The Utility Network dataset is a series of feature classes that define the asset groups, asset types, and attributes of the corresponding feature classes in a utility network. For each domain network, excluding the structure network, in the utility network, assembly, device, junction, line, and subnet line feature classes are prefixed with the domain network name. If multiple domain networks are in the utility network, multiple versions of these layers are includes with a prefix for the specific domain.
Domain network feature classes
Five feature classes in the Utility Network dataset correspond to the feature classes of a domain network that participates in a utility network. Each feature class is prefixed with the name of the domain network.
For example, the ElectricDistributionAssembly feature class defines the properties of the assembly feature class in the electric distribution domain in a utility network. Additional feature classes that are part of the Utility Network dataset correspond to the device, junction, line, and subnet line feature classes in a domain network.
The domain network features classes define the asset group, asset types, and attributes of a domain network in a utility network.
Asset groups are defined using subtypes to the feature classes. A subtype with a code of zero (0) is reserved for an Unknown asset group, which is required and automatically added when creating a utility network.
For each asset group, an attribute domain defines the asset type values for the asset type field. If creating your own asset groups in the asset package, follow a standard naming convention, such as AssetType_ElectricDistributionAssembly_<Asset Group Name>.
Attributes for all asset groups and asset types are defined in the feature class.
Structure network feature classes
Three feature classes in the Utility Network dataset (StructureBoundary, StructureJunction, and StructureLine) correspond to the structure network of a utility network.
As with the domain network feature classes, the structure network feature classes define the asset groups, asset types, and attributes.
Asset groups are defined using subtypes to the feature classes. A subtype with a code of zero (0) is reserved for an Unknown asset group, which is required and automatically added when creating a utility network.
For each asset group, an attribute domain defined the asset type values for the asset type field. If creating your own asset groups in the asset package, follow a standard naming convention, such as AssetType_StructureBoundary_<Asset Group Name>.
Attributes for all asset groups and asset types are defined in the feature class.
Service Territory feature class
The Service Territory feature class and utility network supports either a single polygon, multiple polygons, a multipart polygon, or many multipart polygons. Multiple feature classes are not supported.
