A buffer is a zone that is drawn around a topology. For example, you might specify a buffer on either side of a river to show the extent of a flood plain.
Use Buffer Analysis to show an area around an existing topology. In this case, the buffer analysis of the power line network topology creates a new polygon topology.
For buffering, you create a new polygon topology from an existing node, network, or polygon topology and specify a buffer offset.
The buffer offset can be:
- A positive or negative numeric value
- An expression
- A value specified by object data
- A value linked to an external database record
You can use negative offset values for polygon topologies only.
