Trace

Summary

Returns selected features based on connectivity or traversability from the specified starting points.

Utility network tracing capabilities allow you to analyze the paths in your network. This tool runs a trace that returns features based on connectivity or traversability from the specified starting points. Traversability refers to paths established by connected or associated features that also meet configuration requirements.

Results from a trace operation are returned as a selection set of the appropriate network features. The resulting selection set of a trace can then be propagated to another map, propagated to a diagram view of the network, or used as input to another tool or trace.

Usage

  • The network topology must be enabled. Since the Trace tool relies on the network topology, the results of a trace are not guaranteed to be accurate if dirty areas are traced. The network topology for the area to be traced must be validated to reflect the most recent edits or updates made to the network.

  • The input utility network must be a utility network service.

  • When executing a subnetwork-based trace using the Trace tool via Python, the Subnetwork Trace Configuration of the subnetwork definition is not used for the input Tier and must be manually specified.

Utility Network; Utility Network Layer
trace_type

Specifies the type of trace to execute.

  • CONNECTED A connected trace begins at one or more starting points and spans outward along connected features. This is the default.
  • SUBNETWORK A subnetwork trace begins at one or more starting points and spans outward to encompass the extent of the subnetwork.
  • SUBNETWORK_CONTROLLERSA subnetwork controllers trace locates sources and sinks on subnetwork controllers associated with a subnetwork.
  • UPSTREAMAn upstream trace discovers features upstream from a location in the network.
  • DOWNSTREAMA downstream trace discovers features downstream from a location in the network.
  • LOOPS Loops are areas of the network where flow direction is ambiguous. A loops trace spans outward from the starting point based on connectivity.
  • SHORTEST_PATHA shortest path trace identifies the shortest path between two starting points.
  • ISOLATIONAn isolation trace discovers features that isolate an area of a network.
String
starting_points
(Optional)

A point feature class containing one or more features that represent the starting points of the trace. This feature class must have a specific format, including fields that store the asset group, asset type, terminal id, and percent along edge of the starting point. To view the specific format, create starting points using the Starting Points tool in the Trace Locations pane and view the schema of the UN_Temp_Starting_Points feature class stored in your default geodatabase.

Feature Layer
barriers
(Optional)

A feature class containing one or more features that represent the barriers of the trace that prevents the trace from traversing beyond that point. This feature class must have a specific format, including fields that store the asset group, asset type, and terminal id. To view the specific format, create starting points using the Barriers tool in the Trace Locations pane and view the schema of the UN_Temp_Barriers feature class stored in your default geodatabase.

Feature Layer
domain_network
(Optional)

The name of the domain network where the trace will be run. This parameter is required when running the subnetwork, subnetwork controllers, upstream, and downstream trace types.

String
tier
(Optional)

The name of the tier to start the trace. This parameter is required when running the subnetwork, subnetwork controllers, upstream, and downstream trace types.

String
target_tier
(Optional)

The name of the target tier to which the input tier flows. If this parameter is missing for upstream and downstream traces, those traces will stop when they reach the boundary of the starting subnetwork. This parameter can be used to allow these traces to continue either farther up or farther down the hierarchy.

String
subnetwork_name
(Optional)

The name of the subnetwork where the trace will be run. This parameter can be used when running a subnetwork trace type. If a subnetwork name is specified, the starting_points parameter is not required.

String
shortest_path_network_attribute_name
(Optional)

The network attribute used to calculate the shortest path. When running a shortest path trace type, the shortest path is calculated using a numeric network attribute such as shape length. Cost and distance based paths can both be achieved. This parameter is required when running a shortest path trace.

  • EXCLUDE_BARRIERSTraversability barrier features will not be included in the trace results.
Boolean
validate_consistency
(Optional)

Specifies whether a warning will be returned if dirty areas are encountered for 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, the network topology should be validated.

  • VALIDATE_CONSISTENCYA warning will be returned if dirty areas are encountered for any of the traversed features.
  • DO_NOT_VALIDATE_CONSISTENCYA warning will not be returned if dirty areas are encountered for any of the traversed features. This is the default.
Boolean
condition_barriers
[[Name, Operator, Type, Value, Combine Using],...]
(Optional)

Sets a traversability barrier condition on features based on a comparison to a network attribute or check for a category string. 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 attribute Device Status equal to the specific value of Open. When a feature meets this condition, the trace stops. If you're using more than one attribute, you can use the Combine using parameter to define an And or an Or condition.

Condition barrier components are as follows:

  • Operator—Choose from a number of different operators.
  • Type—Choose a specific value or network attribute from the value that is specified in the name parameter.
  • 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.

The condition barriers operator value options are as follows:

  • 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.
  • IS_LESS_THAN_OR_EQUAL_TOThe attribute is less than or equal to the value.
  • INCLUDES_THE_VALUESA bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value).
  • DOES_NOT_INCLUDE_THE_VALUESA bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value).
  • INCLUDES_ANYA bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True).
  • DOES_NOT_INCLUDE_ANYA bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False).

The condition barriers Type value options are as follows:

  • SPECIFIC_VALUEFilter by a specific value.
  • NETWORK_ATTRIBUTEFilter by a network attribute.

