      """
      Test for 'almost' geometric equality. Empty or missing geometries
      considered equal.
  
      This method allows small difference in the coordinates, but this
      requires coordinates be in the same order for all components of a geometry.
  
      Parameters
      ----------
      this, that : arrays of Geo objects
  
      Returns
      -------
      Series
          boolean Series, True if geometries in left almost equal geometries in right
