Updating an instance

Edits made on the central database repository (CDR or NIS) are packaged in an update file through the update instance process. Once you have created the update file, you can apply those changes to your product using the Apply Changes tool. Using this workflow, it is possible to create various ENs and ERs based on user requirements.

  1. Start ArcMap.
  2. On the main menu, click Customize > Toolbars > Production Editing.
  3. Add the NIS feature dataset.
  4. Create an edit version.
  5. Switch to the edit version you just created.
  6. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.

    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.


    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 Show/Hide Attributes on the Manage Features window.

  7. Make necessary edits to your NIS edit version in the cell/chart panel you are focused on.

    You can use the AOIs in your instance to locate your cell/chart among all the cells/charts in the NIS.

  8. Be sure you or your quality control administrator verifies the changes.

    Perform the substeps if you are the one who needs to verify the changes.

    1. Click the Update tab in the Manage Features window.
    2. Accept the necessary changes by changing the NIS_VERIFIED field to True.
  9. On the main menu, click Customize > Toolbars > Nautical.
  10. Click the Reconcile button Reconcile on the Nautical toolbar.
  11. Make sure the target version is the CDR or NIS database.
  12. Choose the By attribute (by column) option.
  13. Choose the In favor of the Target Version option.
  14. Click OK.
  15. Click the Nautical Post button Nautical Post on the Nautical toolbar.
  16. Click the Stop Editing button Stop Editing on the Production Editing toolbar.

    The geodatabase becomes uneditable. If you have made edits, you will be prompted to save the changes if you want.

  17. NoteNote:

    An enhancement has been added to the Nautical Post tool. You cannot post data until all your features are marked as verified in the NIS_VERIFIED field.


    For NIS database maintenance, it is recommended that you delete your edit version and create another one once you have posted your changes to the DEFAULT version. This allows the database administrator to fully compress and analyze the database and increase overall performance.

  18. Navigate to the instance you want to update in the Product Library window.
  19. Right-click the instance in the product library tree and click Update Instance.

    The update XML files that will be applied to your product database are generated. These are stored in the product library and are automatically referenced when you start editing in your continual maintenance version.
