Finding null features

Importing data from other sources can introduce geometry that ArcGIS does not support, such as polygons with areas smaller than the precision of the geodatabase. The Null Feature Remover command checks the length and area fields, where applicable, of feature classes in the table of contents. If the field is populated with a zero or null value, that feature is removed from the database.

Schritte:

1. Start ArcMap.
   Tipp:

   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. If necessary, load data in the map.
3. On the main menu, click Customize > Toolbars > Production Editing.
4. On the main menu, click Customize > Toolbars > Production Editing Advanced.
5. Click the Production Start Editing button on the Production Editing toolbar.
   Hinweis:

   The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.

   Tipp:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Link Feature Manager To Attributes Window button on the Manage Features window.

6. On the Production Editing Advanced toolbar, click More Editing Tools > Null Feature Remover.

   A message box appears that indicates how many features were deleted.

7. Click OK.
