Option stage terrain (hydro-océano) (ENSTA Bretagne)


Student perform a complete survey of a lake, river or bay, from system installation, set-up, operations, data processing, and chart production on various subjects, each subject being elective, among six possible topics.

Use of CTD, ADCP, Lidar and various other sensors, then data processing and interpretation, are a central part of the activity of this teaching unit. Students

Teaching and learning methods

This project aims at student autonomy and self management. Teams of 3-6 students have dedicated assignments during the Semester with also self-study.

Personal work


Pré-requis nécessaires

This survey will take place early in the academic year, so that few pre-requisites can be asked; ease with computer language is most useful; interest for in situ measurements is required


Software used

Qinsy, Caris/HIPS & SIPS, Caris/57-Composer, Caris/BaseEditor, Seanet, GRASS, GNSS studio, MATLAB, Python, TELEMAC


Each student will deepen his knowledge in the topics involved by the project he has chosen

  • Sediment mapping;

  • GNSS

  • Mobile terrestrial LiDAR survey;

  • Bathymetric survey and data analysis;

  • Geodesy and land surveying;

  • Oceanographic surveys and coastal modelling;

They will also increase their understanding of the crossed relationships between the fields of geodesy, hydrography and oceanography. Students will improve their ability to work in international team. In addition, one of the main objectives of this course is to make the students as independent as possible from any academic supervision.

The project takes place on the Bay of Brest, which is an opportunity to enhance the students experience in coastal oceanography, bathymetry and data georeferencing with respect to geodetic frames and references used in terrestrial mapping.
