Description
Interface Summary | |
CoordinateFilter | Geometry classes support the concept of applying a
coordinate filter to every coordinate in the Geometry . |
CoordinateSequence | The internal representation of a list of coordinates inside a Geometry. |
CoordinateSequenceFactory | An object that knows how to build a particular implementation of CoordinateSequence from an array of Coordinates. |
GeometryComponentFilter | Geometry classes support the concept of applying
a GeometryComponentFilter
filter to the Geometry . |
GeometryFilter | GeometryCollection classes support the concept of
applying a GeometryFilter to the Geometry . |
Class Summary | |

CoordinateArrays | Useful utility functions for handling Coordinate arrays |
CoordinateList | A list of Coordinates , which may
be set to prevent repeated coordinates from occuring in the list. |
DefaultCoordinateSequenceFactory | Creates CoordinateSequences internally represented as an array of x's and an array of y's. |
Dimension | Constants representing the dimensions of a point, a curve and a surface. |
Envelope | Defines a rectangular region of the 2D coordinate plane. |
Geometry | Basic implementation of Geometry . |
GeometryCollection | Basic implementation of GeometryCollection . |
GeometryCollectionIterator | Iterates over all Geometry s in a GeometryCollection
. |

Exception Summary | |
TopologyException | Indicates an invalid or inconsistent topological situation encountered during processing |
Contains the Geometry
interface hierarchy and supporting classes.
The Java Topology Suite (JTS) is a Java API that implements a core set of spatial data operations using an explicit precision model and robust geometric algorithms. JTS is intended to be used in the development of applications that support the validation, cleaning, integration and querying of spatial datasets.
JTS attempts to implement the OpenGIS Simple Features Specification (SFS) as accurately as possible. In some cases the SFS is unclear or omits a specification; in this case JTS attempts to choose a reasonable and consistent alternative. Differences from and elaborations of the SFS are documented in this specification.
