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 classeswhich 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`.

Class Summary
Coordinate | A lightweight class used to store coordinates on the 2-dimensional Cartesian plane.
Coordinate.DimensionalComparator | Compares two `Coordinate`s, allowing for either a 2-dimensional or 3-dimensional 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 | Constants representing the dimensions of a point, a curve and a surface.
Envelope | Defines a rectangular region of the 2D coordinate plane.
Geometry | The base class for all geometric objects.
GeometryCollection | Basic implementation of `GeometryCollection`.
GeometryCollectionIterator | Iterates over all `Geometry`s in a `GeometryCollection`.
GeometryFactory | Supplies a set of utility methods for building Geometry objects from lists of Coordinates.
IntersectionMatrix | A Dimensionally Extended Nine-Intersection Model (DE-9IM) matrix.
LinearRing | Models an OGC SFS `LinearRing`.
LineSegment | Represents a line segment defined by two `Coordinate`s.
LineString | Basic implementation of `LineString`.
Location | Constants representing the location of a point relative to a geometry.
MultiLineString | Basic implementation of `MultiLineString`.
MultiPoint | Models a collection of `Point`s.
MultiPolygon | Basic implementation of `MultiPolygon`.
Point | Basic implementation of `Point`.
Polygon | Represents a linear polygon, which may include holes.
PrecisionModel | Specifies the precision model of the `Coordinate`s in a `Geometry`.
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

## Package com.vividsolutions.jts.geom Description

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.
