As a new person to this type of work, this course is very useful in providing an overall picture of the value in generating data by survey to providing meaningful information to the public with the various types of maps/charts.

I think the things I learnt here were not necessarily practical with regard to hydrography but more historical. I have industry experience and hoped the course would provide more theoretical information

I enjoyed the interactive aspects of this course. I would recommend more questions per section.

Give more clues as to what information to retain when given so much data.

Good lesson, it has a little more emphasis on charts than hydro collection. But it does give an overview of what goes into collection and how that varies from regular bathy collection. I also enjoyed the history behind the science. I would say this is a good lesson to take if you are interested in learning an overview of what hydro is.
