11.5.3.1 Geometry Functions That Produce New Geometries
In the section section 11.5.2 Geometry Property Analysis Functions,
we've already discussed some functions that can construct new geometries
from the existing ones:
Envelope(g)StartPoint(ls)EndPoint(ls)PointN(ls,n)ExteriorRing(poly)InteriorRingN(poly,n)GeometryN(gc,n)
