Available with ArcGIS Pro Standard and Data Reviewer licenses.
Summary
The Find Event Overlaps check finds linear-referenced events that have overlaps with events of the same category in the same route or across multiple routes. For example, it will find two speed limit events overlapping with two different speed limit values.
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:
| Validation | Constraint | |
|---|---|---|
Reviewer batch job | Attribute (validation) rule | No |
Yes | Yes (ArcGIS Pro 3.1 and ArcGIS Enterprise 11.1 or later) | |
Overview
The Find Event Overlaps check identifies event overlaps that can impact analysis and asset management workflows.
Example
The following image illustrates linear events (in red) that overlap other events in the same route and across multiple routes:
Syntax
| Parameter | Required | Explanation | Workflow |
|---|---|---|---|
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 measure value that describes the starting location for a linear event feature. For point event features, this is the Measure parameter and describes the location of the point. The field must be a numeric data type. | Validation |
Event Properties/To Measure | Yes | The name of the field that contains the measure value that describes the end location 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 an overlap on other events. Events within this tolerance are considered valid. 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. | Validation |
Notes
Keep the following in mind when using the check:
- This check supports validation of events stored in line feature classes.
- 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.
- 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.
