Classifying a linear asset

You classify a linear asset in much the same way that you classify a nonlinear asset. The key difference is that the values for linear asset attributes can change over the span of a linear asset.

Before you begin

Map out a classification hierarchy. For example, if you are classifying roads, you can have a Roads classification that has attributes that apply to all roads. You can then configure child classifications for road classes whose attributes are specific to each child class. Creating a classification hierarchy can ensure that only those attributes that are important to each asset class are applied. Use domains, which are predefined lists of values, to enhance the quality of data by restricting options and removing the possibility of data entry errors. With table domains, you can access data directly from a table column, making domain values dynamic.

Procedure

  1. In the Assets application, select the asset that you want to classify.
  2. In the Specifications tab, select the Detail menu for the Classification field and either:
    • Select Classify if the classification you want to use already exists.
    • Select Go To Classifications, to create a classification and then return with the value.
  3. Click New Row to create an attribute and add values, including start and end measures.
  4. Repeat the previous step to create all of the attributes required to properly classify the asset.
    When you classify a road, for example, you can add a different County attribute for each county that is traversed by the road, and a different Area attribute for urban and rural sections of the road.
  5. Click Save Asset.

Example

This example classifies a road. You create a classification called Road and select this classification. Create an attribute called Alias because most roads are known by other names by maintenance teams and external agencies. The road is called the Memorial Highway from mile 10 to 20, so specify this as the value for attribute Alias, and enter 10 as the start measure and 20 as the end measure. The road is known as the Northeast Corridor from mile 15 to 40, so click New Row, specify Alias as the attribute, and repeat the process, entering Northeast Corridor as the value and 15 and 40 as the start and end measures respectively. These entries overlap which is acceptable. If the attribute is defined as Continuous (in the Classifications application), the overlap is identified when you run the Gaps and Overlap report.
