  "latitude": "decimal_degrees", 
  "longitude": "decimal_degrees",
  "event_type": "conflict_type_classification",
  "severity_score": "0.0_to_1.0_scale",
  "confidence": "validation_confidence_level",
  "source_organization": "validating_organization", 
  "date_acquired": "image_acquisition_date",

}
```

## Usage Examples

### Loading Metadata
```python
import pandas as pd
import json

# Load JSONL format
records = []
with open('metadata/unified_mass_atrocity_dataset.jsonl', 'r') as f:
    for line in f:
        records.append(json.loads(line.strip()))

# Or load CSV format
df = pd.read_csv('metadata/unified_mass_atrocity_dataset.csv')
print(f"Total records: {len(df):,}")
```

### Accessing Satellite Imagery
```python
from pathlib import Path
import matplotlib.pyplot as plt
from PIL import Image

# High-resolution imagery path
high_res_path = Path('high_resolution/')
low_res_path = Path('low_resolution/')

# Example: Load specific image
sample_dirs = list(high_res_path.iterdir())[:5]
for img_dir in sample_dirs:
    rgb_image = img_dir / f'{img_dir.name}_rgb.png'
    if rgb_image.exists():
        img = Image.open(rgb_image)
        plt.figure(figsize=(10, 10))
        plt.imshow(img)
        plt.title(f'Sample: {img_dir.name}')
        plt.axis('off')
        plt.show()
```

### Geospatial Analysis
```python
import geopandas as gpd
from shapely.geometry import Point

# Create GeoDataFrame from coordinates
geometry = [Point(record['longitude'], record['latitude']) for record in records]
gdf = gpd.GeoDataFrame(records, geometry=geometry, crs='EPSG:4326')

# Geographic distribution analysis
print("Records by region:")
print(gdf.groupby('source_organization').size())

# Conflict hotspot analysis
conflict_density = gdf.dissolve(by='event_type').geometry.bounds
print("Geographic bounds by conflict type:")
print(conflict_density)
```

## Integration with Text Dataset

This imagery dataset is designed to work seamlessly with the text component of MAID:

```python
# Cross-reference with text dataset
import sys
sys.path.append('../text_dataset')

# Load both datasets
text_records = json.load(open('../text_dataset/comprehensive_mass_atrocity_database_full.json'))
image_records = [json.loads(line) for line in open('metadata/unified_mass_atrocity_dataset.jsonl')]

# Find geographic matches
def find_nearby_incidents(text_lat, text_lon, image_records, threshold_km=10):
    from geopy.distance import geodesic
    matches = []
    for img_record in image_records:
        distance = geodesic((text_lat, text_lon), 
                          (img_record['latitude'], img_record['longitude'])).kilometers
        if distance <= threshold_km:
            matches.append((img_record, distance))
    return sorted(matches, key=lambda x: x[1])

# Example usage
text_incident = text_records['records'][0]
if 'location' in text_incident:
    nearby_imagery = find_nearby_incidents(
        text_incident['location']['latitude'],
        text_incident['location']['longitude'], 
        image_records
    )
    print(f"Found {len(nearby_imagery)} nearby satellite images")
```
