Data Model Changes

After importing the asset package, administrators can make changes to the ArcFM Editor XI data model to meet specific business needs.

Here is some information to consider first.

• Adds, updates, and deletes of fields, tables, or relationships that don’t participate in the Utility Network (UN) have a small impact on the time to implement the project.

• Adds, updates, and deletes of fields, tables, or relationships such as objects used in the UN have a large impact on the time to implement the project.

Service Territory

The asset package includes the Service Territory layer, and it must span the operational and geographical area of your domain. It represents the territory where the network topology is maintained and where Editor XI editing tools are available. This layer becomes crucial later in the Stage the Utility Network step. When creating your Service Territory feature class, it should reside in the same feature dataset as your other asset groups. This ensures it uses the same coordinate system.

• The Service Territory defines the spatial reference for the UN feature classes. If you want to add to, update, or edit the Service Territory, these changes must be done before you create the UN. Once this spatial reference has been defined and the UN has been created, it cannot be changed.

• This feature layer polygon is used to create the UN geographical extent. It must have at least one feature that outlines the service area boundary, plus a reasonable buffer to allow for growth within your utility domain.

• From the Contents pane, right-click on Map and choose Properties. Make sure you choose a projected coordinate system for your map that is appropriate for your service location. You can confirm the selected system in your map properties.

  If working with the downloaded asset package, the Service Territory coordinate system uses NAD 1927 StatePlane Colorado North FIPS 0501. You can confirm this by right-clicking on the Service Territory feature layer and selecting Properties.

  

  Go to Map Properties and change that coordinate system to match that of your Service Territory layer, and save your project. If working with your own project and data, ensure that your Service Territory coordinate system matches the coordinate system selected in Map Properties.

  

  See Geographic vs. Projected Coordinate Systems for more information about these map properties.

• Some ArcFM tools require the ability to assign negative Z values for below grade elevations. This spatial reference must contain a vertical coordinate system with a direction of positive up and a resolution that defines a minimum Z value with negative values.

• Later, in the Stage the Utility Network step, the Service Territory feature layer is copied into the new UN feature dataset. During the Enable Branch Versioning step, M and Z-enabled, and editor tracking enabled settings are applied, as well as the creation of global IDs.
