Evaluating vertex counts

The Evaluate Vertex Count check evaluates a feature to see if its vertex count is within specified parameters. For example, if data is imported from coverages, you can find all features with the 500 vertex limit maximum and merge them with adjacent features.

The check can be run on an entire feature class, a subtype, or a set of features selected using a SQL query. Features containing a number of vertices that fall within a specified range are returned.

Once you have defined the criteria for the check, you can configure the notes and a severity rating. The notes allow you to provide a more specific description for the feature that has been written to the Reviewer table and are copied to the Notes field in the Reviewer table. The severity rating allows you to indicate how important the results from a check are in terms of your quality assurance/quality control processes. The lower the number, the greater the priority the check's results have.

Pasos:

1. Start ArcMap.
   Sugerencia:

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

2. On the main menu, click Customize > Toolbars > Data Reviewer.
3. Click the Select Data Check drop-down arrow on the Data Reviewer toolbar, click the plus sign (+) next to Spatial Parameter Evaluation Checks, then click Evaluate Vertex Count Check.

   The Evaluate Vertex Count Check Properties dialog box appears.
4. If necessary, type a unique name for the check in the Check Title text box.
   Nota:

   The check title can be used to describe the conditions you are looking for with the check. This is useful when you have multiple instances of the same check to validate the same feature classes or tables but with different validation parameters.

5. Click the Feature Class/Subtype drop-down arrow to choose the feature class and subtype on which to run the check.
6. To run the check on the entire feature class and save this setting, check the Always Run on Full Database check box.
7. To run the check on specific features in a feature class, click SQL to construct a SQL query.
8. Click the Operation drop-down arrow and choose an operation to use to determine the vertex count threshold.
   • Less than—The number of vertices is less than the value specified.
   • Less than or equal—The number of vertices is equal to or less than the value specified.
   • Greater than—The number of vertices is greater than the value specified.
   • Greater than or equal—The number of vertices is equal to or greater than the value specified.
   • Not equal to—The number of vertices is not equal to the value specified.
   • Equal to—The number of vertices is equal to the value specified.
   • In Between (Including Bounds)—The number of vertices is between or equal to the values specified in the Lower Bound (minimum) and Upper Bound (maximum) text boxes.
   • In Between (Not Including Bounds)—The number of vertices is between the values specified in the Lower Bound (minimum) and Upper Bound (maximum) text boxes.
   • Not In Between (Including Bounds)—The number of vertices is equal to or not between the values specified in the Lower Bound (minimum) and Upper Bound (maximum) text boxes.
   • Not In Between (Not Including Bounds)—The number of vertices is not between the values specified in the Lower Bound (minimum) and Upper Bound (maximum) text boxes.

   The operation text box appears. If you choose an operation with bounding values, Lower Bound and Upper Bound text boxes appear.

9. Type a value in the operation text box.

   If you choose an operation with bounding values, you must indicate two values: one each for the minimum and maximum ranges of the tolerance.

10. If necessary, type descriptive text for the check results in the Notes text box in the Reviewer Remarks area.
11. If necessary, click the Severity drop-down arrow and choose a value that indicates the priority of the check's results in the Reviewer Remarks area.
12. Click OK.
13. Click the Run Data Check button on the Data Reviewer toolbar.

    The Features to Validate dialog box appears.
14. Choose an option in the Features to Validate area.
    • Selection Set—The check is run on the features that are currently selected in the map.
    • Current Extent—The check is run on the current map extent, which is controlled by the map scale.
    • Definition Query—The check is run on the features that are displayed based on definition queries that have been created for the feature class.
    • Full Database—The check is run on all the features in the feature class.
15. To run the check only on features that have been edited in a versioned workspace, check the Changed Features Only check box.
    Nota:

    The Changed Features Only option is available only for a versioned database.

16. Click OK.
