## Dataset Summary |
|
|
|
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. |
|
Each file provides spatial information on burn scar intensity and top-of-atmosphere (TOA) reflectance values. |
|
|
|
The dataset includes: |
|
- **BS_files_raw.csv**: The complete set of burn scar intensity data without filtering. |
|
- **BS_files_with_less_than_25_percent_zeros.csv**: Filtered dataset with entries containing less than 25% missing or zero values. |
|
- **TIFF files** in each zip file (`pre.zip`, `during.zip`, `post.zip`) capturing burn scar and HLS data at different burn stages. |
|
|

## Dataset Structure |
|
|
|
### Zipped Files |
|
Each zip file (`pre.zip`, `during.zip`, `post.zip`) contains paired TIFF files for each burn scar case: |
|
- **BS_casename.tiff**: 224x224 pixel file with one band, representing burn scar intensity classes (values: 0-4). |
|
- **HLS_casename.tiff**: 224x224 pixel file with six bands, representing TOA reflectance values across different wavelengths. |
|
|
|
### TIFF Metadata |
|
Each TIFF file has the following specifications: |
|
|
|
#### **Burn Scar Intensity Files (`BS_casename.tiff`)** |
|
- **Bands**: 1 band |
|
- **Data Range**: Burn scar intensity classes (0-4), where: |
|
- **0**: No burn |
|
- **1**: Unburned to Very Low |
|
- **2**: Low Severity |
|
- **3**: Moderate Severity |
|
- **4**: High Severity |
|
|
|
#### **HLS TOA Reflectance Files (`HLS_casename.tiff`)** |
|
- **Bands**: 6 bands, each capturing TOA reflectance at different wavelength. |
|
- **Wavelengths and Band Mapping**: |
|
- **Band 1 (Blue, B02)**: 458-523 nm |
|
- **Band 2 (Green, B03)**: 543-578 nm |
|
- **Band 3 (Red, B04)**: 650-680 nm |
|
- **Band 4 (NIR, B8A)**: 845-885 nm |
|
- **Band 5 (SWIR 1, B11)**: 1560-1660 nm |
|
- **Band 6 (SWIR 2, B12)**: 2100-2280 nm |
|
|
|
### CSV Files |
|
- **BS_files_raw.csv**: Contains raw, unfiltered burn scar intensity data. |
|
- **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. |
