LEARNING OUTCOMES
The aim of this course is the achievement of theoretical background and practical knowledge of the planning, establishment and measure of surveying networks, the pre-processing of the observations, the adjustment and the testing of the horizontal and vertical control networks.
Basic course goals:
- Planning of surveying networks based on quality criteria
- Establish and measure surveying networks
- Network development based on specific methodologies
- Optimal combination of data and accurate coordinate estimation
- Accuracy assessments
- Statistical testing of observations
- Adjustment validation
- Final adjustment in GGRS87 – Measurement reductions
General Competences
- Search for, analysis and synthesis of data and information,
- with the use of the necessary technology
- Decision-making
- Working independently
- Production of free, creative and inductive thinking
