This repository contains the trained models of the publication:
Portalés-Julià, Enrique and Mateo-García, Gonzalo and Gómez-Chova, Luis, Understanding Flood Detection Models Across Sentinel-1 and Sentinel-2 Modalities and Benchmark Datasets., published in Remote Sensing of Environment.
We include the trained models:
- sm_unet_s2 Model trained on the Sentinel-2 L1C bands
["B02", "B03", "B04", "B08", "B11", "B12"]from the S1S2Water and WorldFloods datasets. - sm_unet_s1 Model trained on the Sentinel-1 GRD data (
[VV, VH]channels) from the S1S2Water and Kuro Siwo datasets. - mm_unet_s1s2 Dual stream with modality token model, trained on the S1S2Water (Sentinel-1 GRD and Sentinel-2 L1C data), WorldFloods (Sentinel-2 L1C) and Kuro Siwo Sentinel-1 GRD data.
In order to run any of these models in Sentinel-1 and/or Sentinel-2 data see the tutorial Run model in the udl4fl package.
