HB360 Hydrographic Surveying (6ECTS)

The primary objective of this course is to provide advanced insight into marine positioning, depth measurement techniques, and seabed modelling. It aims to deepen students’ understanding of the various sources of error affecting hydrographic data and the levels of accuracy that can be achieved using different instruments and methodologies.

• 1. POSITIONING

a. Classification of positioning systems and project types

b. Working principles of planimetric positioning systems

c. Principles of radio positioning systems

d. Geometric quality of positioning

• 2. BATHYMETRY

a. Types of bathymetric sensors SBE, MBE, side-scan

b. Bathymetric equipment: working principles of acoustic positioning

c. Calibration of equipment

d. Bathymetric project management

1. Explain the working principles of acoustic, optical, and radio positioning

systems, as well as bathymetric sensors, using appropriate scientific terminology.

2. Identify and evaluate the sources of error associated with acoustic, optical, and

radio positioning systems.

3. Construct, apply, and assess error models for planimetric and bathymetric

measurements.

4. Predict the expected accuracy of hydrographic data based on the selected

equipment and methodology.

5. Generate digital seabed models and critically evaluate their quality and

reliability.

6. Produce a well-structured and scientifically justified report on bathymetric data

acquisition or processing.
