A diagram is a symbolic representation of geographic information drawn with an applied visualization technique.
Schematics, sometimes called schematic diagrams, are diagrams showing simplified representations of networks. These diagrams explain the network structure and the way it operates. They are often used to represent networks in a defined space without scaling constraints. For example, a defined space is a piece of paper where numerous pieces of information are displayed by optimizing the placement of the features. In schematics, there are no scale constraints (cable length, distances, and so forth).
The utility network and trace network provide an integrated mechanism for working with diagrams. It allows you to efficiently create multilevel representations, readily check network connectivity, and obtain logical views of any utility network or trace network.
A utility network or trace network created in a geodatabase contains preconfigured schematic diagramming capabilities that allow the generation of diagrams from the network without specific configurations.
These default diagramming capabilities can be expanded by building your own schematic diagramming models or importing models that were built for another utility network or trace network.
