## Zusammenfassung

Geometry objects define a spatial location and an associated geometric shape.

## Diskussion

Bei vielen Workflows der Geoverarbeitung möchten Sie eventuell bestimmte Vorgänge mit Koordinaten- und Geometriedaten ausführen, jedoch nicht unbedingt eine neue (temporäre) Feature-Class erstellen, diese mit Cursorn füllen, die Feature-Class verwenden und dann die vorläufige Feature-Class wieder löschen. Sie können anstelle von Eingabe und Ausgabe auch Geometrieobjekte verwenden und so die Geoverarbeitung vereinfachen. Geometrieobjekte können von Grund auf neu mit Geometry-, Multipoint-, PointGeometry-, Polygon- oder Polyline-Classes erstellt werden.

During the creation of a geometry object, a simplification process is performed to make the geometry topologically consistent according to its geometry type. For instance, it rectifies polygons that may be self-intersecting or contain incorrect ring orientations. Coordinates may move within the resolution of the geometry's spatial reference.

## Methodenübersicht

Methode | Erläuterung |

angleAndDistanceTo (other, {method}) | Returns a tuple of angle and distance to a point or polygon. |

boundary () | Constructs the boundary of the geometry. |

buffer (distance) | Constructs a polygon at a specified distance from the geometry. |

clip (envelope) | Constructs the intersection of the geometry and the specified extent. |

contains (second_geometry, {relation}) | Indicates if the base geometry contains the comparison geometry. contains is the opposite of within. Only True relationships are shown in this illustration. |

convexHull () | Constructs the geometry that is the minimal bounding polygon such that all outer angles are convex. |

crosses (second_geometry) | Gibt an, ob die beiden Geometrien sich in einer Geometrie mit einem geringeren Shape-Typ überschneiden. Zwei Polylinien kreuzen sich, wenn sie nur Punkte gemeinsam haben, von denen mindestens einer kein Endpunkt ist. Eine Polylinie und ein Polygon kreuzen sich, wenn sie im Inneren des Polygons eine Polylinie oder einen Punkt (für eine vertikale Linie) gemeinsam haben, die bzw. der nicht der gesamten Polylinie entspricht. Only True relationships are shown in this illustration. |

cut (cutter) | Splits this geometry into a part left of the cutting polyline, and a part right of it. When a polyline or polygon is cut, it is split where it intersects the cutter polyline. Each piece is classified as left of or right of the cutter. This classification is based on the orientation of the cutter line. Parts of the target polyline that do not intersect the cutting polyline are returned as part of the right of result for that input polyline. If a geometry is not cut, the left geometry will be empty (None). |

densify (method, distance, {deviation}) | Creates a geometry with added vertices. |

difference (other) | Constructs the geometry that is composed only of the region unique to the base geometry but not part of the other geometry. The following illustration shows the results when the red polygon is the source geometry. |

disjoint (second_geometry) | Gibt an, ob die Basis- und die Vergleichsgeometrie keine gemeinsamen Punkte aufweisen. Zwei Geometrien überschneiden sich, wenn disjoint den Wert False zurückgibt. Only True relationships are shown in this illustration. |

distanceTo (other) | Returns the minimum distance between two geometries. The distance is in the units of the geometry's spatial reference. If the geometries intersect, the minimum distance is 0. Both geometries must have the same projection. |

equals (second_geometry) | Indicates if the base and comparison geometries are of the same shape type and define the same set of points in the plane. This is a 2D comparison only; M and Z values are ignored. Only True relationships are shown in this illustration. |

generalize (max_offset) | Creates a new simplified geometry using a specified maximum offset tolerance. |

getArea ({method}, {units}) | Returns the area of the feature using a measurement method. |

getLength ({method}, {units}) | Returns the length of the feature using a measurement method. |

getPart ({index}) | Returns an Array object of Point objects for a particular part of the geometry if an index is specified. If an index is not specified, an Array object containing an Array of Point objects for each geometry part is returned. The getPart method is equivalent to indexing an object; that is, obj.getPart(0) is equivalent to obj[0]. |

intersect (other, dimension) | Constructs a geometry that is the geometric intersection of the two input geometries. Different dimension values can be used to create different shape types. The intersection of two geometries of the same shape type is a geometry containing only the regions of overlap between the original geometries. For faster results, test if the two geometries are disjoint before calling intersect. |

measureOnLine (in_point, {use_percentage}) | Returns a measure from the start point of this line to the in_point. |

overlaps (second_geometry) | Gibt an, üb die Überschneidung der beiden Geometrien denselben Shape-Typ wie eine der Eingabegeometrien aufweist, aber keiner der Eingabegeometrien entspricht. Only True relationships are shown in this illustration. |

positionAlongLine (value, {use_percentage}, {geodesic}) | Returns a point on a line at a specified distance from the beginning of the line. |

projectAs (spatial_reference, {transformation_name}) | Projects a geometry and optionally applies a geotransformation. To project, the geometry must have a spatial reference, and not have an unknown coordinate system. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is unknown, the coordinates will not be changed. The z- and m-values are not changed by the projectAs method. |

queryPointAndDistance (in_point, {as_percentage}) | Finds the point on the polyline nearest to the in_point and the distance between those points. It also returns information about the side of the line the point is on as well as the distance along the line where the nearest point occurs. |

segmentAlongLine (start_measure, end_measure, {use_percentage}) | Returns a Polyline between start and end measures. Similar to Polyline.positionAlongLine but will return a polyline segment between two points on the polyline instead of a single point. |

snapToLine (in_point) | Returns a new point based on in_point snapped to this geometry. |

symmetricDifference (other) | Constructs the geometry that is the union of two geometries minus the instersection of those geometries. The two input geometries must be the same shape type. |

touches (second_geometry) | Indicates if the boundaries of the geometries intersect. Two geometries touch when the intersection of the geometries is not empty, but the intersection of their interiors is empty. For example, a point touches a polyline only if the point is coincident with one of the polyline end points. Only True relationships are shown in this illustration. |

union (other) | Constructs the geometry that is the set-theoretic union of the input geometries. The two geometries being unioned must be the same shape type. |

within (second_geometry, {relation}) | Indicates if the base geometry is within the comparison geometry. within is the opposite operator of contains. Only True relationships are shown in this illustration. The base geometry is within the comparison geometry if the base geometry is the intersection of the geometries and the intersection of their interiors is not empty. within is a Clementini operator, except in the case of an empty base geometry. |

method | The method used to measure distance. - GEODESIC—The shortest line between any two points on the earth's surface on a spheroid (ellipsoid). One use for a geodesic line is to determine the shortest distance between two cities for an airplane's flight path. This is also known as a great circle line if based on a sphere rather than an ellipsoid.
- GREAT_ELLIPTIC—The line on a spheroid (ellipsoid) defined by the intersection at the surface by a plane that passes through the center of the spheroid and the start and endpoints of a segment. This is also known as a great circle when a sphere is used.
- LOXODROME—The line follows a single compass bearing, or azimuth. Great circle routes are often broken into a series of loxodromes, which simplifies navigation. This is also known as a rhumb line.
- PLANAR—Planar measurements use 2D Cartesian mathematics to calculate lengths and areas. This option is only available when measuring in a projected coordinate system and the 2D plane of that coordinate system will be used as the basis for the measurements. Planar measurements reflect the projection of geographic data onto a 2D surface, and do not account for the curvature of the earth.
