## 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. |
