Sinopse
float ST_ZSize(box3d aGeomorBox2DorBox3D);
Descrição
Returns the Z size of a 2D or 3D bounding box or a geometry, computed as ST_ZMax(aGeomorBox2DorBox3D) - ST_ZMin(aGeomorBox2DorBox3D).

Although this function is only defined for box3d, it also works for box2d and geometry values due to automatic casting. However it will not accept a geometry or box2d text representation, since those do not auto-cast. |
This function supports 3d and will not drop the z-index.
This method supports Circular Strings and Curves.
Availability: 3.7.0
