Finding null features (Defense Mapping)

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.

手順:

1. Start ArcMap.
2. If necessary, load data in the map.
3. On the main menu, click Customize → Toolbars → Production Editing.
4. Add the Null Feature Remover tool by doing the following:
   1. Click Customize → Customize Mode on the main menu.

      The Customize dialog box appears.

   2. Click the Commands tab.
   3. In the Categories list, click Production Editing.
   4. Click and drag Null Feature Remover to a toolbar.
   5. [閉じる] をクリックします。
5. Click the Production Start Editing button on the Production Editing toolbar.
   注意:

   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.

   ヒント:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Show/Hide Attributes button on the Manage Features window.

6. Click Null Feature Remover.

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

7. [OK] をクリックします。
