Buffer Tool

Last modified: December 27, 2019

The Buffer tool takes any polygon or polyline spatial object and expands or contracts its extents by a user specified value.

Image displaying how Buffer tool works

This image shows a positive buffer of 1 mile and a negative buffer of -1 mile.

Configure the tool

Specify the Spatial Field that contains the spatial object to be buffered.

Include in Output: User can choose whether or not to include the original spatial object in the output stream. The default is unchecked so the object is not included.

Generalize to 1% of Buffer size: Selected by default. This optimizes speed by cutting down the number of nodes in the buffered object.

Set the BufferSize parameters.

  • Specific Value: User can input a numerical value and all records will be buffered to this size
  • From Field: User can select a numerical field in the connection stream and each record is buffered by the value of that field.
  • Units: User can choose to buffer the object in units of Miles or Kilometers
