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.
Compatible blocks
Data block | Intermediate processing block | Final processing block |
---|---|---|
Pléiades Reflectance (Download) | DIMAP -> GeoTIFF Conversion | Flood Finder Pléiades/SPOT |
Pléiades Reflectance (Download) | Pan-sharpening | Flood Finder Pléiades/SPOT |
SPOT 6/7 Reflectance (Download) | DIMAP -> GeoTIFF Conversion | Flood Finder Pléiades/SPOT |
SPOT 6/7 Reflectance (Download) | Pan-sharpening | Flood Finder Pléiades/SPOT |
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.
