Waterfinder

Generates a binary water mask from SPOT and Pléiades images.


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: Pleiades Download block, DIMAP -> GeoTIFF Conversion, and UP42 Waterfinder:
