# 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
|
|
|
|
```json
|
|
{
|
|
"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
