Buffering a Topology
Concept Procedure Quick Reference
 
 
 

A buffer analysis identifies objects within a specified offset of elements in node, network, and polygon topologies. 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.

Note that topologies can contain only drawing objects.

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:

You can use negative offset values for polygon topologies only.

Tip You can improve the performance of buffering operations by increasing the RAM to more than the recommended amount, or by increasing the virtual memory on your system. This is recommended if you are buffering large topologies.
