# Wildfires - CEMS

The dataset includes annotations for burned area delineation and land cover segmentation, with a focus on European soil.
The dataset is curated from various sources, including the Copernicus European Monitoring System (EMS) and Sentinel-2 feeds.

## Dataset Structure

The main dataset used in the paper comprises the following inputs:

| Suffix  | Data Type          | Description                                                                               | Format                   |
|---------|--------------------|-------------------------------------------------------------------------------------------|--------------------------|
| S2L2A   | Sentinel-2 Image   | L2A data with 12 channels in reflectance/10k format                                       | GeoTIFF (.tif)           |
| DEL     | Delineation Map    | Binary map indicating burned areas as uint8 values (0 or 1)                               | GeoTIFF (.tif)           |
| GRA     | Grading Map        | Grading information (if available) with uint8 values ranging from 0 to 4                  | GeoTIFF (.tif)           |
| ESA_LC  | Land Cover Map     | ESA WorldCover 2020 land cover classes as uint8 values                                    | GeoTIFF (.tif)           |
| CM      | Cloud Cover Map    | Cloud cover mask, uint8 values generated using CloudSen12 (0 or 1)                        | GeoTIFF (.tif)           |

Additionally, the dataset also contains two land cover variants, the ESRI Annual Land Cover (9 categories) and the static variant (10 categories), not used in this study.
The dataset already provides a `train` / `val` / `test` split for convenience, however the inner structure of each group is the same.
The folders are structured as follows:

```

### Source Data

- Activations are directly derived from Copernicus EMS (CEMS): [https://emergency.copernicus.eu/mapping/list-of-activations-rapid](https://emergency.copernicus.eu/mapping/list-of-activations-rapid)
- Sentinel-2 and LC images are downloaded from Microsoft Planetary Computer, using the AoI provided by CEMS.
- DEL and GRA maps represent the rasterized version of the delineation/grading products provided by the Copernicus service.
