Adding annotation (Maritime Charting)

The Digital Nautical Chart (DNC) data model stores text features in the Ecrtext annotation feature class at all scales. Annotation features display as text in the map display area. The size and shape of annotation features should match their respective hard-copy source text features.

You can either import annotation into the geodatabase or create it in an edit session. You must generate a Dqyarea feature before collecting Ecrtext features. The Dqyarea feature is required to calculate the correct size of the annotation. Therefore, you can collect annotation anytime during the production process as long as Dqyarea exists.

A geodatabase annotation feature class requires that a reference scale be set, which is applied to all text collected in that feature class. However, a DNC library can be composed of multiple charts of varying scales. The Add DNC Annotation tool allows flexibility by calculating the true size of an annotation feature based on the scale of the Dqyarea (chart) feature class in which it resides.

Pasos:

1. Start ArcMap.
2. If necessary, set up the DNC production environment.
3. Click the Production Start Editing button on the Production Editing toolbar.
   Nota:

   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.

   Sugerencia:

   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.

4. Verify that the Ecrtext feature class is in the Table of Contents window.
5. Click the Add DNC Annotation button on the Nautical DNC toolbar.

   The Add DNC Annotation dialog box appears.

6. In the Display Map Scale Properties area, click the Browse button next to Map index layer.

   The Select Map Index Layer dialog box appears.

7. Navigate to the Dqyarea feature class from the geodatabase currently being edited and click OK.
8. Click the Scale Field drop-down arrow and choose a field.
9. Click the Target Layer drop-down arrow and choose Ecrtext.
10. Click the Font Size drop-down arrow and choose a size.
11. Type your annotation text into the text box.
12. Choose the appropriate Geometry Type:
    • Point—Creates a single point horizontal text
    • Line—Creates diagonal or splined text
13. Haga clic en Agregar.
14. Depending on the Geometry Type you set in step 12, do one of the following to add a feature:

    To add a point	Click in the middle of the placement location in the map display.
    To add a line	Digitize a sketch line over the placement location in the map display. Double-click to finish the sketch.

    Sugerencia:

    Click the Edit Annotation button on the Add DNC Annotation dialog box to select and modify annotation features. The tool is disabled if there is not at least one geodatabase annotation layer set as selectable in an edit session.
