character string 'austalbers' to
use the Australian Albers Equal Area projection. Ignored if the polygonlayer
is projected in which case the targetlayer will be converted to the
projection used by the polygonlayer. In all cases the resulting object will
be reprojected to the original coordinate system and projection of the
polygon layer. Default is an Albers Equal Area projection but for more
reliable results should use a local projection (e.g., Australian Albers
Equal Area project).</p></td>
