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  A factory to create concrete instances of CoordinateSequence s. 
CoordinateSequenceFilter  Interface for classes which provide operations that
can be applied to the coordinates in a CoordinateSequence . 
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 . 
Lineal  Identifies Geometry subclasses which
are 1dimensional and have components which are LineString s. 
Polygonal  Identifies Geometry subclasses which
are 2dimensional
and have components which have Lineal boundaries. 
Puntal  Identifies Geometry subclasses which
are 0dimensional and with components which are Point s. 
Class Summary  

Coordinate  A lightweight class used to store coordinates on the 2dimensional Cartesian plane. 
Coordinate.DimensionalComparator  Compares two Coordinate s, allowing for either a 2dimensional
or 3dimensional comparison, and handling NaN values correctly. 
CoordinateArrays  Useful utility functions for handling Coordinate arrays 
CoordinateArrays.BidirectionalComparator  A Comparator for Coordinate arrays
modulo their directionality. 
CoordinateArrays.ForwardComparator  A Comparator for Coordinate arrays
in the forward direction of their coordinates,
using lexicographic ordering. 
CoordinateList  A list of Coordinate s, which may
be set to prevent repeated coordinates from occuring in the list. 
CoordinateSequenceComparator  Compares two CoordinateSequence s. 
CoordinateSequences  Utility functions for manipulating CoordinateSequence s 
DefaultCoordinateSequenceFactory  Deprecated. no longer used 
Dimension  Provides constants representing the dimensions of a point, a curve and a surface. 
Envelope  Defines a rectangular region of the 2D coordinate plane. 
Geometry  A representation of a planar, linear vector geometry. 
GeometryCollection  Models a collection of Geometry s of
arbitrary type and dimension. 
GeometryCollectionIterator  Iterates over all Geometry s in a Geometry ,
(which may be either a collection or an atomic geometry). 
GeometryFactory  Supplies a set of utility methods for building Geometry objects from lists of Coordinates. 
IntersectionMatrix  Models a Dimensionally Extended NineIntersection Model (DE9IM) matrix. 
LinearRing  Models an OGC SFS LinearRing . 
LineSegment  Represents a line segment defined by two Coordinate s. 
LineString  Models an OGCstyle LineString . 
Location  Constants representing the different topological locations
which can occur in a Geometry . 
MultiLineString  Models a collection of (@link LineString}s. 
MultiPoint  Models a collection of Point s. 
MultiPolygon  Models a collection of Polygon s. 
OctagonalEnvelope  A Bounding Container which is in the shape of an octagon. 
Point  Implementation of Point . 
Polygon  Represents a linear polygon, which may include holes. 
PrecisionModel  Specifies the precision model of the Coordinate s in a Geometry . 
PrecisionModel.Type  The types of Precision Model which JTS supports. 
Triangle  Represents a planar triangle, and provides methods for calculating various properties of triangles. 
Exception Summary  

TopologyException  Indicates an invalid or inconsistent topological situation encountered during processing

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.
