Interface Polygon
- All Superinterfaces:
- GenericSurface, SurfacePatch
- All Known Subinterfaces:
- Triangle
@UML(identifier="GM_Polygon",
specification=ISO_19107)
public interface Polygon
- extends SurfacePatch
A surface patch that is defined by a set of boundary curves and an underlying surface to
which these curves adhere. The default is that the curves are coplanar and the polygon
uses planar interpolation in its interior.
- Since:
- GeoAPI 2.0
- Version:
- ISO 19107

SurfaceBoundary getBoundary()
- The surface boundary that is the boundary of this polygon.
The boundary of a surface patch need not be in the same complex
as the containing surface. The curves that are contained in the
interior of the surface (act as common boundary to 2 surface patches)
are not part of any complex in which the surface
is contained. They are purely constructive and would not play in any topological relation
between surface and curve that defines the connectivity
of the complex.

- Returns:
- The boundary of this
SurfacePatch
getSpanningSurface
@UML(identifier="spanningSurface",
obligation=OPTIONAL,
specification=ISO_19107)
List<Surface> getSpanningSurface()
- Provides a mechanism for spanning the interior of the polygon.
The spanning surface should have no boundary components that intersect the boundary of the
polygon, and there should be no ambiguity as to which portion of the surface is described by
the bounding curves for the polygon. The most common spanning surface is an elevation model,
which is not directly described in this standard, although tins and
gridded surfaces are often used in this role.