The condition barriers Combine Using value options are as follows:

  • ANDCombine the condition barriers.
  • ORUse if either condition barrier is met.
Value Table
function_barriers
[[Function, Attribute, Operator, Value, Use Local Values],...]
(Optional)

Sets a traversability barrier on features based on a function. Function barriers can be used to do such things as restrict how far the trace travels from the starting point, or 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 different calculation functions.
  • Attribute—Filter by any network attribute defined in the system.
  • Operator—Choose from a number of different 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 that is calculating the sum of Shape length where 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 will 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.

The function barrier function value options are as follows:

  • 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. Subnetwork controllers and loops trace types do not support the subtract function.

The function barrier operator value options are as follows:

  • 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.
  • IS_LESS_THAN_OR_EQUAL_TOThe attribute is less than or equal to the value.
  • INCLUDES_THE_VALUESA bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value).
  • DOES_NOT_INCLUDE_THE_VALUESA bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value).
  • INCLUDES_ANYA bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True).
  • DOES_NOT_INCLUDE_ANYA bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False).

The function barrier Use Local Values options are as follows:

  • TRUEUse local values.
  • FALSEUse global values. This is the default.
Value Table
traversability_scope
(Optional)

The type of traversability to enforce. Traversability scope dictates whether traversability is enforced at junctions, edges, or both. For example, if a condition barrier is defined to stop the trace if Device Status is equal to Open and traversability scope is set to edges only, then even if the trace encounters an open device, the trace would not stop because Device Status is only applicable to junctions. In other words, this parameter indicates to the trace whether to ignore junctions, edges, or both.

  • BOTH_JUNCTIONS_AND_EDGESApply traversability to both junctions and edges. This is the default.
  • JUNCTIONS_ONLYApply traversability to only junctions.
  • EDGES_ONLYApply traversability to only edges.
String
filter_barriers
[[Name, Operator, Type, Value, Combine Using],...]
(Optional)

Specifies when a trace should stop for a specific category or network attribute. For example, stop a trace at features that have a life cycle status attribute that is equal to a certain value. This parameter is used to set a terminator based on a value of a network attribute that is defined in the system. If using more than one attribute, you can use the Combine Using option to define an And or an Or condition.

Filter barrier components are as follows:

  • Name—Choose to filter by category or any network attribute defined in the system.
  • Operator—Choose from a number of different operators.
  • Type—Choose a specific value or network attribute from the value that is specified in the name parameter.
  • Value—Provide a specific value of 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 choose to combine them using an And or an Or condition.

  • DOES NOT INCLUDE_THE_VALUESA bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value).
  • INCLUDES_ANYA bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True).
  • DOES_NOT_INLCUDE_ANYA bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False).

Filter function barriers components are as follows:

  • Function—Choose from a number of different calculation functions.
  • Attribute—Choose to filter by any network attribute defined in the system.
  • Operator—Choose from a number of different operators.
  • Value—Provide a specific value for the input attribute type that, if discovered, will cause the termination.
  • Use Local Values—Calculates values in each direction as opposed to an overall global value. For example, a function barrier that is calculating the sum of Shape length where 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 will 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, or the trace continues.

The filter function barriers function value options are as follows:

  • AVERAGEThe average of the input values.
  • COUNTThe number of features.
  • MAXThe maximum of the input values.

The filter function barriers Use Local Values options are as follows:

  • TRUEUse local values.
  • FALSEUse global values. This is the default.
Value Table
filter_scope
(Optional)

Specifies whether the filter for a specific category will be enforced at junctions, edges, or both. For example, if a filter barrier is defined to stop the trace if Device Status is equal to Open and traversability scope is set to edges only, then even if the trace encounters an open device, the trace will not stop because Device Status is only applicable to junctions. In other words, this parameter indicates to the trace whether to ignore junctions, edges, or both.

  • BOTH_JUNCTIONS_AND_EDGESThe filter will be applied to both junctions and edges. This is the default.
  • JUNCTIONS_ONLYThe filter will be applied to junctions only.
  • EDGES_ONLYThe filter will be applied to edges only.
String
filter_bitset_network_attribute_name
(Optional)

The name of the network attribute that can be used to filter by bitset. This parameter is only applicable to upstream, downstream, and loops trace types. This parameter can be used to add special logic during a trace so the trace is more reflective of real world scenarios. For example, for a loops trace, the Phases current network attribute can determine if the loop is a true electrical loop (the same phase is energized all around the loop, that is, A) and return only real electrical loops for the trace results. An example for an upstream trace is when tracing an electric distribution network, specify a Phases current network attribute, and the trace results will only include valid paths that are the specified in the network attribute, not all paths.

String
filter_nearest
(Optional)

Specifies whether the k-nearest neighbors algorithm will be used to return a number of features of a certain type within a given distance. When this parameter is used, you can specify a count and a cost as well as a collection of categories, an asset type, or both.

  • FILTER_BY_NEARESTThe k-nearest neighbors algorithm will be used to return a number of features as specified in the nearest_count, nearest_cost_network_attribute, nearest_categories, or nearest_assets parameter.
  • DO_NOT_FILTERThe k-nearest neighbors algorithm will not be used to filter results. This is the default.
Boolean
nearest_count
(Optional)

Specify the number of features to be returned when filter_nearest is True.

