Add Trace Configuration (Trace Network)

Summary

Creates a named trace configuration in the trace network.

Named trace configurations allow you to configure and store the properties of complex traces for reuse and sharing. Named trace configurations created in a utility network can be consumed in ArcGIS Pro using the Trace tool or the Named Configurations tab in the Trace pane. When working in an enterprise deployment, these can also be shared through a web map and consumed by web and field apps.

  • Unchecked—Traversability barrier features will not be included in the trace results.
Boolean
Validate Consistency
(Optional)

Specifies whether an error will be returned if dirty areas are encountered in any of the traversed features. This is the only way to guarantee a trace is passing through features with consistent status in the network. To remove dirty areas, validate the network topology.

  • Unchecked—Features that have indeterminate or uninitialized flow direction will not be traced. This is the default.

Boolean
Condition Barriers
(Optional)

Sets a traversability barrier condition on features based on a comparison to a network attribute. A condition barrier uses a network attribute, an operator and a type, and an attribute value. For example, stop a trace when a feature has the Code attribute equal to the specific value of ArtificialPath. When a feature meets this condition, the trace stops. If you're using more than one attribute, you can use the Combine Using component to define an And or an Or condition.

Condition barrier components are as follows:

  • Name—Filter by any network attribute defined in the system.
  • Operator—Choose from a number of operators.
  • Type—Choose a specific value or network attribute from the value specified in the Name component.
  • Value—Provide a specific value for the input attribute type that would cause termination based on the operator value.
  • Combine using—Set this value if you have multiple attributes to add. You can combine them using an And or an Or condition.

Operator components are as follows:

  • Does not equal—The attribute is not equal to the value.
  • Is greater than—The attribute is greater than the value.
  • Is greater than or equal to—The attribute is greater than or equal to the value.
  • Is less than—The attribute is less than the value.
  • Is less than or equal to—The attribute is less than or equal to the value.

  • Specific valueFilter by a specific value.
  • Network attributeFilter by a network attribute.
  • AndCombine the condition barriers.
  • OrUse if either condition barrier is met.
Value Table
Function Barriers
(Optional)

Sets a traversability barrier on features based on a function. Function barriers can be used, for example, to restrict how far the trace travels from the starting point or to set a maximum value to stop a trace. For example, the length of each line traveled is added to the total distance traveled so far. When the total length traveled reaches the value specified, the trace stops.

Function barrier components are as follows:

  • Function—Choose from a number of calculation functions.
  • Attribute—Filter by any network attribute defined in the system.
  • Operator—Choose from a number of operators.
  • Value—Provide a specific value for the input attribute type that, if discovered, will cause the termination.
  • Use Local Values—Calculate values in each direction as opposed to an overall global value. For example, a function barrier calculates the sum of shape length in which the trace terminates if the value is greater than or equal to 4. In the global case, after you have traversed two edges with a value of 2, you have already reached a shape length sum of 4, so the trace stops. If local values are used, the local values along each path change, and the trace continues.

Function components are as follows:

  • Minimum—The minimum of the input values.
  • Maximum—The maximum of the input values.
  • Add—The sum of the input values.
  • Average—The average of the input values.
  • Count—The number of features.
  • Subtract—The difference between the input values.

For example, you have a starting point feature with a value of 20. The next feature has a value of 30. If you use the minimum function, the result is 20, maximum is 30, add is 50, average is 25, count is 2, and subtract is -10.

Operator components are as follows:

  • Is equal to—The attribute is equal to the value.
  • Does not equal—The attribute is not equal to the value.
  • Is greater than—The attribute is greater than the value.
  • Is greater than or equal to—The attribute is greater than or equal to the value.
  • Is less than—The attribute is less than the value.
  • Is less than or equal to—The attribute is less than or equal to the value.

Use Local Values components are as follows:

  • Checked—Local values will be used.
  • Unchecked—Global values will be used. This is the default.

  • AverageThe average of the input values.
  • CountThe number of features.
  • MaxThe maximum of the input values.
  • MinThe minimum of the input values.
  • AddThe sum of the values.
  • SubtractThe difference between the values.
  • Is equal toThe attribute is equal to the value.
  • Does not equalThe attribute is not equal to the value.
  • Is greater thanThe attribute is greater than the value.
  • Is greater than or equal toThe attribute is greater than or equal to the value.
  • Is less thanThe attribute is less than the value.The attribute is less than the value.
  • Is less than or equal toThe attribute is less than or equal to the value.
Value Table
Apply Traversability To
(Optional)

Specifies whether traversability will be applied to junctions, edges, or both. For example, in a network of recreational trails, if a condition barrier is defined to stop a trace if a surfacetype attribute contains a value of gravel and the traversability scope is set to junctions only, the trace will not stop even if it encounters an edge feature with this value in the surfacetype field, because the surfacetype attribute is only applicable to edges. In other words, this parameter indicates to the trace whether to ignore junctions, ignore edges, or include both junctions and edges in the trace.

  • Both junctions and edgesTraversability will be applied to both junctions and edges. This is the default.
  • Junctions onlyTraversability will be applied to junctions only.
  • Edges onlyTraversability will be applied to edges only.
String

  • Filter Name—Filter the function results by attribute name.
  • Filter Operator—Choose from a number of operators.
  • Filter Type—Choose from a number of filter types.
  • Filter Value—Provide a specific value for the input filter attribute.

Function component options are as follows:

  • Min—The minimum of the input values.
  • Max—The maximum of the input values.
  • Add—The sum of the input values.
  • Average—The average of the input values.
  • Count—The number of features.
  • Subtract—The difference between the input values.

For example, a starting point feature has a value of 20. The next feature has a value of 30. If you're using the Min function, the result is 20. Max is 30, Add is 50, Average is 25, Count is 2, and Subtract is -10.
