Detailed Description

Computes the centroid of a Geometry of any dimension.

If the geometry is nomimally of higher dimension, but contains only components having a lower effective dimension (i.e. zero length or area), the centroid will be computed appropriately.

Algorithm

If the input geometries are empty, a null Coordinate is returned.

Gets the computed centroid.

Parameters
centwill be set to the centroid point, if any
Returns
true if a centroid could be computed, false otherwise (empty geom)
