Tools

Buffer

This algorithm computes a buffer area for all the features in an input layer, using a fixed or dynamic distance. The segments parameter controls the number of line segments to use to approximate a quarter circle when creating rounded offsets. The end cap style parameter controls how line endings are handled in the buffer. The join style parameter specifies whether round, miter or beveled joins should be used when off setting corners in a line. The miter limit parameter is only applicable for miter join styles, and controls the maximum distance from the offset curve to use when creating a mitered join.

Step 1: Type input:

Update

Computes a geometric intersection of the input features and update features. The attributes and geometry of the input features are updated by the update features in the output feature class

Step 1: Type input

Type Name
Select destination folder to contain result
Select vector from Vectors or layer from Layers Control. The input features must be polygon.
Select vector from Vectors or layer from Layers Control. The update features must be polygon.
Select Keep borders: If option Borders is checked (default), the outside border of the update features will be kept in the output. Else if option No borders is checked, the outside border of the update features are dropped after they are inserted into the input features. Item values of the update features take precedence over input features attributes.

Step 2: Click “Submit” button

After task is successful, check vector in Vectors menu.
