Session 6 Quiz and Solution

In Session 6, you used the case study framework to construct an analysis on water extent. This involved using the Water Observations from Space (WOfS) dataset. The WOfS dataset identifies water pixels, which you used to calculate the area of water. The water extent was plotted next to an RGB map of the same area.


If you would like to be awarded a certificate of achievement at the end of the course, we ask that you complete the quiz. You will need to supply your email address to progress towards the certificate. After you complete the quiz, you can check if your answers were correct by pressing the View Accuracy button.

If you have successfully passed all six assessment quizzes, you will be awarded a Certificate of Completion. If you have any questions about the Certificate of Completion, please see the FAQ.

The quiz will ask you to use the notebook you developed for this session’s exercise on plotting water extent using WOfS data. If you would like to confirm that your notebook works as expected, you can check it against the solution notebook provided below.


The solution notebook below does not contain the answer to the quiz. Use it to check that you implemented the exercise correctly, then use your exercise notebook to help with the quiz. Accessing the solution notebook will not affect your progression towards the certificate.
