Create a template for an LRS length data product

Available with Location Referencing license.

To create linear referencing system (LRS) data products, you must create an LRS data template first; then use the template as an input to the Generate LRS Data Product tool.

An LRS length data product is used to calculate length of routes based on their characteristics. The following table is an example of an LRS length data product that computes length of pipes in different materials summarized by line name:

• Summary field: Pipeline Name
• Length fields: Steel, Plastic, Cast/Wrought Iron, Ductile Iron, Copper, and Other

Other types of LRS length data products that you can configure include the following:

• Length of types of pipe systems, such as on-shore transmission, on-shore gathering, and so on, summarized by installation year
• Length of leak report summarized by pipeline name and status code
• Length of categories of pipe diameters and pipe materials summarized by pipe systems

In this workflow, you'll learn how create a template to produce an LRS length data product similar to the one shown in the table above.

Choose an LRS data product type

The LRS length data product is the only type of product currently supported and it is the default selection in the Choose an LRS data product type pane of the LRS Data Template wizard.

1. Start ArcGIS Pro and open a project with LRS data in the map.
2. On the Location Referencing tab, in the LRS Data Products group, click LRS Data Template .

   The Choose an LRS data product type pane of the LRS Data Template wizard appears and the default Data Product Type value is Length.

3. Click Next.

   The Set template properties pane appears.

Set template properties

Once a product type is specified, you can provide template properties.

To set the template properties, complete the following steps:

1. Provide a template name.

   By default, the template is saved in the project folder. Optionally, browse to a different location, provide a name for the template, and click OK.

2. Click the Network drop-down arrow and choose a network.

   This network is used to calculate the length of the routes.

3. Optionally, provide a description.

   

4. Optionally, click Preview to open the canvas.

   The canvas formats the information provided in the wizard.

   

5. Click Next.

Set template summary fields

The next stage in producing the LRS data template is to select a summary layer and summary fields. The LRS length data product is summarized based on unique values in the summary layer. You can configure multiple summary layers and summary fields. The summary layers are arranged and divided by levels based on their spatial relationships.

For this example, you can configure a pipe system layer as level one, and a pipeline layer as level two. The LRS length data product summarizes the length of each pipeline in each pipe system.

This is optional. If you don't want to add summary fields to the template, click Next to proceed.

To set the template summary fields, complete the following steps:

1. Click Add to add a summary level.
2. Click the Summary Layer drop-down arrow and choose a summary layer.

   This layer can be a polygon feature class, a line event registered to the network specified in the second pane, or the network itself. This layer must be in the same geodatabase and have the same projection as the specified network.

   For this example, Engineering Network is the summary layer for the first level.

3. Click the Field drop-down arrow and choose a summary field.

   For this example, Line Name is the summary field for the Engineering Network.

   Once a summary field is chosen, the Display Value Map section shows the unique values in the summary field. You can edit the Display Value column in the table. The LRS length data product only calculates route length for values in the Display Value Map section.

   

4. Provide a name for the summary level in the Name in Table text box.

   For this example, the level name is Pipeline Name.

5. Optionally, click the Filter Expression drop-down arrow and provide an expression to filter display values in the Display Value Map section.

   For this example, the pipelines that are gathering field pipes are chosen. Only the length of the routes in these pipelines will be calculated.

   

   

6. If you're adding multiple summary levels, repeat the previous steps for each level.
7. Click Next.

Set template length fields

After selecting the summary layer, the next step is to add the length fields. The length fields form the columns that show the length of routes in the LRS length data product.

There are two options to configure length fields: Single Value and Unique Values. You can configure length fields one by one using the Single Value option and applying a filter to create categories, or you can use the Unique Values option to configure all the unique values needed as individual length fields.

For this example, Single Value is used to calculate the length of pipes in different materials because the data has more than one unique value that will be combined as one category. For example, the Steel field is a composite of the Bare Steel and Coated Steel fields. You'll configure them as one length field instead of individual fields.

To set template length fields, complete the following steps:

1. Click Add to add a length field.
2. Click the Length Layer drop-down arrow and choose a length layer.

   This layer can be a line event registered to the network specified in the second pane, or the network itself. This layer must be in the same geodatabase and have the same projection as the selected network.

   For this example, line event Gathering Field Pipe is the first length layer.

3. Click the Selection Method drop-down arrow and choose a selection method.
   • Single Value—Add a single length field.
   • Unique Values—Add multiple unique values for a selected length field and each unique value becomes an individual field. This option only appears when a length layer is provided without a name or filter.

   If you chose Single Value, skip step 4. For this example, Single Value is used as the selection method with customized filters applied to the length field and the example continues at step 5.

4. If you chose Unique Values, choose a field in the length layer from the pop-up window that appears and do the following:
   1. Choose the unique values by clicking the check boxes next to the values.

      

   2. Optionally, change the name for each selected unique value.

      The name becomes the name for the length field when the unique values are added to the wizard.

   3. Click Add to add the selected unique values as length fields.

      Each length field automatically has Single Value as the selection method, and a filter expression corresponding to the unique values.

      

      Note:

      The Unique Values option also honors values in coded value domains and subtypes.

5. Provide a name for this length field or update the existing names by clicking each cell.

   For this example, Steel is the name for the first length field.

6. Optionally, click the Filter Expression drop-down arrow and provide an expression to filter the length fields.

   For this example, because the template is used to calculate length of pipes in different materials, the length fields are the unique values in the Material field. The first length field is named Steel, and a filter is applied to the Material field to select values that correspond to the steel category, such as bare steel and coated steel.

   

7. If you're adding multiple length fields, repeat the previous steps for each field.

   For this example, the additional length fields are Plastic, Cast/Wrought Iron, Ductile Iron , Copper, and Other.

   

   

8. Click Finish to save the template.

Note:

To view or edit an existing template, click the folder next to Template. You can choose a template from the default project folder location or browse to other locations.

You can use this template in the Generate LRS Data Product tool.
