## Quality Indicators

✅ **Excellent Coverage** (≥95%)

✅ **No Invalid Coordinates**

❌ **Low GeoNames Coverage** (0.0%)

## Recommendations

3. **Enhance GeoNames IDs**:
   - GeoNames IDs enable better geographic linking
   - Consider querying GeoNames API directly
   - Use reverse geocoding to find GeoNames IDs
