Workflow: Creating annotation with an advanced callout and multiple text elements

The advanced callout functionality allows you to modify the background symbol, shape, margins, splits, and leader line of the callout. The multiple text element functionality allows you to have multiple and individual text elements, including a vertical Morse code element, whose placement and style can be edited. Several steps are involved in creating advanced callout annotation with multiple text elements: setting up cartographic feature classes, creating annotation feature classes, setting up calculated field specifications, and creating and editing advanced annotation.

Setting up cartographic feature classes

The cartographic feature class is where the initial text string is calculated to create annotation. This is typically done in a field such as Label_Txt. The text string produced by the XML script contains all the formatting and identification tags and is lengthy, meaning the field must be set to a high value to avoid any database conflicts.

Since the annotation is generated based on the text string field, it requires that the length of the field containing the label be long enough to accommodate the labels generated by the XML scripts.

1. 启动 ArcCatalog。
2. Navigate to the geodatabase that contains the cartographic feature class you want to use for generating annotation.
3. Right-click the cartographic feature class and click Properties.

   Learn more about cartographic features

   The Feature Class Properties dialog box appears.

   

4. In the Field Name column, select Label_Txt or a similar field.
5. Verify that the Length property under Field Properties is set to a value greater than 2,000.
6. If the value is less than 2,000, add a field by clicking in the blank row in the Field Name column and type a name.
7. Click in the Data Type column next to the new field's name and choose Text.
8. To create an alias for this field, click the field next to Alias and type the alias for this field.
9. To allow null values to be stored in this field, click the field next to Allow NULL values, click the drop-down arrow, then click Yes.
10. Set the Length property to 2000.
11. 单击完成。

提示:

If the cartographic feature class is already created, you can set the field length when creating or editing a calculated field rule or in SQL Server Management Studio if you are using a SQL-based database.

Creating an annotation feature class

An annotation feature class that uses the advanced callout/multiple text element functionality is not much different than any other annotation feature class within the database. However, annotation feature classes that have the advanced callout/multiple text element functionality need to be created with a few additional parameters that need to be set to ensure that the annotation is created correctly.

For additional information, see Creating aviation annotation feature classes.

In addition to creating feature-linked annotation, annotation feature classes with advanced callouts require defining properties for the background, shadow, arrowhead, margin, callout, and placement options.

Setting up the calculated field specification

You must have previously set up visual specifications and specified the location of the visual specifications table in the database you are using. Visual specifications are used to calculate the individual values for each record in the database according to the XML script. The XML script must be configured for each individual annotation feature class to be able to create annotation.

Calculated fields allow you to determine the appearance of labels and annotation or basic data type values based on attributes you select. The fields are grouped based on the specification you choose.

1. 启动 ArcMap。
2. Click the Visual Specifications button on the Production Symbology toolbar.

   The Visual Specifications dialog box appears.

   

3. Make sure that you check the Display Calculated Representation and Calculated Fields tabs check box.
4. 单击确定。
5. Right-click the cartographic feature class for which you want to define the calculated fields and click Properties.

   The Layer Properties dialog box appears.

6. Click the Calculated Fields tab.
7. Click the Specification drop-down arrow and choose the specification for which you want to create the field rule.
8. Add a new calculated field rule by right-clicking anywhere in the white space where the rules are displayed and clicking New Rule.

   

   A new row appears in the rule table.

   提示:

   You can also click Options > New Rule.

9. Double-click the Rule Description space for the new rule and type a description.
10. Click the ellipsis (...) in the Field Name cell.

    The Field Properties dialog box appears.

11. Choose the appropriate field from the Name drop-down list and ensure that its length is at least 2000.

    

    注:

    If the length is less than 2,000, you can add a field with length greater than 2000 in ArcCatalog.

12. 单击确定。
13. Click the SQL Statement drop-down arrow and choose Edit SQL Statement.
14. Type the SQL statement for the features you want to include with the rule.

    

    For additional information about defining a SQL statement, see Defining SQL statements for visual specifications.

15. 单击确定。
16. Click the Expression drop-down arrow and choose Edit Expression.

    The Expression Parser dialog box appears.

17. Type, or copy and paste, the custom XML script into the Expression text box.

    

    提示:

    You can import an XML in VB Script File if you have one already by clicking Load.

