Detailed 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 int ended 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 J TS attempts to choose a reasonable and consistent alternative. Differences from and elaborations of the SFS are documented in this specification.

Enumeration Type Documentation

◆ GeometryTypeId

enum geos::geom::GeometryTypeId : int

Geometry types.

Enumerator
GEOS_POINT	a point
GEOS_LINESTRING	a linestring
GEOS_LINEARRING	a linear ring (linestring with 1st point == last point)
GEOS_POLYGON	a polygon
GEOS_MULTIPOINT	a collection of points
GEOS_MULTILINESTRING	a collection of linestrings
GEOS_MULTIPOLYGON	a collection of polygons
GEOS_GEOMETRYCOLLECTION	a collection of heterogeneus geometries

◆ Location

enum geos::geom::Location : char

strong

Constants representing the location of a point relative to a geometry.

They can also be thought of as the row or column index of a DE-9IM matrix. For a description of the DE-9IM, see the OpenGIS Simple Features Specification for SQL.

Enumerator
NONE	Used for uninitialized location values.
INTERIOR	DE-9IM row index of the interior of the first geometry and column index of the interior of the second geometry. Location value for the interior of a geometry.
BOUNDARY	DE-9IM row index of the boundary of the first geometry and column index of the boundary of the second geometry. Location value for the boundary of a geometry.
EXTERIOR	DE-9IM row index of the exterior of the first geometry and column index of the exterior of the second geometry. Location value for the exterior of a geometry.
