### Dataset Summary |
|
|
|
This dataset contains images from Sentinel-2 satellites taken before and after a wildfire. |
|
The ground truth masks are provided by the California Department of Forestry and Fire Protection and they are mapped on the images. |
|
|
|
### Supported Tasks |
|
|
|
The dataset is designed to do binary semantic segmentation of burned vs unburned areas. |
|
|
|
## Dataset Structure |
|
|
|
### Dataset opening |
|
|
|
Dataset was compressed using `h5py` and BZip2 from `hdf5plugin`. **WARNING: `hdf5plugin` is necessary to extract data** |
|
|
|
### Data Instances |
|
|
|
Each matrix has a shape of 5490x5490xC, where C is 12 for pre-fire and post-fire images, while it is 0 for binary masks. |
|
|
|
### Data Fields |
|
|
|
In each HDF5 file, you can find post-fire, pre-fire images and binary masks. The file is structured in this way: |
|
|
|
```bash |
|
├── foldn |
|
│ ├── uid0 |
|
│ │ ├── pre_fire |
|
│ │ ├── post_fire |
|
│ │ ├── mask |
|
│ ├── uid1 |
|
│ ├── post_fire |
|
│ ├── mask |
|
│ |
|
├── foldm |
|
├── uid2 |
|
│ ├── post_fire |
|
│ ├── mask |
|
├── uid3 |
|
├── pre_fire |
|
├── post_fire |
|
├── mask |
|
... |
|
``` |
|
|
|
where `foldn` and `foldm` are fold names and `uidn` is a unique identifier for the wilfire. |
|
|
|
### Data Splits |
|
|
|
There are 5 random splits whose names are: 0, 1, 2, 3 and 4. |
