Different Z at Intersection

Available with ArcGIS Pro Standard and Data Reviewer licenses.

Summary

The ArcGIS Data Reviewer Different Z at Intersection check searches for intersecting polyline features with z-value differences that are larger than a specified tolerance at intersection points.

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 Different Z at Intersection check identifies features that may have different z-values, such as two feature classes that intersect in the x,y plane.

For example, a contour line and a bridge can have different elevations since the contour measures the elevation on the ground and the bridge can be significantly above the ground. In this instance, the intersection is valid, as the difference in z-values is expected. However, a road feature intersecting the bridge should have the same z-value as the bridge at the intersection; they cannot have different z-values and still have a valid intersection point.

Syntax

ParameterRequiredDescriptionWorkflow

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

Features to Compare

Yes

Input features are returned as errors based on their relationship to the features from this data source.

Valid inputs are z-enabled polyline features with horizontal and vertical datums that match the input data source.

Validation

Features to Compare Filter

No

A query that identifies the features to include in the rule, from the data source specified in the Features to Compare parameter.

Validation

Spatial Relationship

Yes

The spatial relationship to be evaluated.

Types of spatial relationships include the following:

  • Crosses—The interior of a feature from the input feature class meets the interior of a feature from the Features to Compare source at a point.
  • Touches—The boundary of a feature from the input feature class meets the boundary of a feature from the Features to Compare source. The interiors of the features do not intersect.

Validation

Z-Value Tolerance

Yes

The error condition evaluated by the rule.

This parameter defines the upper and lower bounds of the tolerance between features. Polyline features with a z-value difference within the maximum and minimum specified tolerance range at the point where they intersect are returned as an error.

The z-value tolerance can be defined in feet, U.S. feet, or meters.

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 of the error you define 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:

  • This check supports z-enabled polyline features.
  • A vertical coordinate system must be defined for the feature classes you want to use with this check.
  • The Validation Status attribute value of input features is ignored during evaluation. For example, input features with a validation status of 0 (No calculation required, no validation required, no error), 1 (No calculation required, no validation required, has error(s)),4 (Calculation required, no validation required, no error), or 5 (Calculation required, no validation required, has error(s)) are still included during rule evaluation.
  • The Attribute and Features to Compare Filter parameters are limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
  • Include the data source for the Features to Compare parameter when creating map or project packages and when sharing web layers with the Validation capability enabled.
  • The Attribute filter parameter does not support the following field types: Big Integer, Date Only, Time Only, and Timestamp Offset. If selected, the row header will turn red and will not allow the rule to save.
