Adding mileage fields using unique values

You can add multiple mileage fields using the unique values available in an attribute field in an event layer. As shown in the sample report below, multiple mileage fields are added using the field Surface_Type from the Surface Type event. Mileages have been reported for each surface type, such as bituminous, gravel, brick, and so on, available in the Surface Type event layer and are summarized countywise.

In this example, the process produces a mileage report similar to the one shown above. The mileages and summaries are calculated using internal event layers that are part of the LRS.
