  The Fundamentals of Hydrographic Survey course provided a comprehensive understanding of the essential principles and technologies used in marine surveying. The lessons were well-structured, covering key topics such as multibeam and side-scan sonar, bathymetric LiDAR, and satellite imaging. I particularly appreciated how theoretical concepts were connected to practical applications, making it easier to understand real-world survey operations. The assessments were useful in reinforcing key ideas, and the course helped me build confidence in interpreting hydrographic data. Overall, it was an informative and engaging experience that strengthened my knowledge of hydrography and marine mapping.

  As a surveyor and MSc Geoinformatics student, I found the Fundamentals of Hydrographic Survey course by IHO very informative. It provided a solid understanding of hydrographic survey principles, modern sonar systems, GNSS applications, and data processing techniques, with practical examples connecting theory to real-world applications. Some videos were repetitive and slightly mixed up, and some quiz questions appeared in different languages, which was confusing. I hope these issues are corrected in future editions. Despite this, the course significantly enhanced my skills for professional hydrographic and geospatial work.
  
  Thank you, IHO, for providing this valuable learning opportunity!

  The IHO Fundamentals of Hydrographic Survey course provides an excellent introduction to hydrography, sonar, and LiDAR technologies. As a Geomatics Engineer, I found it particularly valuable for understanding how these surveying techniques integrate with geospatial data and marine mapping. The course materials are clear and easy to follow, and completing it provided a strong foundation for professional development in hydrographic surveying. I highly recommend it to anyone in the field of geomatics or related disciplines.

  Hello everybody!
  I got my certificate of completion finaly. What have I done to get it - I've passed all the exams on all the languages (yes, all 4 exams).
  And if you find the 99% the course progress after you wathed all the videos and passed the exam just accurately check if really watched all the videos. It is more likely you missed a couple of lessons;)

  does anyone have an answer to this question?
  I've answered all sorts of things but it's still wrong
  
  When installing a multi-beam on a survey vessel, the distance and angle between each survey instrument must be measured to calculate the water depth at a valid location and depth and to integrate the data. What is this called?
