I'm starting to play with Google Earth Engine. Following https://docs.google.com/document/d/1mNIRB90jwLuASO1JYas1kuOXCLbOoy1Z4NlV1qIXM10/edit# I managet to put together this https://code.earthengine.google.com/625b11fca42309bd7f37159434cd21cf, which generates a time series plot of NDVI. I kind of understand it until the plot.
After that it sets
dependent variables. And computes the
trend which is added to the map.
May I ask for help on how to interpret this? What red means?
