SHAPES BUFFER
|
|
=============
|
|
|
|
Description
|
|
-----------
|
|
This algorithm creates buffer(s) around features based on fixed distance or distance field.
|
|
|
|
Parameters
|
|
----------
|
|
|
|
- ``Shapes[Vector]``: layer in input (polygons, lines or points)
|
|
- ``Buffer Distance[Selection]``: how the buffer(s) distance has to be calculated (``fixed value`` or ``attribute field``)
|
|
- ``Buffer Distance (Fixed)[Number]``: if fixed is activated, this is the buffer radius (in meters)
|
|
- ``Buffer Distance (Attribute)[TableField]``: field distance of the attribute table (skip this if you have already chosen ``fixed value``)
|
|
- ``Scaling Factor for Attribute Value[Number]``: if you have chosen ``field distance``, set the scaling factor for the values.
|
|
- ``Number of Buffer Zones[Number]``: set the number of buffer features
|
|
- ``Circle Point Distance [Degree][Number]``: this option controls the smoothness of the buffer borders: great numbers means rough borders.
|
|
- ``Dissolve Buffers [Boolean]``: YES if you want to dissolve all buffers into one single feature, NO if you want to keep buffers separated
|
|
|
|
Outputs
|
|
-------
|
|
|
|
- ``Buffer[Vector]``: the resulting buffer
