Managing airport signs and annotation

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 also included with the ArcGIS for Aviation solution. 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 either the geoprocessing tools available in ArcScene or the procedural symbology inside ArcGIS Pro. See the documentation regarding using a rule package in the respective technology for more information.

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 annotation feature class for storing airport sign annotations

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

   Remarque :

   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:
   1. For the back annotation class: AirportSignMsgBack
   2. For the front annotation class: AirportSignMsgFront
7. Set the default font to SimHei, size 8.
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 Accent bar and reduce Gap to 0.00

   Remarque :

   If you have created sign annotation without leaders configured before the 10.4.1 release, all annotation features must be deleted and recreated 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. Un-check Stack label.
    3. Enter a Label Offset value of 50 points.
    4. Click Properties > Label Position > Label Offset
    5. Check the box to Measure Offset from the exact symbol outline.

    Remarque :

    Symbol text alignment is automatically set by the Manage Airport Signs tool with Vertical Alignment to Bottom and Horizontal Alignment 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.

    Remarque :

    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. Open Expression.
    2. Check the Advanced checkbox and paste the expression replacing the function already generated.

       Remarque :

       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 - blur rgb value for sign fill
  • green - green rgb value for sign fill
  • left - left margin spacing between sign box and text
  • right - right margin spacing between 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 outline completely. Setting this to 0 leaves an outline.
  • Valign - controls 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 thickness of the outline within the sign border (specifically applies to Location sign type)
  • outline_margin - controls location of 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 Aiport Sign font (only applies to No Entry, Runway Critical, Runway Safety Area, Taxiway End, Vehicle Stop, and Vehicle Yield sign types).

Managing settings

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—Drop-down list containing approved types of signs.
• Text—The text messaging shown on the sign.
• Add Arrow—Allows for arrow text to be entered.

  Remarque :

  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.
