Validate and fix geodatabase topology

Available with Standard or Advanced license.

On the Edit tab, in the Manage Edits group, Error Inspector Error Inspector is a table viewer that enables you to search for, manage, and repair topology errors in a map. You can validate features in the current map extent or the entire topology.

Validating features in a map validates them against all topology rules defined in the source geodatabase. The errors that appear in the table are filtered by the topology rule you choose on the toolbar.

To learn more about geodatabase topology rules and predefined fixes for a specific feature type, see the following topics:

The following sections provide a basic workflow to get started validating and fixing geodatabase topology.

Validate topology

Validating features compares them against all topology rules defined in the source geodatabase. Geometry that violates a rule is marked as an error and appears in the table. The errors that appear in the table are symbolized on topology layers organized by geometry type.

Once you validate a topology, future edits are framed by a symbolized rectangular region indicating the area has not been validated. The symbolized region is created on a topology layer named Modified Areas, Dirty Areas, or a similar name.

  1. On the Edit tab, in the Manage Edits group, click Error Inspector Error Inspector.

    The Error Inspector table appears.

  2. On the toolbar, click Validate Validate Extent.

    Features in the current map are validated against all topology rules defined in the source geodatabase.

    Tip:

    Topology validation tools are also available in the Modify Features pane when you enable a geodatabase topology rule on the Edit tab.

Preview and zoom to errors

The Preview tab displays a zoomed close-up of the incorrect geometry for the error you selected in the error table.

  1. On the Edit tab, in the Manage Edits group, click Error Inspector Error Inspector.

    The Error Inspector table appears.

  2. On the toolbar, click Validate Validate Extent.

    Features in the current map are validated against all topology rules defined in the source geodatabase.

  3. On the toolbar, click the Source drop-down menu and choose a source topology rule.

    Topology errors appear in the error table like records.

  4. Click the Preview tab.
  5. In the error table, select an error by clicking the gray square next to the shape field.

    A zoomed view of the incorrect geometry appears in the viewer.

  6. On the toolbar below the viewer, click Zoom to Error Zoom to Error.

    The active map zooms to the error on the map.

View details about an error

The Details tab displays information about the feature for the error you select in the error table.

  1. On the Edit tab, in the Manage Edits group, click Error Inspector Error Inspector.

    The Error Inspector table appears.

  2. On the toolbar, click Validate Validate Extent.

    Features in the current map are validated against all topology rules defined in the source geodatabase.

  3. On the toolbar, click the Source drop-down menu and choose a source topology rule.

    Topology errors appear in the error table like records.

  4. Click the Details tab.
  5. In the error table, select an error by clicking the gray square next to the shape field.

    Information about the feature appears on the tab.

Fix an error

The Fix tab contains commands to fix the error you select in the error table.

  1. On the Edit tab, in the Manage Edits group, click Error Inspector Error Inspector.

    The Error Inspector table appears.

  2. On the toolbar, click Validate Validate Extent.

    Features in the current map are validated against all topology rules defined in the source geodatabase.

  3. On the toolbar, click the Source drop-down menu and choose a source topology rule.

    Topology errors appear in the error table like records.

  4. Click the Fix tab.
  5. In the error table, select a feature record by clicking the gray square next to the shape field.
    • To select a range of feature records, you can drag the pointer up or down across the rows, or press Shift and click the last record in the sequence.
    • To select multiple feature records, press Ctrl and click each record.

    Tools available for the selected error appear on the tab.

  6. To manage exceptions, choose one of the following:
    • Mark as Exception Mark as Exception—Removes the symbolized error on the topology layer, and the feature is ignored when you validate your edits. You can reinstate the error if you decide the feature should be modified to comply with the topology rule.
    • Clear Exception Clear Exception—Reinstates the error and symbolizes the error on the topology layer on the map.
    Note:

    Exceptions are a normal part of the data creation and update process. For example, an assessor geodatabase might include a rule that building features must not cross parcel boundaries. For a high-density housing complex or a commercial building, this might be permitted.

  7. To fix errors, do one of the following:
    • On the tab, click the appropriate command.
    • On the toolbar below the commands, click Fix Error Fix Error, select the error on the map with the pointer, and use the commands that appear on the pop-up menu.
