Get shapes extents

Description

Creates polygons according to the extent of the input layer features.

Parameters

Shapes [vector: any]
Input layer.
Parts [boolean]

Determines whether create polygon for each feature (True) or just create single polygon for whole layer (False).

Merge shapes layers

Description

Merges two or more input layer into a unique resulting layer. You can merge together only layer of the same type (polygons with polygons, lines with lines, points with points).

The attribute table of the resulting layer will include only the attributes of the first input layer. Two additional columns will be added: one corresponding to the ID of every merged layer and the other one corresponding to the original name of the merged layer.

Parameters

Main Layer [vector: any]
Initial layer.
Additional Layers [multipleinput: any vectors]

Optional.

Layer(s) to merge with.

Outputs

Merged Layer [vector]
The resulting layer.

Console usage

processing.runalg('saga:mergeshapeslayers', main, layers, out)
