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.

  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. 单击关闭
  5. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.
