## Dataset Summary
|
| 10 |
+
|
| 11 |
+
This dataset contains burn scar intensity data and Harmonized Landsat and Sentinel-2 (HLS) images for burn scar analysis across various time frames: pre-burn, during-burn, and post-burn.
|
| 12 |
+
Each file provides spatial information on burn scar intensity and top-of-atmosphere (TOA) reflectance values.
|
| 13 |
+
|
| 14 |
+
The dataset includes:
|
| 15 |
+
- **BS_files_raw.csv**: The complete set of burn scar intensity data without filtering.
|
| 16 |
+
- **BS_files_with_less_than_25_percent_zeros.csv**: Filtered dataset with entries containing less than 25% missing or zero values.
|
| 17 |
+
- **TIFF files** in each zip file (`pre.zip`, `during.zip`, `post.zip`) capturing burn scar and HLS data at different burn stages.
|
| 18 |

## Dataset Structure
|
| 21 |
+
|
| 22 |
+
### Zipped Files
|
| 23 |
+
Each zip file (`pre.zip`, `during.zip`, `post.zip`) contains paired TIFF files for each burn scar case:
|
| 24 |
+
- **BS_casename.tiff**: 224x224 pixel file with one band, representing burn scar intensity classes (values: 0-4).
|
| 25 |
+
- **HLS_casename.tiff**: 224x224 pixel file with six bands, representing TOA reflectance values across different wavelengths.
|
| 26 |
+
|
| 27 |
+
### TIFF Metadata
|
| 28 |
+
Each TIFF file has the following specifications:
|
| 29 |
+
|
| 30 |
+
#### **Burn Scar Intensity Files (`BS_casename.tiff`)**
|
| 31 |
+
- **Bands**: 1 band
|
| 32 |
+
- **Data Range**: Burn scar intensity classes (0-4), where:
|
| 33 |
+
- **0**: No burn
|
| 34 |
+
- **1**: Unburned to Very Low
|
| 35 |
+
- **2**: Low Severity
|
| 36 |
+
- **3**: Moderate Severity
|
| 37 |
+
- **4**: High Severity
|
| 38 |
+
|
| 39 |
+
#### **HLS TOA Reflectance Files (`HLS_casename.tiff`)**
|
| 40 |
+
- **Bands**: 6 bands, each capturing TOA reflectance at different wavelength.
|
| 41 |
+
- **Wavelengths and Band Mapping**:
|
| 42 |
+
- **Band 1 (Blue, B02)**: 458-523 nm
|
| 43 |
+
- **Band 2 (Green, B03)**: 543-578 nm
|
| 44 |
+
- **Band 3 (Red, B04)**: 650-680 nm
|
| 45 |
+
- **Band 4 (NIR, B8A)**: 845-885 nm
|
| 46 |
+
- **Band 5 (SWIR 1, B11)**: 1560-1660 nm
|
| 47 |
+
- **Band 6 (SWIR 2, B12)**: 2100-2280 nm
|
| 48 |
+
|
| 49 |
+
### CSV Files
|
| 50 |
+
- **BS_files_raw.csv**: Contains raw, unfiltered burn scar intensity data.
|
| 51 |
+
- **BS_files_with_less_than_25_percent_zeros.csv**: Contains burn scar data filtered to include only entries with less than 25% missing or zero values, allowing for enhanced data quality in analysis.
