# WPS Processes

List of all processes available to GeoServer. Click on 'Build process' to launch the process builder for a process.

JTS:contains | Tests if no points of the second geometry lie in the exterior of the first geometry and at least one point of the interior of second geometry lies in the interior of first geometry. | View details Build process |

JTS:isEmpty | Tests if a geometry contains no vertices. | View details Build process |

JTS:length | Returns the total length of all line segments in a geometry. Measurement is given in the source units, so geographic coordinates are not recommended. | View details Build process |

JTS:disjoint | Tests if two geometries do not have any points in common. | View details Build process |

JTS:intersects | Tests if two geometries intersect. | View details Build process |

JTS:isClosed | Tests if the initial vertex equals the final vertex in a linear geometry. Points and polygons always return True. | View details Build process |

JTS:isValid | Tests if a geometry is topologically valid. | View details Build process |

JTS:union | Returns a geometry representing all points contained in any of the geometries in a geometry collection. | View details Build process |

JTS:dimension | Returns the largest dimension of a geometry or geometry collection: 0 for point, 1 for line, 2 for polygon. | View details Build process |

JTS:buffer | Returns a polygonal geometry representing the input geometry enlarged by a given distance around its exterior. | View details Build process |

JTS:intersection | Returns a geometry representing the points that two geometries have in common. The result may be a heterogeneous geometry collection. If no intersection, returns an empty geometry. | View details Build process |

JTS:getX | Returns the X value (first ordinate) for point geometries. For other geometry types returns the X value of the centroid. | View details Build process |

JTS:getY | Returns the Y value (second ordinate) for point geometries. For other geometry types returns the Y value of the centroid. | View details Build process |

JTS:crosses | Tests if two geometries have some, but not all, interior points in common. | View details Build process |

JTS:overlaps | Tests if two geometries share some but not all interior points. Points or lines will always return False. | View details Build process |

JTS:touches | Tests if two geometries have at least one boundary point in common, but share no interior points. | View details Build process |

JTS:within | Tests if the first geometry is contained in the second geometry. | View details Build process |

JTS:distance | Returns the minimum distance between two geometries. Measurement is given in the input units, so geographic coordinates are not recommended. | View details Build process |

JTS:equalsExact | Tests if two geometries are identical on a vertex-by-vertex basis. | View details Build process |

JTS:envelope | Returns the smallest bounding box polygon that contains a geometry. For a point geometry, returns the same point. | View details Build process |

JTS:isSimple | Tests if a geometry is topologically simple. Points, polygons, closed line strings, and linear rings are always simple. Other geometries are considered simple if no two points are identical. | View details Build process |

JTS:difference | Returns a geometry representing the points that are contained in a geometry but not contained in a second geometry. The result may be a heterogeneous geometry collection. | View details Build process |

JTS:densify | Returns a spatially equivalent geometry with vertices added to ensure line segments are no longer than a given distance. | View details Build process |

JTS:geometryType | Returns the name of a geometry's type. Values are one of POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, GEOMETRYCOLLECTION. | View details Build process |

JTS:boundary | Returns a geometry boundary. For polygons, returns a linear ring or multi-linestring equal to the boundary of the polygon(s). For linestrings, returns a multipoint equal to the endpoints of the linestring. For points, returns an empty geometry collection. | View details Build process |
