Available with ArcGIS Pro Standard and Data Reviewer licenses.
Summary
The Evaluate Z Values check returns features with z-values that fall within specified parameters.
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 2.9 and ArcGIS Enterprise 10.9.1 or later) |
Overview
A z-value usually indicates the elevation of a feature in relation to the ground surface. If features from a feature class should be populated with relatively similar values for elevation, you can run the Evaluate Z Values check to ensure that the elevations are within an expected range of values. You can run the check on an entire feature class, a subtype, or a set of features selected using an SQL query. Features with z-values that fall within the specified range are returned.
Syntax
Parameter | Required | Description | 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 |
Elevation Value | Yes | The operation used to decide the threshold for z-values. Any features whose elevation values match those defined in the rule are returned as an error.
More input is required if you choose an operator with upper and lower bounding values. | 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 | Yes | 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:
- A vertical coordinate system must be defined for the feature class used with this check.
- The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
- 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.
