Checking out a replica from the NIS

One of the benefits the Nautical Information System (NIS) database offers is that multiple-scale data can be stored in one central location. Each feature class in the NIS schema contains the field PLTS_COMP_SCALE, which identifies the compilation scale of the feature data. The Checkout Nautical Replica tool allows you to edit a subset of data from the enterprise NIS in a file geodatabase child replica. You can then synchronize these edits with the NIS using the Synchronize Changes wizard.

With the Checkout Nautical Replica tool, you can do the following:

• Select and edit a specific geographic extent, AOI, or product.
• Edit using a local file geodatabase, eliminating the potential for network latency.
• Select a scale band.
• Create a custom query.
• Reduce the need for a network connection to the NIS.

Before using the Checkout Nautical Replica tool, you need to create the template geodatabase with an ENC schema. You can then edit the data in the child replica and synchronize these edits with the NIS.

1. Start ArcMap.
2. Create a template geodatabase if you haven't created it already.
3. Make a local copy of the template geodatabase.
4. Click the Select Features button on the Tools toolbar.
5. Select the polygons you want to use.

   Remarque :

   You can use an AOI by checking the component in the Product Library window.

6. Click the Checkout Nautical Replica button on the Nautical toolbar.

   The Checkout Nautical Replica dialog box appears.

7. Click the ellipsis button (…) next to SDE Workspace.
8. Browse to and choose the NIS enterprise workspace you want to replicate.
9. Cliquez sur Ajouter.
10. Click the Select Version drop-down arrow to define the version.

    If a list of versions is not available, close the tool and create a new version. For more information, see Creating versions and setting permissions.

11. In the Extraction box, choose the method you want to use.
    • Scale Band—Uses a scale range, specified in the ScaleBands.xml, to determine which features will be included in the replica. Click the Scale Band drop-down arrow to define the scale.
    • Custom—An SQL statement that allows you to determine which features are included in the replica. You can modify the provided statement of 0 to 1,000,000 scale or click SQL to build your own query.

      Astuce :

      Use only the fields listed in the SQL Builder dialog box. For more information, see Building a query expression.

12. Click the ellipsis button (…) next to Replicate To.
13. Browse to and choose the template geodatabase.

    The target file geodatabase should not contain features.

14. Click Add.

    Astuce :

    If you would like to change the child replica name when it is replicated, you can do so under the Replica Name text box. Replica names must be unique and not contain special characters.

15. Click OK.

    The Creating Checkout Replica progress dialog box appears.

16. Click OK when the process completes.

You can now synchronize your changes back to the NIS database.