Long
nearest_cost_network_attribute
(Optional)

The numeric network attribute that will be used to calculate nearness, cost, or distance when filter_nearest is True—for example, Shape length.

String
nearest_categories
[nearest_categories,...]
(Optional)

The categories that will be returned when filter_nearest is True—for example, Protective.

String
nearest_assets
[nearest_assets,...]
(Optional)

The asset groups and asset types that will be returned when filter_nearest is True—for example, ElectricDistributionDevice/Transformer/Step Down.

String
functions

(Optional)

Applies a calculation function to the trace results.

Functions components are as follows:

  • Function—Choose from a number of different calculation functions.
  • Attribute—Filter by any network attribute defined in the system.
  • Filter Name—Filter the function results by attribute name.
  • Filter Operator—Choose from a number of different operators.
  • Filter Type—Choose from a number of different filter types.
  • Filter Value—Provide a specific value for the input filter attribute.

The functions Function value options are as follows:

  • 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.Subnetwork controllers and loops trace types do not support the subtract function.

For example, there is a starting point feature with a value of 20. The next feature has a value of 30. If you are using the MINIMUM function, the result is 20. MAXIMUM is 30, ADD is 50, AVERAGE is 25, COUNT is 2, and SUBTRACT is -10.

The Filter Operator value options are:

  • 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.
  • IS_LESS_THAN_OR_EQUAL_TOThe attribute is less than or equal to the value.
  • INCLUDES_THE_VALUESA bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value).
  • DOES_NOT_INCLUDE_THE_VALUESA bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value).
  • INCLUDES_ANYA bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True).
  • DOES_NOT_INCLUDE_ANYA bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False).

  • SPECIFIC_VALUEFilter by a specific value.
  • NETWORK_ATTRIBUTEFilter by a network attribute.
Value Table
propagators
[[Attribute, Substitution Attribute, Function, Operator, Value],...]
(Optional)

Specifies the network attributes to propagate as well as how that propagation should occur during a trace. Propagated class attributes denote the key values on subnetwork controllers that are disseminated to the rest of the features in the subnetwork. For example, in an electric distribution model, you can propagate the phase value.

Propagators components are as follows:

  • Attribute—Filter by any network attribute defined in the system.
  • Substitution Attribute—Use a substituted value instead of bitset network attribute values. Substitutions are encoded based on the number of bits in the network attribute being propagated. A substitution is a mapping of each bit in phase to another bit. For example, for Phase AC, one substitution could map bit A to B, and bit C to null. In this example, the substitution for 1010 (Phase AC) is 0000-0010-0000-0000 (512). The substitution captures the mapping so you know that Phase A was mapped to B, and Phase C was mapped to null and not the other way around (that is, Phase A was not mapped to null and Phase C was not mapped to B).
  • Function—Choose from a number of calculation functions.
  • Operator—Choose from a number of operators.
  • Value—Provide a specific value for the input attribute type that would cause termination based on the operator value.

The propagators function value options are as follows:

  • PROPAGATED_BITWISE_ANDCompare the values from one feature to the next.
  • PROPAGATED_MINGet the minimum value.
  • PROPAGATED_MAXGet the maximum value.

  • INCLUDES_THE_VALUESA bitwise AND operation where all bits in the value are present in the attribute (bitwise AND == value).
  • DOES_NOT_INCLUDE_THE_VALUESA bitwise AND operation where not all of the bits in the value are present in the attribute (bitwise AND != value).
  • INCLUDES_ANYA bitwise AND operation where at least one bit in the value is present in the attribute (bitwise AND == True).
  • DOES_NOT_INCLUDE_ANYA bitwise AND operation where none of the bits in the value are present in the attribute (bitwise AND == False).

String
output_conditions
[[Name, Operator, Type, Value, Combine Using],...]
(Optional)

Specifies the types of features that will be returned based on a network attribute or category. For example, in a trace configured to filter out everything but Tap features, any traced features that do not have the Tap category assigned to them, are not included in the results. Any traced features that do are returned in the result selection set. If using more than one attribute, you can use the Combine Using option to define an And or an Or condition.

  • Operator—Choose from a number of different operators.
  • Type—Choose a specific value or network attribute from the value that is specified in the name parameter.
  • Value—Provide a specific value of the input attribute type that would cause termination based on the operator value.

The output conditionsoperator value options are as follows:

  • 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.

Note:

The isolation trace type requires ArcGIS Enterprise 10.7 or later.

Boolean
ignore_barriers_at_starting_points
(Optional)

Specifies whether dynamic barriers in the trace configuration are ignored for starting points. This may be useful when performing an upstream protective device trace and using the discovered protective devices (barriers) as starting points to find subsequent upstream protective devices.

  • IGNORE_BARRIERS_AT_STARTING_POINTSTrace will ignore barriers that are at a starting point.
  • DO_NOT_IGNORE_BARRIERS_AT_STARTING_POINTSTrace will still honor barriers that are at a starting point. This is the default.
