This script calculates the Normalised Difference Vegetation Index (NDVI) using Sentinel 2 data for an Area of Interest given by a geojson polygon. The data is obtained and processed using the Google Earth Engine API. It returns the absolute and relative vegetation area and maps the results for five time frames. Clouds are masked and the cloudy area is returned in the email.

The script checks for new data and compares the latest available data it to the latest results stored locally. If new data is available an email is generated with the results and maps. A crontab command allows to run this daily and provide the email results if new data is published.
