Description
A processing block that computes the difference in flood cover between 2 or more images and generates a binary flood mask.
See this block on the marketplace.
How it works
This block has no configurable JSON parameters.
If using image IDs, the flooded image should be the first ID in the JSON parameter configuration. Use the geometry filter contains to ensure perfect spatial overlap.
Compatibility
Data blocks
The Pléiades and SPOT data blocks need to first be converted to GeoTIFF with the processing blocks DIMAP → GeoTIFF Conversion or Pansharpening.
Catalog datasets
Use in combination with Processing from Storage.
