Grouped geometry envelope

Supported in: Batch

Returns the envelope of all valid geometries in the given column. Invalid geometries are treated as null and ignored.

Expression categories: Geospatial

Declared arguments

• Expression - Column of geometries to compute the envelope of.
  Expression<Geometry>

Output type: Geometry
