Overview

Complete the two challenge tasks in order. Collaborate with colleagues and your instructors. Happy Coding!

Task 1: Create Normalized Difference Vegetation Index

Create a Normalized Difference Vegetation Index (NDVI) using the Landsat 8 dataset for a period from January 2020 to June 2022 for a specific region of Trinidad and Tobago.

Hint 1: There are good example scripts in the ‘Examples’ folder of the Scripts panel. look for existent scripts that already have done something similar.

Hint 2: Make use of the Cloud-Based Remote Sensing with Google Earth Engine: Fundamentals and Applications book (https://eefabook.org) to find help.

Task 2: Export then Import the NDWI image

Export the NDVI image at a resolution of 100 meters in the Coordinate Reference System ‘EPSG:3857’. Export it to an EE asset, then re-import the uploaded EE image, and display it in the code editor.

*Hint: In the Docs tab, look for the correct function to to export your NDVI product to an EE asset.
