Google Earth Engine: Change detection analysis using near real-time Dynamic Global Land cover data
In this tutorial I will show how to access the Dymanic World Landcover dataset and further how to do the change detection analysis using the data
Dynamic World is a near realtime 10m resolution global land use land cover dataset based on Sentinel-2 satellite Images, produced using deep learning, freely available and openly licensed. It is the result of a partnership between Google and the World Resources Institute, to produce a dynamic dataset of the physical material on the surface of the Earth. Dynamic World is intended to be used as a data product for users to add custom rules with which to assign final class values, producing derivative land cover maps.