    注:

    You can also use the Advanced Callout Script Builder tool to generate the LXP.

23. 单击确定。

Creating advanced annotation

To generate annotation using the Create Feature-Linked Annotation tool, you must have the annotation feature class, as well as the linked source feature class, loaded into the Table Of Contents window. The data frame also needs to be associated with an instance from the product library for which annotation has to be created.

1. Ensure that the correct product library and production database are set.
2. Make sure that the Instances Maintained property is set correctly from the Configure context menu on the Product Library window.
3. Verify that each annotation feature layer you are creating annotation for has its own matching source feature layer in the document.
4. On the main menu, click View > Data Frame Properties.
   1. Click the General tab.
   2. Verify that the data frame's reference scale matches that of the given chart.
   3. Verify that the data frame's rotation matches that of the given chart.
   4. Verify that the Label Engine is set to Maplex Label Engine.
   5. Click the Coordinate System tab.
   6. Verify that the data frame's projection matches that of the given chart.
   7. Click OK.
5. On the main menu, click Customize > Toolbars > Aviation Data Management.
6. Click the Feature Display Settings button on the Aviation Data Management toolbar.
   1. Make sure the correct definition queries are being used for each layer you want annotated.
   2. Click OK.
7. On the main menu, click Customize > Toolbars > Aviation Annotation.
8. Click the Create Feature-Linked Annotation button on the Aviation Annotation toolbar.

   The Create Feature-Linked Annotation dialog box appears.

   

9. Check the check boxes next to the instances you want to process.

   The list displayed is built from the Instances Maintained set through the Product Library window.

10. Check the check boxes next to the annotation classes in the Annotation Class(es) to Process list.

    提示:

    You can use the Select All, Clear All, and individual check boxes to choose the annotation classes.

11. Click OK.

    For each feature class that is linked to the annotation feature classes, the tool determines which features do not have annotation in the selected chart. It then creates annotation for those features. It also gives the annotation a MAPID, ensures word spacing is set to 100, changes the color of the background symbol, and resizes arrowheads and accent bar gaps so they are correct for the map scale.

    The Create Feature-Linked Annotation Results dialog box appears and shows the results of the annotation that has been generated, updated, or deleted.

12. Click Close once you are finished viewing the results.
13. 单击关闭。

Editing advanced annotation

Editing advanced annotation has all the customization ability that the XML provides but allows you to customize individual pieces of annotation and override the settings in the XML.

Advanced callout annotation can be edited and customized in an edit session by editing parameters on the Editor dialog box. You can set a variety of parameters and placement options for the appearance of an advanced callout annotation.

1. On the main menu, click Customize > Toolbars > Aviation Editing.
2. Click the Production Start Editing button on the Aviation 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.

注:

If using a versioned environment, make sure you are in the correct database.

3. Click the Edit Annotation tool on the Aviation Annotation toolbar.
4. Click an advanced annotation feature to select it.
5. Right-click the annotation piece and click Properties.

   提示:

   You can also click the Attributes button on the Editor toolbar.

6. Click Leader.
7. Check the Use Custom check box.

   

   注:

   The Use Custom check box is very important. The attributes you set in the menu will not be applied to that piece of annotation unless this check box is checked.

8. Modify the Background, Shadow, Callout, Arrowhead, and Margins parameters in the Editor dialog box to customize the annotation as necessary.

   提示:

   You can view a list of the advanced callout/multiple text element annotation parameters.

9. Click Placement Options.

   The Text Placement Properties dialog box appears.

   

10. Check the Use Custom check box.
11. Modify the placement properties of the Top, Middle, Bottom, Left, and Right text elements as necessary.

    注:

    Only options that are available are active.

12. Click OK.

    The Editor dialog box appears.

13. Click OK on the Editor dialog box.

    The Attributes dialog box appears.

14. Click Apply on the Attributes dialog box.
15. Click OK to close the Attributes dialog box.

Creating a label expression (LXP)

A label expression is used to adjust the formatting of your annotation. This uses ArcGIS formatting tags to control how the annotation displays the font, size, color, orientation, or line weight. If you intend to use annotation abbreviation options, see the example LXP below.

注:

You can also use the Advanced Callout Script Builder tool to generate the LXP.

The label expression below can be used to abbreviate advanced/callout annotation.
