Buffer Tool

Last modified: May 11, 2020

Use the Buffer tool to take any polygon or polyline spatial object and expand or contract 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

  1. Specify the Spatial Field that contains the spatial object to be buffered.
  2. 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.
  3. Generalize to 1% of Buffer size: Selected by default. This optimizes speed by cutting down the number of nodes in the buffered object.
  4. Set the BufferSize parameters.
    • Specific Value: Input a numerical value and all records are buffered to this size
    • From Field: Select a numerical field in the connection stream and each record is buffered by the value of that field.
    • Units: Choose to buffer the object in units of Miles or Kilometers.
