Session 5 Quiz and Solution

In Session 5, you looked at the framework of a case study. Building on elements from previous sessions — such as loading data, calculating an index, and plotting results — you used a new index, the Enhanced Vegetation Index (EVI), to show differences over time. The first half of EVI data was compared to the second half, and mapped to show relative increase or decrease.


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.

This quiz does not require a notebook to solve. However, you may find the EVI vegetation change detection notebook useful as a reference. If you would like to confirm that your vegetation change 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.
