+## ST_Intersection_Aggr
+
+Introduction: Return the polygon intersection of all polygons in A
+
+Format: `ST_Intersection_Aggr (A:geometryColumn)`
+
+Since: `v1.5.0`
+
+SQL example:
+```sql
+SELECT ST_Intersection_Aggr(polygondf.polygonshape)
+FROM polygondf
+```
+
 ## ST_Union_Aggr
 
 Introduction: Return the polygon union of all polygons in A. All inputs must be polygons.
