study if less than 6 students are registered.
The course includes mandatory requirements that require in-person attendance at the Gjøvik campus. Students in online study programs should plan for two on-campus meetings in Gjøvik, each lasting up to three days.
Further on evaluation
A retake oral exam will be held in August. In case of failure, the assignments must be completed again when the course is retaken. The portfolio consists of 3 assignments to be turned in. Some will be handed in as groupwork, while others as individual work. All assignments must be passed. 40% of the course's grade will be based on an overall evaluation of the submitted assignments. Assignments that are rejected will be given a deadline to make a deferred resubmission upon petition to the course coordinator. Any appeals concerning the grading of the assignment will only apply to the 40% of the overall course grade constituted by the assignments.
