public class SurfaceImpl
- extends GeometryImpl
- implements org.opengis.geometry.primitive.Surface
Surface with a positive orientation.
Surface
is a subclass of Primitive
and is the basis for 2-dimensional
geometry. Unorientable surfaces such as the Möbius band are not allowed. The orientation of
a surface chooses an "up" direction through the choice of the upward normal, which, if the
surface is not a cycle, is the side of the surface from which the exterior boundary appears
counterclockwise. Reversal of the surface orientation reverses the curve orientation of each
boundary component, and interchanges the conceptual "up" and "down" direction of the surface.
If the surface is the boundary of a solid, the "up" direction is usually outward. For closed
surfaces, which have no boundary, the up direction is that of the surface patches, which must
be consistent with one another. Its included surface patches describe
the interior structure of a Surface
.
NOTE: Other than the restriction on orientability, no other "validity" condition is required for GM_Surface.
