## 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.
