+ ### Dataset opening
31
+
32
+ Dataset was compressed using `h5py` and BZip2 from `hdf5plugin`. **WARNING: `hdf5plugin` is necessary to extract data**
33
+
34
  ### Data Instances
35
 
36
+ 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.
37
 
38
  ### Data Fields
39
 
40
+ In each HDF5 file, you can find post-fire, pre-fire images and binary masks. The file is structured in this way:
41
+
42
+ ```bash
43
+ β”œβ”€β”€ foldn
44
+ β”‚ β”œβ”€β”€ uid0
45
+ β”‚ β”‚ β”œβ”€β”€ pre_fire
46
+ β”‚ β”‚ β”œβ”€β”€ post_fire
47
+ β”‚ β”‚ β”œβ”€β”€ mask
48
+ β”‚ β”œβ”€β”€ uid1
49
+ β”‚ β”œβ”€β”€ post_fire
50
+ β”‚ β”œβ”€β”€ mask
51
+ β”‚
52
+ β”œβ”€β”€ foldm
53
+ β”œβ”€β”€ uid2
54
+ β”‚ β”œβ”€β”€ post_fire
55
+ β”‚ β”œβ”€β”€ mask
56
+ β”œβ”€β”€ uid3
57
+ β”œβ”€β”€ pre_fire
58
+ β”œβ”€β”€ post_fire
59
+ β”œβ”€β”€ mask
60
+ ...
61
+ ```
62
+
63
+ where `foldn` and `foldm` are fold names and `uidn` is a unique identifier for the wilfire.
