Class SFSProfiler

java.lang.Object
  org.deegree.geometry.SFSProfiler

public class SFSProfiler
extends Object

Converts a generic deegree Geometry instance (which may be anything from the ISO 19107 model) into a Geometry that matches the capabilities of the Simple Feature Specification (SFS).

General conversion scheme

• Point -> Point
• LineString -> LineString
• Curve -> LineString
• Polygon -> Polygon (using only a patch with linear interpolated boundaries)
• Surface -> Polygon/MultiPolygon (one member for every surface patch, each using linear interpolated boundaries)
• MultiPoint -> MultiPoint
• MultiLineString -> MultiLineString
• MultiCurve -> MultiLineString
• MultiPolygon -> MultiPolygon (members using only a patch with linear interpolated boundaries)
• MultiSurface -> MultiPolygon (members using only a single patches with linear interpolated boundaries)
