About polygons

Polygons and node polygons provide a method for specifying a geographical area on the GeoPlan window.

You can use polygons:

• for property counting
• to make a network summary more specific
• to define sub-networks or zones characterised by the same area code so that the network is divided into smaller more manageable areas in IWLive Pro.

In addition, polygons themselves can be grouped into polygon categories.

Polygons and node polygons are used to calculate demand when allocating land use demand to nodes.

The other topics in this section describe the creation and use of polygons and polygon categories in more detail.
