Specification
Inundation classes (INU-CLASSES)
Inundation derived from Sentinel-1 data. Based on open water detection in combination with change detection and thresholding.
- INU-CLASSES:
Classified files using classes 0-6 based on the following input maps as a first step:
- W:
Water detected using histogram method (0, 1)
- V:
Change detection in VV (0,1,2)
- VH:
Change detection in VH (0,1,2)
In the second step these maps are combined into one final maps using the following lookup table:
- 0:
VV = 0, VH = 0 W = 0 - no color
- 1:
W = 0, VV >=1, VH >= 0 - white
- 2:
W = 1, VV = 1, VH = 0 - blue
- 3:
W = 1, VV = 2, VH = 0 - blue
- 4:
W = 1, VV = 1, VH >= 1 - blue
- 5:
W = 1, VV = 2, VH = 1 - blue
- 6:
W = 1, VV = 2, VH = 2 - dark blue

Inundation RGB (INU-RGB)
Inundation is derived from Sentinel-1 data using an approach based on histogram matching of know open water and grassland histograms in combination with change detection and thresholding.
- INU-RGB:
A false colour file in which the Red channel is taken from the VV polarisation and the Green and Blue Channel the VH polarisation.

Inundation rolling mean (INU-RM)
Inundation is derived from Sentinel-1 data using an approach based on histogram matching of know open water and grassland histograms in combination with change detection and thresholding.
- rolling mean of VV and VH:
30 image rolling mean of the VV an VH images used as a base for the change detection.
