Questions tagged [geometric-network]

A geometric network is a set of connected edges and junctions (nodes) along with connectivity rules that are used to represent and model the behavior of a common network infrastructure in the real world. Geodatabase feature classes are used as the data sources to define the geometric network. You define the roles that various features will play in the geometric network and rules for how resources flow through the geometric network.
