General description of the script

This script visualizes the Transitions layer from the Global Surface Water dataset according to the official symbology (Table 1). The Transitions layer is derived from a seasonality comparison between the first and last year of the entire time period and visualises changes in the three surface water classes of not water, seasonal, and permanent water.
