A geometric network is an object commonly used in geographic information systems to model a series of interconnected features.
A geometric network is similar to a graph in mathematics and computer science, and can be described and analyzed using theories and concepts similar to graph theory.
A geometric network is composed of edges that are connected.
In the case of utility networks, a source point may correlate with an electric substation or a water pumping station, and a sink point may correlate with a service connection at a residential household.
Through analyzing this connectivity, paths from one point to another on the network can be traced and calculated.
