Image displaying how Buffer tool works

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

[en] Configure the Tool

  1. [en] Specify the SpatialField that contains the spatial object to be buffered.

  2. [en] IncludeinOutput: The 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. [en] Generalize to 1% of Buffer size: Selected by default. This optimizes speed by cutting down the number of nodes in the buffered object.

  4. [en] Set the BufferSize parameters.

    • [en] SpecificValue: Input a numerical value and all records are buffered to this size

    • [en] FromField: Select a numerical field in the connection stream and each record is buffered by the value of that field.

    • [en] Units: Choose to buffer the object in units of Miles or Kilometers.
