Vektorlayerüberlagerung

Zuschneiden

Beschreibung

This algorithm extracts features from the Input Layer that fall within, or partially within, the boundaries of features in the Clip Layer. Input Layer features that fall partially within clip layer feature(s) are split along the boundary of the clip layer feature(s). If any features are selected in the Input and Clip Layers, then only those features are used in the clip operation. If no features are selected then the clip operation is performed using all features. The clip function is also known as the cookie-cutter.

Parameter

Eingabelayer [vector: any]

Der Layer, der die Features enthält, die zugeschnitten werden sollen.

Zuschneidungslayer [vector: any]
The layer containing the features that are used to clip the features in the input layer.
Open output file after running algorithm
Choose whether to load the clipped layer to the map canvas once the clip operation has been completed.

Ausgaben

Clipped [vector]
Where to save the clipped layer. Can be saved to file, a temporary file or a memory layer.

Differenz

Beschreibung

This algorithm extracts features from the Input layer that don’t fall within the boundaries of the Difference layer. Input Layer Features that are partially within Difference layer feature(s) are split along the boundary of the clip layer feature(s). If any features are selected in the Input and Difference Layers, then only those features are used in the operation. If no features are selected, then the operation is performed using all features.

Parameter

Eingabelayer [vector: any]
The layer containing the features that will be reduced.
Unterscheidungslayer [vector: any]
The layer containing the features used to reduce the Input Layer.

Ausgaben

Difference [vector]
Where to save the difference layer. Can be saved to file, a temporary file or a memory layer.

Verwendung der Konsole

Verschneidung

Beschreibung

This algorithm combines features from the Input layer and the Intersect Layer, resulting in features that cover both layers’ features. Input Feature(s) that only partially lie within the other layer’s feature(s) are split along the boundary of the other layer’s feature(s). If any features are selected in the Input and Intersect Layers, then only those features are used in the operation. If no features are selected then the operation is performed using all features.

Parameter

Eingabelayer [vector: any]
One layer containing feature(s) to be combined.
Verschneidungslayer [vector: any]
Second layer containing the feature(s) to be combined.

Ausgaben

Verschneidung [vector]
Where to save the intersection layer. Can be saved to file, a temporary file or a memory layer.

Symetrische Differenz

Beschreibung

This algorithm creates a layer that includes all feature(s) that are in only one of the two input layers. Feature(s) that only partially lie within the other layer’s feature(s) are split along the boundary of the other layer’s feature(s). If any features are selected in the Input and Difference Layers, then only those features are used in the operation. If no features are selected then the operation is performed using all features.

Parameter

Eingabelayer [vector: any]
One layer containing feature(s) to be compared.
Unterscheidungslayer [vector: any]
Second layer containing feature(s) to be compared.

Ausgaben

Symetrische Differenz [vector]
Where to save the symmetrical difference layer. Can be saved to file, a temporary file or a memory layer.

Verwendung der Konsole

Vereinigungen

Beschreibung

This algorithm combines the feature(s) of both layers. Features that lie partially within the other layer’s features will be split. Areas that lie within both layers will be added as new features. If any features are selected in either of the layers, then only those features are used in the operation. If no features are selected then the operation is performed using all features.

Parameter

Eingabelayer [vector: any]
One layer containing feature(s) to be unioned.
Eingabelayer 2 [vector: any]
Second layer containing feature(s) to be unioned.

Ausgaben

Vereinigung [vector]
Where to save the union layer. Can be saved to file, a temporary file or a memory layer.

Verwendung der Konsole

processing.runalg('qgis:union', input, input2, output)
