Utility network

A comprehensive ArcGIS model of a utility system that represents features, their connectivity, and the rules governing how assets interact, enabling tracing, analysis, and network management across an entire system.

Related: Connectivity, Trace, Domain network
Feature dataset

A container in a geodatabase that groups related feature classes sharing a common spatial reference. A utility network and all its participating feature classes must reside within one feature dataset.

Related: Feature class, Geodatabase
Feature class

A collection of features with the same geometry type, attributes, and behavior stored in a geodatabase. Utility network feature classes represent assets such as lines, devices, and junctions.

Related: Asset group, Feature dataset
Asset group

A classification of features within a feature class, such as Electric Distribution Line or Water Main, that provides the first level of asset categorization and drives which asset types and rules apply.

Related: Asset type, Feature class
Asset type

A subtype within an asset group, such as a specific pipe material or conductor size, used to further categorize assets and associate them with network rules and terminal configurations.

Related: Asset group, Subtype
Domain network

A logical partition of a utility network representing one utility service or system, such as electric distribution or water pressure zone, each with its own tier, subnetwork, and tracing behavior.

Related: Tier, Subnetwork, Utility network
Tier

A grouping of subnets within a domain network that defines hierarchical levels, such as transmission above distribution, and controls how subnetworks interact during propagation and tracing.

Related: Subnetwork, Domain network
Subnet

A contiguous portion of a domain network sharing a common source or resource, such as a pressure zone or an electrical circuit, managed and tracked through subnetwork controllers.

Related: Subnetwork controller, Subnetwork
Subnetwork

The set of network features energized or served by a specific subnetwork controller, derived dynamically through tracing and used for isolation, outage analysis, and network management.

Related: Subnet, Subnetwork controller, Trace
Subnetwork controller

A feature, such as a circuit breaker or pressure reducing valve, that acts as the source or boundary for a subnetwork and governs how the subnetwork is built and updated.

Related: Subnetwork, Subnet
Connectivity

The logical relationship between features in a utility network based on geometric coincidence and network rules, determining how assets are linked and how resources flow through the system.

Related: Geometric coincidence, Connectivity rule, Junction
Geometric coincidence

The spatial overlap of endpoints or vertices of line features and points of junction features that establishes connectivity when the network is built or validated.

Related: Connectivity, Snap tolerance
Connectivity rule

A rule that defines which asset groups and asset types may connect to one another, preventing invalid connections such as a water main joining an electric line.

Related: Connectivity, Association rule, Network rule
Association

A relationship between features that is not purely geometric, such as containment, attachment, or connectivity association, used to model dependencies like a transformer bank or a service point.

Related: Association rule, Connectivity
Association rule

A rule that constrains which feature classes, asset groups, and asset types may participate in an association, ensuring valid relationships such as attachments to the correct container type.

Related: Association, Network rule
Network rule

A configurable constraint in a utility network that governs valid connectivity and associations between asset types, enforced when features are edited or the network is validated.

Related: Connectivity rule, Association rule
Terminal

A connection point on a device or junction feature, such as the primary or secondary side of a transformer, that defines where lines may attach and how flow is directed.

Related: Terminal configuration, Device
Terminal configuration

The arrangement of terminals and their connectivity on a device, defining which terminals are internally connected and how resources pass through the device during tracing.

Related: Terminal, Device
Device

A point feature that represents an asset capable of controlling flow or performing a function, such as a switch, valve, or transformer, typically modeled with terminals.

Related: Terminal, Junction
Junction

A point feature representing a connection or transition point in the network, such as a fitting, tap, or service point, that does not necessarily control flow.

Related: Device, Connectivity
Trace

An analysis operation that traverses the network from starting points according to specified conditions, such as upstream, downstream, connected, or isolation traces, to answer operational questions.

Related: Trace configuration, Subnetwork, Barrier
Trace configuration

A named set of parameters, including trace type, traversability, filters, and output options, that defines how a trace executes and what results it returns.

Related: Trace, Filter, Barrier
Barrier

A feature or condition, such as an open switch or closed valve, that stops or limits traversal during a trace, used to model isolation or outage scenarios.

Related: Trace, Trace configuration
Filter

A trace parameter that restricts which features or associations are included in results, for example by asset type, function, or category, narrowing the output of a trace.

Related: Trace configuration, Trace
Dirty area

A geographic region flagged when edits occur, indicating that the network topology or subnetworks may be out of date and require validation to restore consistency.

Related: Validate, Network topology
Validate

The process of rebuilding network topology and updating subnetworks within dirty areas after edits, ensuring connectivity, rules, and traces reflect current data.

Related: Dirty area, Network topology
Network topology

The indexed, logical representation of connectivity and associations in a utility network, stored separately from the feature geometry and used to power tracing and validation.

Related: Validate, Connectivity
Versioning

A geodatabase capability that allows multiple users to edit the same data concurrently through versions, with utility networks requiring branch versioning for editing workflows.

Related: Branch versioning, Reconcile and post
Branch versioning

A versioning model using named versions managed through services, required for utility network editing, supporting long transactions and conflict management in enterprise deployments.

Related: Versioning, Reconcile and post
Reconcile and post

The workflow of merging edits from a child version into a parent version, resolving conflicts, and then posting changes to the default version in a branch versioned geodatabase.

Related: Branch versioning, Versioning
Attribute rule

A geodatabase rule that automatically calculates attribute values or validates edits when features are created or updated, used to enforce data quality in utility networks.

Related: Network rule, Subtype
Subtype

A classification within a feature class that groups features with shared behavior and default values, often corresponding to asset groups in a utility network data model.

Related: Asset group, Asset type
Utility network service

A web service that publishes a utility network and its feature layers, enabling editing, tracing, and analysis through ArcGIS clients and APIs.

Related: Publish, Web map
Publish

The process of sharing a utility network and its related layers as a web service or web map so that users and applications can access, edit, and analyze the data.

Related: Utility network service, Web map
Web map

A shareable ArcGIS document that references layers and services, used to configure and share utility network content, symbology, and pop-ups with other users.

Related: Publish, Utility network service
Portal

An ArcGIS Enterprise component that provides authentication, sharing, and content management for web maps, services, and applications in a utility network deployment.

Related: Federated server, Publish
Federated server

An ArcGIS Server site that is registered with and managed through a portal, hosting utility network services and enabling centralized sharing and security.

Error feature

A feature generated during validation when a network rule is violated, such as an invalid connection, allowing editors to identify and correct data problems.
