SURV322 Hydrographic Surveying

An introduction to the hydrographic industry, hydrographic specifications, position fixing, datums, tides, instrumentation, data capture, sounding reduction, and plotting.

This introduction to hydrography is designed to provide a broad overview of the many facets of hydrographic surveying. Student time is split between lectures, fieldwork in small boats on Otago Harbour and processing and analysis time spent in the computer laboratory. By the end of the paper students are required to be able to produce a professional report and 'field sheet' and to support their work with an organised body of original survey data.

This paper can be taken as a standalone elective in a land surveying degree, providing the skills necessary to assist in a simple harbour or river survey. It can also be part of a more extensive programme concentrating on hydrographic surveying.

Textbooks
Highly recommended:
  • IHO Manual of Hydrography
  • LINZ HYSPEC
Both available to download online

Other texts are available in the Science and School of Surveying Libraries and online.
Paper Structure
The paper covers the following:
  • Positioning and datums
  • Tides, oceanography and sampling
  • Hydrographic equipment: acoustics and singlebeam echo sounders
  • Hydrographic operations: charting - acquisition, processing, accuracy, quality control and reporting
  • Other hydrographic equipment: sidescan sonar, multibeam echo sounders, LiDAR, ROV and AUV
  • Other hydrographic operations: ports and coastal zone, offshore industrial surveys
Teaching Arrangements
Lectures: Three 1-hour lectures per week

Labs: Six during the semester

Practicals: Six 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 or lab sessions and have submitted all of the assignments to gain terms.

Internal Assessment: 70%, made of theoretical assignments, practicals and practical reports and a mid-semester test.

Exam: 30%, 2 hours
Graduate Attributes Emphasised
Global perspective, Interdisciplinary perspective, Communication, Environmental literacy, Information literacy, Self-motivation, Teamwork.

Learning Outcomes
The goals of the paper are
  • To familiarise the student with international/national hydrographic practice and context, in particular for the field of nautical charting
  • To gain an awareness of other fields of hydrographic surveying, including seismic operations, offshore construction, port management and coastal engineering, environmental, archaeology, inland waters and military
  • To understand the basics of tidal theory
  • To understand the concepts of vertical and horizontal datums in hydrography
  • To understand the use of hydrographic instruments (including calibration and operation): sextant, singlebeam echo sounder, sidescan sonar, tide gauge, DGNSS, RTK GNSS
  • To develop practical hydrographic surveying skills and seamanship, including manoeuvring a boat less than 6 metres in length
  • To undertake simple singlebeam hydrographic surveys and to present the results in a standard professional format
  • To develop an introductory understanding of the measurement tasks in hydrography, with particular attention to accuracy and error management
