  • 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.
    This data is available under a Creative Commons BY-4.0 license and requires the following attribution: This dataset is produced for the Dynamic World Project by Google in partnership with National Geographic Society and the World Resources Institute.

    Zoom to any part of area of interest hillshade layer will load...

    Hello. Can we identify the deforestation area by this methodology? If yes can you share the conditional statement for this logic?

    Great Tutorials. Thanks. How can we export the LULC layer with the classified code as unique pixel value - if you please reply, that would be very helpful. Thanks

    What is the timeline of this dataset?

    Probability Hillshade: Tile error: Output of image computation is too large (9 bands for 198723105 pixels = 13645.2 MiB > 80.0 MiB).
    If this is a reduction, try specifying a larger 'tileScale' parameter.
    Kindly fixed this Error in LULC Code......
