Geometric networks

In the real world, examples of networks abound: streams joining together to form larger streams, pipes carrying water to homes and businesses throughout a city, and power lines carrying electricity.

In a geodatabase, you can model each of these real-world networks with a geometric network. Created from point and line feature classes grouped together in a feature dataset, geometric networks enable you to define and analyze the flow of resources to answer questions such as:

· Which streams will be affected by a proposed dam?

· Which areas will be affected by a water main repair?

· What is the quickest route between two points in the network?

A water transmission network is modeled in the geodatabase using a geometric network.

To create and edit a geometric network, you need an ArcEditor or ArcInfo license.
