Introduction
For more information, please read the block description.
Block type: PROCESSING
This block generates a binary water mask from SPOT and Pléiades images. The block is compatible with the data blocks SPOT 6/7 Reflectance (Download) and Pléiades Reflectance (Download). For processing these images, they first need to be converted to GeoTIFF with the blocks DIMAP -> GeoTIFF Conversion or Pan-sharpening SPOT/Pléiades.
Supported parameters
This block takes no input parameters.
Example usage
Example running the full Waterfinder workflow by using the data block Pléiades Reflectance (Download) and the processing block DIMAP -> GeoTIFF Conversion:
