Dissolve Network (Network Analyst)

ArcGIS Pro 3.4 | | Help archive

Summary

Creates a network dataset that minimizes the number of line features required to correctly model the input network dataset. The more efficient output network dataset reduces the time required to solve analyses, draw results, and generate driving directions. This tool outputs a new network dataset and source feature classes; the input network dataset and its source features remain unchanged.

Usage

  • This tool does not create a built network. Use the Build Network tool to build the newly created network dataset prior to performing any analysis on it.

  • The network dataset and feature classes created in the output geodatabase workspace have the same feature dataset name, network dataset name, and feature class names as the input network dataset. The tool fails to execute if any datasets with these names already exist in the output geodatabase workspace.

  • Only fields from the source feature class that are used by the network dataset are transferred to the output line feature class. Examples of fields include:

    • Elevation fields
    • Fields used in network attribute evaluators (length, time, one-way restrictions, hierarchy, and so on)
    • Fields used in generating driving directions (Street names, Shield, and so on)
  • If the network dataset being dissolved does not contain any 10.1 functionality, a 10.0 network dataset is created.

Parameters

LabelExplanationData Type
Input Network Dataset

The network dataset to be dissolved.

The input network dataset must be a file or personal geodatabase network dataset with exactly one edge source. Any number of junction sources and turn sources is allowed. The edge source must have:

  • End point connectivity policy
  • An elevation policy of either None or Elevation Fields

The input network dataset must be built before it can be used in this tool.

Network Dataset Layer
Output Geodatabase Workspace

The geodatabase workspace in which to create the dissolved network dataset. The workspace must be an ArcGIS 10 geodatabase or later, and it must be a different geodatabase than the one where the input network dataset resides.

Derived Output

LabelExplanationData Type
Output Dissolved Network Dataset

A network dataset with fewer line features, which results in faster network analyses.
