Set of spatial coordinates that determine a point, defined in coordinate system specified in 'Location.CoordinateSystem', or "WGS 84" if not specified otherwise. Use a single position point instance to desribe a point-oriented location. Use a sequence of position points to describe a line-oriented object (physical location of non-point oriented objects like cables or lines), or area of an object (like a substation or a geographical zone - in this case, have first and last position point with the same values).
