Understanding the Utility Network: A Guide for Water Utilities APRIL 2019 6 With The ArcGIS Utility Network Management extension, utilities can model the connectivity between features that are geometrically coincident as well as features that are offset from each other. These connections between offset features enable optimized feature placement for display purposes. This also enables connectivity of features that are adjacent yet don't have a length of pipe connecting them such as adjoining features in a valve assembly. While the utility network data model allows modeling features in greater detail, this can create cluttered and difficult to read map representations. The containment model solves this by enabling representations of dense features within a container. These features are only displayed when viewing this container. Examples include pump stations, meter pits, and valve assemblies. Figure 2: Features in containment can be hidden from view to declutter the map view. A user-defined network rule base specifies exactly which type of features can be connected and associated with another. For example, certain types of fittings are only allowed in certain device assemblies. The network rule base for the utility network is referenced during editing operations to prevent the creation of incorrect connectivity and associations between features. Existing features that violate network rules are flagged on the map for correction. These are represented as error features. The creation of new features that do not adhere to network rules is not allowed. The direction of the flow of resources through the network can be modeled using terminal connections on devices. This allows for more accurate modeling of network behavior and more powerful network analysis. Attribute Rules The utility network uses attribute rules to streamline the editing experience and improve data integrity. Attribute rules are user defined and can be used to autopopulate attribute values, prevent invalid edits, and perform quality assurance checks. Attribute rules are used in tandem with existing geodatabase rules such as domains and subtypes for cohesive editing results. Attribute rules are defined with ArcGIS Arcade scripting expressions. Arcade is a scripting language that can be used across the ArcGIS platform. To learn more about ArcGIS Arcade, see the ArcGIS Arcade web page.
