Creates a spatial reference based on WKID for the horizontal coordinate system and vertical coordinate system. The method creates a spatial reference that has both horizontal and vertical coordinate systems. When the vertical WKID is null or less than or equal to 0, this is equivalent to calling SpatialReference (wkid: Int), and the spatial reference will not have a vertical coordinate system associated with it. If an error occurs due to an invalid wkid or verticalWkid, this function will return null.

Creates a spatial reference based on well-known text. If the text is invalid, this function will return null.

Creates a spatial reference based on web Mercator. The method creates a web Mercator spatial reference.

Creates a spatial reference based on WGS84. The method creates a WGS84 spatial reference.
