The trace network provides a capability to migrate geometric networks into ArcGIS Pro with the Convert Geometric Network To Trace Network tool. This process uses the input geometric network's configuration (junctions, edges, network weights, and weight assignments) to configure a new trace network.
Caution:
The process to convert a geometric network to a trace network drops the geometric network and creates a trace network in place. There is no way to undo this change. Ensure you have a backup of your data before proceeding.
Requirements
- A trace network can be created with z-enabled feature classes to support 3D capabilities. Connectivity is established based on x,y,z coincidence when the network topology is created. Connectivity is not determined using z unless all feature classes that participate in the trace network are z-enabled.
The input geodatabase workspace must be a 10.0 or later release to support this functionality.
- When working with an enterprise geodatabase, the following requirements must be met.
The geodatabase version must be 10.8.1.2.6 or later.
- The Input Geometric Network must be from a database connection established as a database-authenticated user and owner of the geometric network. This user must have database privileges to create content and cannot be an OS-authenticated user, a database administrator, or the geodatabase administrator account.
- ArcGIS Enterprise must be 10.9 or later. The version of ArcGIS Pro determines the compatible ArcGIS Enterprise version. For more information, see ArcGIS platform compatibility.
Supported geodatabases
A trace network can be created in a file or enterprise geodatabase. To create a trace network in an enterprise geodatabase, the database platform must meet the minimum release in the table below. For more information, refer to the database requirements for ArcGIS Pro
.
| Database platform | Minimum release |
|---|---|
| SQL Server | SQL Server 2016 |
| Oracle | Oracle 12.1.0.2 |
| PostgreSQL | PostgreSQL 10.12 |
| SAP HANA | HANA 2.0 SPS04 |
To convert a geometric network into a trace network, complete the following steps:
- On the Analysis tab, in the Geoprocessing group, click Tools
to open the Geoprocessing pane. - In the Geoprocessing pane, search for and choose the Convert Geometric Network To Trace Network tool.
- For the Input Geometric Network parameter, specify the geometric network to be converted in either a file or enterprise geodatabase.
- For Output Trace Network Name, specify a name for the output trace network that will be created.
- Click Run.
The input geometric network is converted and replaced with a new trace network in the feature dataset. The network topology can now be enabled for the new trace network to establish connectivity.
