Generating a QC cell from the NIS

After you have compiled new data, you may still need to validate the data you have compiled before you define a specific S-57 product in the Product Library. You may also need to validate a specific subset of data contained in a product. To validate this type of data, you can generate a quality control (QC) S-57 cell using Generate QC Cell.

Generate QC Cell allows you to choose a custom extent and limits extraction to a single scale. It is different in that respect than other tools that export to S-57 from the geodatabase. Generate QC cell validates the accuracy of the attribution and the topology over an extent that is less than or otherwise not equal to the extent of a specific product.

注：

Any cell produced using Generate QC Cell is for quality control purposes only and cannot be used for navigation. Navigational products must be created using the Export Geodatabase to S-57 geoprocessing tool, or the Export Nautical Product wizard.

Setting up the environment

If you use versioning, you can choose which version to use for generating the QC cell.

1. 启动 ArcMap。
2. On the main menu, click Customize > Toolbars > Nautical.
3. Add the Nautical feature dataset from your NIS to the Table Of Contents window.
4. If necessary, change to an edit version by doing the following:
   1. Click the List By Source button at the top of the Table Of Contents window.
   2. Right-click the version workspace and click Change Version.

      The Change Version dialog box appears.

   3. Choose the edit version.
   4. Click OK.

Generating the QC cell

Generate QC Cell contains two methods: Selected Polygon Feature and Graphic. Both options limit the contents of the output cell by the chosen AOI and the specific scale of data requested. If you need to validate a specific product, use the Validate Sample S-57 geoprocessing tool.

1. Choose the method you want to use.

   Create a QC cell from a polygon	Click the Select Features button on the Tools toolbar, select the polygon you want to use, click the Generate QC Cell drop-down menu on the Nautical toolbar, and click Generate QC Cell (Selected Polygon Feature).
   Create a QC cell by defining an extent	Click the Generate QC Cell drop-down menu on the Nautical toolbar, click Generate QC Cell (Graphic), and define the extent of your cell by clicking and dragging.

   The Generate QC Cell dialog box appears.

2. Type the scale to extract from the NIS in the Extract Scale text box.
3. Type a name for the cell in the Cell Name text box.
4. For the Output Folder parameter, browse to the file location where you want to save the QC cell.
5. 单击确定。

The cell is created in the output location.
