Invalid Event Measures

Available with ArcGIS Pro Standard and Data Reviewer licenses.

Summary

The Invalid Event Measures check finds linear-referenced events that contain invalid measure values on events in the same route or across multiple routes.

Supported workflows

ArcGIS Data Reviewer checks support multiple methods for implementing automated review of data. The following table identifies the supported implementation methods for this check:

Overview

The Invalid Event Measures check identifies linear referenced events that have errors that can impact analysis and asset management workflows. Events with invalid measures contain measure values outside the range of those in related route features. This includes event measures that are greater than, less than, or within a gap in a related route's measure values.

Industry scenarios

This check can be used in the following scenarios:

  • In roadway management, a speed limit event representing 55 mph needs to have the same measure value as the related route feature.
  • In roadway management, event features that contain invalid measure values adversely affect length calculations, for example, United States Department of Transportation mileage reports.
  • In pipeline management, recording the measure of protective coating applied to underground assets ensures accuracy of reporting and safety of underground features.

Subtype

No

The subtype to which the rule is applied.

Validation

Attribute

No

A query that identifies the features to which the rule is applied.

Validation

Event Properties/Route Identifier

Yes

The name of the field that contains values used to associate events to routes.

The field must be a numeric data type.

Validation

Event Properties/From Measure

Yes

The name of the field that contains the starting measure value for a point or linear event feature.

The field must be a numeric data type.

Validation

Event Properties/To Measure

Yes

The name of the field that contains the ending measure value for a linear event feature.

The field must be a numeric data type.

Validation

Event Properties/Event From Date

Yes

The name of the field that contains values that define the starting date for a point or linear event feature.

The field must be a date data type.

Validation

Event Properties/ Event To Date

Yes

The name of the field that contains values that define the ending date for a point or linear event feature.

The field must be a date data type.

Validation

Route Properties/Input Route

Yes

The input route feature to which the event is referenced.

Validation

Route Properties/Route Identifier

Yes

The name of the field that contains values used to associate events to routes.

The field must be a numeric data type.

Validation

Route Properties/Route From Date

Yes

The name of the field that contains values that define the starting date for a route.

The field must be a date data type.

Validation

Route Properties/ Route To Date

Yes

The name of the field that contains values that define the ending date for a route.

The field must be a date data type.

Validation

Measure Tolerance

No

Optional value used when finding events that have invalid measures.

The linear referencing system m-tolerance is used by default.

Validation

Name

Yes

A unique name for the rule.

This information is used to support data quality requirement traceability, automated reporting, and corrective workflows.

Validation

Description

No

A description you define of the error when a noncompliant feature is found.

This information is used to provide guidance to facilitate corrective workflows.

Validation

Severity

No

The severity of the error assigned when a noncompliant feature is found.

This value indicates the importance of the error relative to other errors. Values range from 1 to 5, with 1 being the highest priority and 5 being the lowest.

Validation

Tags

No

The tag property of the rule.

This information is used in rule authoring and management workflows to support traceability and reporting of data quality requirements.

Notes

Keep the following in mind when using the check:

  • The event's related route source feature layer must be m-enabled.
  • This check supports validation of events stored in point and line feature classes.
  • Optionally, you can define a Measure Tolerance value to use when finding events that have invalid measures. This value cannot be less than the m-tolerance value of the input route feature.

  • This check supports validation of events that are stored in an enterprise geodatabase and registered with the linear referencing system (LRS) of either ArcGIS Roads and Highways or ArcGIS Pipeline Referencing.
  • Route features must be m-enabled and registered with the LRS of either Roads and Highways or Pipeline Referencing.
  • A route identifier field (numeric data type) is required for all route and event features.
  • An attribute index on the route identifier field speeds up the dynamic segmentation process.
  • Events associated with nonmonotonic route features are not evaluated by this check. Nonmonotonic routes are routes that contain measure values that are either continuous or do not strictly increase or decrease in value.

    The Monotonicity check is used to find nonmonotonic routes that require correction.

  • Only input features with a validation status of 2 (No calculation required, validation required, no error), 3 (No calculation required, validation required, has error(s)), 6 (Calculation required, validation required, no error) or 7 (Calculation required, validation required, has error(s)) are considered during rule evaluation.
  • The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
  • Event checks are not supported in composite rule configurations.
