Summarize Within

Calculate summary statistics for features within polygon zones.

Overview

Summarize within calculates statistics (count, sum, average, etc.) for features that fall within polygon zones.

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
