SURV452 Hydrographic Surveying 2

Fundamentals of acoustics, multibeam sonar systems, motion compensation, side scan sonar methods, LiDAR bathymetry, acoustic positioning, reporting, charting and error analysis, and electronic navigation charts (ENCs).

This paper follows on from the introductory theory of hydrography covered in SURV 322 Hydrographic Surveying. It covers the underlying theoretical framework for acoustics, modern sidescan sonar and multibeam sonars (both beam-forming and sidescan/interferometric systems) in more depth. Methods of vessel motion sensing (heading, pitch and roll) are also covered. This, along with the associated uncertainty theory, leads to modern methods of data processing, analysis and presentation, including the combined uncertainty and bathymetry estimating (CUBE) algorithm and the development of the navigation surface. Calibration of equipment, data connections and reporting is also covered.

Practical and Lab Support: Emily Tidey and Ray McLennan
Paper Structure
This paper covers the following:
  • Data management and interfacing
  • Acoustics and signals
  • Hydrographic equipment and operations: sidescan sonars, multibeam echo sounders, LiDAR, remote sensing, mobilisation and calibrations, geophysics and offshore industrial operations
  • Electronic charting and maritime issues
  • Hydrographic certification and organisations
Teaching Arrangements
Lectures: Three 1-hour lecturers per week

Labs: Eight during semester

Practicals: Four during semester

Blackboard Use: Information and links will be provided on Blackboard as required.

Terms: Hydrographic surveying skills are acquired through practice, which complements the theory gained in lectures and readings. Therefore, students must have attended all of the practical sessions and have submitted all of the assignments.

Internal Assessment: 50%, made of theoretical assignments, practicals and practical reports and a mid-semester test

Exam: 50%, 3 hours
Textbooks
Highly Recommended:
  • IHO Manual of Hydrography
  • IHO Standards for Hydrographic Surveys s44
  • LINZ HYSPEC
All available to download online

Other texts are available in the Science and School of Surveying Libraries and online.
