Welcome to the Google Earth Engine tutorial for working with the global surface water (GSW)
dataset. This dataset is described in the Nature letter
High-resolution mapping of global surface water and its long-term changes.
This tutorial provides examples of how to use Earth Engine to visualize data layers
available in the GSW dataset, and presents some typical visualizations and analyses.
The tutorial is broken up into sections. Within each section, code will be built up
gradually with short code snippets and explanatory text. At the end of each section, the
complete working script will be presented.
The GSW data described in this tutorial were produced under the
Copernicus Programme and
are provided free of charge, without restriction of use. For the full license information
see the Copernicus Regulation.
If you are using the data as a layer in a published map, please include the following
