Deleting duplicate features

获得 Production Mapping 许可后可用。

The Production Delete Duplicate Features tool allows you to delete duplicate features in instances where multiple features are within the same location.

Each selected feature is evaluated and compared to each of the other features of the same geometry type. If the geometries are identical, all but one of the features will be deleted.

1. 启动 ArcMap。
2. 如有必要，可在地图中加载数据。
3. 在主菜单上，单击自定义 > 工具条 > 生产编辑。
4. 在主菜单上，单击自定义 > 工具条 > 高级生产编辑。
5. 单击生产编辑工具条上的启动生产编辑按钮 。

   注：

   使用启动生产编辑工具开始编辑会话时，系统将自动显示管理要素和创建属性、更新属性或元数据属性窗口。

   提示：

   如果开始编辑会话时未显示创建属性、更新属性或元数据属性窗口，请单击管理要素窗口上的显示/隐藏属性按钮 。

6. Click the Select Features button on the Tools toolbar and select at least two features of the same feature type.
7. Click the Production Delete Duplicate Features button on the Production Editing Advanced toolbar.

   The Production Delete Duplicates dialog box appears.

   

8. Choose an option for comparing the features.
   • Compare by feature class, subtype, and geometry—This option deletes features that have equal geometries and are part of the same feature class and subtype, regardless of whether other attributes are equal.
   • Compare by feature class, attributes, and geometry—This option deletes features that have equal geometries that are part of the same feature class with identical attribute values; that is, only the ObjectIDs are different.
   • Compare by geometry only—This option deletes features that have equal geometries, regardless of the parent feature class.
9. Click the Delete feature with drop-down arrow and choose an option.
   • Highest OID—The feature with the larger ObjectID value is deleted.
   • Lowest OID—The feature with the lowest ObjectID value is deleted.
10. Click Apply.

    A message appears and displays the number of features deleted.

11. Click Cancel to close the Delete Duplicates dialog box.
