Statistics
- Count: Number of features in zone
- Sum: Sum of numeric values

- Min/Max: Minimum/maximum values
Example
{
"input_dataset_id": 123,
"zone_dataset_id": 124,
"statistics": ["count", "sum", "average"]
}
Use Cases
- Zonal statistics
- Aggregated analysis
- Summary reporting
- Data aggregation
