In this tutorial, I will present how to calculate NDVI of Sentinel 2 in Google Earth Engine.
The Normalized Difference Vegetation Index (NDVI) measures the difference between near-infrared (which vegetation strongly reflects) and red light (which vegetation absorbs) to quantify vegetation. NDVI always ranges from -1 to +1. If there are no green leaves, the value is zero. A zero denotes no vegetation, whereas a value close to +1 (0.8-0.9) suggests the highest density of green leaves conceivable. However, the land cover type does not have its specific limit of NDVI values.
The formula for calculating NDVI is as follows:

NDVI = (NIR — RED)/(NIR + RED)

NIR – reflection in the near-infrared spectrum
RED – reflection in the red range of the spectrum

The output range of NDVI calculation typically varies from -1.0 to 1.0.

bro, how you fix the clouds when you take an image? I try to do this method in Ecuador but in my country I have so many clouds, please can you add that part for the same case to calculate the NDVI, PLEASE.
