## Quality Metric IXN Calculation

This page explains how to use the Quality Metric IXN Calculation job to calculate intersection quality metrics for a dataset.

---

### Function

Calculates the intersection quality metric for a dataset. An optional intersection polygon GeoJSON file can be provided; if not given, Voronoi polygons are generated based on the dataset area. Providing an intersection polygon file is recommended for better performance.
