Now that we have learned how to calculate the NDVI and NBR in different ways for different sensors, let us have a look on how to monitor them over longer time series, create charts for visualization and calculate areas.

To do so, we are going to have a look at some code that lets us derive the NDVI and NBR of any Area of Interest we want from Landsat 8 data, beginning at the moment the sensor started transmitting.

Please keep adding up the code snippets on the following pages for NDVI and NBR respectively, as they build up on each other. NDVI and NBR can be handled seperately, though. Also, please pay attention that the maps are not displayed by default to save processing time! To view the maps, simply toggle them on in the Layer-tab of the Map-Panel.

Supporting videos can be found for the NDVI code. Everything shown can be handled the same way for the NBR, as it is basically the same code. It is advised to first work through the code, then watch the videos, as you will get a deeper understanding of the handled data and process steps. The videos are mainly focused on how to navigate the results.

In case generating charts or calculating class areas produces an error, simply run the script again to fix it.
