Validating nautical topology (Maritime Charting)

Nautical topology uses geodatabase topology to ensure the data integrity of the nautical product. It has a large set of pre-configured individual topology rules, which satisfy some of the S-58 checks. For example, the topology checks ensure that land and depth areas don’t overlap one another. Nautical topology dataset exists in the ENC, AML, and IENC production databases; it is not implemented in the enterprise NIS database or Chart production database. The topology rules are based on S-57 objects. AML and IENC share objects with ENC and the same topology checks are configured for them for the shared objects.

Nautical topology must be validated to find errors for the configured rules. You may validate the nautical topology in your product using the tools on Topology toolbar as well as Validate Topology geoprocessing tool. Update Primitives also validates topology every time it is run.

步骤:

1. Start ArcMap.
2. Click the Add Data button on the Standard toolbar.
3. Navigate to the production database and add it to map.
4. On the main menu, click Customize > Toolbars > Production Editing.
5. Click the Production Start Editing button on the Production Editing toolbar.
   注:

   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.

   提示:

   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. On the main menu, click Customize > Toolbars > Topology.
7. 可使用拓扑 工具条上的工具验证部分拓扑。
   • 单击验证指定区域中的拓扑 ，然后拖出一个框框住要验证的区域。将验证处于边界框内的要素。
   • 单击验证当前范围中的拓扑 。不验证地图中当前不可见的区域。
8. 单击拓扑 工具条上的错误检查器 。
9. 您可以使用错误检查器 窗口查找错误和异常。

   要查找所有规则的错误	单击显示下拉箭头，然后单击所有规则中的错误。
   要查找特定拓扑规则的错误	单击显示下拉箭头，然后单击规则。
   要查找可见范围中的错误	选中仅搜索可见范围。
   要查找异常	选中异常，并取消选中错误。

10. 单击立即搜索。
11. 单击错误检查器 列表中的错误或者使用修复拓扑错误工具在地图上单击该错误。

    该错误将在地图上绘制为黑色。

12. 右键单击列表中或地图上的错误，然后单击其中一种可用的修复。列出的修复取决于错误类型。

    例如，要通过将重叠面合并为另一个面来修复“不能重叠”错误，可右键单击该错误，单击“合并”，然后选择错误要素要合并为哪种要素。

13. 再次验证拓扑以确保编辑内容正确无误。
