Function polygonsUnion

polygonsUnion<
    M = Record<string, unknown>,
    D extends Properties = Properties,
    P extends Properties = Properties,
>(
    polygons:
        | VectorMultiPolygon<D>
        | VectorMultiPolygonGeometry<D>
        | VectorFeatures<M, D, P, VectorMultiPolygonGeometry<D>>,
): VectorMultiPolygonGeometry<D> | undefined
Given a collection of polygons, if any of the polygons interact, merge them as a union
Type Parameters
- M = Record<string, unknown>
- D extends Properties = Properties
- P extends Properties = Properties
Parameters
- polygons:
      | VectorMultiPolygon<D>
      | VectorMultiPolygonGeometry<D>
      | VectorFeatures<M, D, P, VectorMultiPolygonGeometry<D>>
  the polygons are from either a VectorFeature, VectorPolygonGeometry, or raw VectorPolygon
Returns VectorMultiPolygonGeometry<D> | undefined
- a union of polygons should a union exist.
