Flood Finder Pléiades/SPOT

Creates a binary flood mask for Pléiades/SPOT Reflectance blocks.


Introduction

The Flood Finder processing block generates a binary flood mask for Pléiades and SPOT images.

Technical information

Algorithm description

The Flood Finder computes the difference in flood cover between 2 or more images and generates a binary flood mask. If using image IDs, the flooded image should be the first ID in the JSON parameter configuration. It is highly recommended to use the geometry filter contains and ensure perfect spatial overlap.

Output files

This block generates outputs in 8-bit GeoTIFF format.

Geographic coverage

The geographic coverage is global.

How it works

This block has no configurable JSON parameters.

Limitations

This algorithm works for more than 2 images.
