Managing airport signs and annotation

获得 Aviation Airports 许可后可用。

The Manage Airport Signs tool allows you to create or edit airport sign data and annotation. The tool meets the FAA's 18C specification (AC 150/5300-18C) for airport sign data storage through an easy-to-use interface. This interface shows a preview and provides integration with annotation creation and updates.

The functionality to view these signs in 3D is included with ArcGIS Aviation. In the 3D Support folder in the install directory, there is a rule package that will allow you to render these signs in 3D using the procedural symbology inside ArcGIS Pro.

Requirements for managing airport signs

To work with the Manage Airport Signs tool on the Aviation Airports toolbar, the following two feature classes must exist in the Airports database:

• AirportSign feature class—An existing point feature class within the Airports database.
• AirportSign_A feature class—This feature class must be created within the Airports database with a projected coordinate system applied.

Creating an annotation feature class for storing airport sign annotations

1. Create a new annotation feature class with the name AirportSign_A.

   For more information, see Creating a feature-linked annotation feature class in a feature dataset and About creating annotation feature classes.

2. Link to the AirportSign feature class.
3. Set a Reference Scale of 1:1000.
4. Ensure the new annotation feature class is using the Maplex Label Engine.

   注：

   Once the annotation class is created, set the rest of the parameters in the annotation class properties.

5. Create two annotation classes, and label them Front and Back.
6. Change the label field for each annotation class.
   1. For the back annotation class: AirportSignMsgBack
   2. For the front annotation class: AirportSignMsgFront
7. Set the default font to SimHei, size 8.

   注：

   At Windows 10, the SimHei font is no longer installed by default.

   For setting up the default font to Sim Hei, browse to Control Panel > Appearence and Personalization > Fonts and select Download fonts for all languages.

8. To enable the use of leader lines between the sign annotation and associated Airport Sign point, click Leader and choose from the options.
9. Uncheck the Accent check box and reduce Gap to 0.00.

   注：

   If you have created sign annotation without leaders configured before the 10.4.1 or 11.0 release, all annotation features must be deleted and re-created to properly display the leader lines.

10. Set Placement Properties to determine initial annotation placement.
    1. Under Placement Properties, set the position to South for the Front annotation class, and North for the Back annotation class.
    2. Uncheck the Stack label check box.
    3. Enter a Label Offset value of 50 points.
    4. Click Properties > Label Position > Label Offset.
    5. Check the Measure Offset check box to measure from the exact symbol outline.

    注：

    Symbol text alignment is automatically set by the Manage Airport Signs tool, with Vertical Alignment set to Bottom and Horizontal Alignment set to Center. These will override any settings present in this annotation class.

11. Add an SQL query to each annotation class to ensure the AirportSignMsg fields are not null or don't contain an empty string.

    注：

    SQL uses two single quotation marks, with no space between them, to select an empty string.

    1. For the Back annotation class: AIRPORTSIGNMSGBACK IS NOT NULL AND AIRPORTSIGNMSGBACK <> ''
    2. For the Front annotation class: AIRPORTSIGNMSGFRONT IS NOT NULL AND AIRPORTSIGNMSGFRONT <> ''
12. Add the label expression to the Front and Back classes.
    1. Click Expression.
    2. Check the Advanced check box and paste the expression replacing the function already generated.

       注：

       In this function, ensure Front is using the AirportSignMsgFront field and Back is using the AirportSignMsgBack field.

13. Click Next on the next two dialog boxes.
14. Click Finish to create the annotation feature class.

    The annotation feature class to store the airport sign annotations is created in the geodatabase.

Custom tags

The Manage Airport Signs tool uses custom tags within the lxp to display airport signs as they would look in the real world. Using the tags to change the look of signs gives display flexibility that is unique to airports and their needs.

• sBackground = "<BGD: tags to control the background for the sign.
  • Red—Red RGB value for sign fill.
  • Blue—Blue RGB value for sign fill.
  • Green—Green RGB value for sign fill.
  • Left—Left margin spacing between the sign box and text.
  • Right—Right margin spacing between the sign box and text.
  • Halo—Point size of the halo surrounding the sign symbol (only applies to No Entry, Stop, and Yield sign types).
  • Width—By default the annotation sign box has a black outline. Setting this to -1 removes the outline completely. Setting this to 0 leaves an outline.
  • Valign—Controls the vertical alignment of the symbol within the sign box (only applies to Runway Critical, Runway Safety Area, and Taxiway End sign types).
  • Outline_red—Red RGB value for outline within the sign border (specifically applies to Location sign type).
  • Outline_green—Green RGB value for outline within the sign border (specifically applies to Location sign type).
  • Outline_blue—Blue RGB value for outline within the sign border (specifically applies to Location sign type).
  • Outline_width—Controls the thickness of the outline within the sign border (specifically applies to Location sign type).
  • Outline_margin—Controls the location of the outline within the sign border, whether closer to center of sign or closer to edges of the sign (specifically applies to Location sign type).

• sFont = sFontAirportSign: Overrides the default font for the annotation with the Esri Airport Sign font (only applies to No Entry, Runway Critical, Runway Safety Area, Taxiway End, Vehicle Stop, and Vehicle Yield sign types).

Managing settings

The Manage Airport Signs dialog box displays the Annotation Feature Class settings. These may be changed to point to the correct annotation feature class, and the correct attribute classes for the front and back of the signs. This only needs to be set once, so it may be minimized to allow room to configure other settings.

• Annotation Feature Class—The AirportSign_A feature class within the Airports database that will store the AirportSign annotation.
• Front Annotation Class—Used to display the Front message of the sign.
• Back Annotation Class—Used to display the Back message of the sign.

Managing AirportSign feature class attributes

The values in the fields are populated from the respective attribute fields in the AirportSign feature class. These values can be updated in the tool dialog box and saved in the geodatabase.

• Direction—AirportSignDirection field.
• Height Value—AirportSignHeightValue field.
• Purpose Code—AirportSignPurposeCode field.
• Type Code—AirportSignTypeCode field.

Managing sign previews (Front and Back)

The Front and Back previews provide a visual of how the sign will look in the annotation as well as the encoding that will be written into the database fields.

• Panels—A description of the AirportSignMsgBack and AirportSignMsgFront fields
• Sign Type—A list containing approved types of signs
• Text—The text messaging shown on the sign
• Add Arrow—Allows for arrow text to be entered

  注：

  It may be helpful to be familiar with the FAA's 18C specifications for AirportSign features to fully understand the types of signs to be created and the encoded values written to the AirportSignMsgFront and AirportSignMsgBack attributes. Adding more than one entry to each panel allows you to create complex signs containing more than one type of sign and associated messaging.

警告：

It is always recommended that you have a backup of your data whenever you make changes to your geodatabase.

1. Open the UpdateGeodatabaseSchema.exe file located at <Installation location>\AviationCharting\Desktop<version>\Utilities\UpdateGeodatabaseSchema.
2. Click the browse button (...) next to Input Schema.
3. Choose AirportSign.xml.
4. Click the browse button (...) to browse to the location of the log file that will summarize the differences.
5. Click Compare to see the changes that need to be applied.
