Constructor Detail

DefaultSurface

public DefaultSurface(String id,
                      CRS crs,
                      PrecisionModel pm,
                      List<? extends SurfacePatch> patches)

Creates a new DefaultSurface instance from the given parameters.

Parameters:

id - identifier, may be null

crs - coordinate reference system, may be null

pm - precision model, may be null

patches - patches that constitute the surface

Method Detail

getCoordinateDimension

public int getCoordinateDimension()

Description copied from interface: Geometry

Returns the coordinate dimension, i.e. the dimension of the space that the geometry is embedded in.

Specified by:

getCoordinateDimension in interface Geometry

Returns:

the coordinate dimension

getGeometryType

public Geometry.GeometryType getGeometryType()

Description copied from interface: GeometricPrimitive

Must always return Geometry.GeometryType#PRIMITIVE_GEOMETRY.

Specified by:

getGeometryType in interface Geometry

Specified by:

getGeometryType in interface GeometricPrimitive

Returns:

must always return Geometry.GeometryType#PRIMITIVE_GEOMETRY

getPrimitiveType

public GeometricPrimitive.PrimitiveType getPrimitiveType()

Description copied from interface: Surface

Must always return GeometricPrimitive.PrimitiveType.Surface.

Specified by:

getPrimitiveType in interface GeometricPrimitive

Specified by:

getPrimitiveType in interface Surface

Returns:

GeometricPrimitive.PrimitiveType.Surface

getSurfaceType

public Surface.SurfaceType getSurfaceType()

Description copied from interface: Surface

Returns the type of surface.

Specified by:

getSurfaceType in interface Surface

Returns:

the type of surface

getArea

public Measure getArea(Unit requestedBaseUnit)

Specified by:

getArea in interface Surface

Returns:

area of the surface

getPatches

public List<? extends SurfacePatch> getPatches()

Description copied from interface: Surface

Returns the patches that constitute this surface.

Specified by:

getPatches in interface Surface

getExteriorRingCoordinates

public Points getExteriorRingCoordinates()

Description copied from interface: Surface

Convenience method for accessing the control points of the exterior ring of a simple polygon surface.

NOTE: This method is only safe to use when the surface consists of a single planar patch that has a linear interpolated exterior ring.

Specified by:

getExteriorRingCoordinates in interface Surface

Specified by:

getInteriorRingsCoordinates in interface Surface

Returns:

the control points

buildJTSGeometry

protected com.vividsolutions.jts.geom.Geometry buildJTSGeometry()

Overrides:

buildJTSGeometry in class AbstractDefaultGeometry
