  ## WorldFloods Φsat-2 dataset
19
 
20
- The **WorldFloods Φsat-2 dataset** is an adaptation of the [WorldFloodsv2 dataset](https://huggingface.co/datasets/isp-uv-es/WorldFloodsv2) created with the purpose of simulating a Φsat-2-like dataset for traning Foundation Models for this mission.
21
  Φsat-2 images were simulated using the code in the [OrbitalAI Challenge](https://github.com/AI4EO/orbitalAI). For storing the dataset, we followed the [PhiSatNet repo](https://github.com/sirbastiano/PhiSatNet) Data Specification Format.
22
- Since the WorldFloodsv2 dataset contains full flood scenes rather than small patches, we created non-overlapping Train and Validation patches of size 512x512 pixels from the simulated images, and only stored patches with less than 20% cloud cover, as we do on the fly to train the flood segmentation models described in the paper [Global flood extent segmentation in optical satellite images](https://www.nature.com/articles/s41598-023-47595-7).
23
  For Test samples, however, we kept the full scenes as this allows a better evaluation of flood detection models.
24
  The total size of the dataset is 389 GB.
