Inputs

  • Input Dataset: Point or line dataset to summarize
  • Zone Dataset: Polygon dataset defining zones
  • Statistics: Statistics to calculate

Outputs

New dataset containing:

  • Zone polygons
  • Summary statistics for each zone
  • Zone attributes

Statistics

  • Count: Number of features in zone
  • Sum: Sum of numeric values
  • Average: Average 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

Notes

  • Features must be within zones
  • Multiple statistics can be calculated
  • Results depend on zone boundaries
  • Processing time depends on dataset sizes
