Generate Airspace Areas (Aviation)

Available with Aviation Charting license.

Summary

Generates AirspaceArea features from Airspace features.

Overlapping three-dimensional Airspace features at various altitudes can be converted to two-dimensional AirspaceArea features. These converted features can be used as annotation to display the two-dimensional extent of an airspace on an aeronautical chart.

Usage

• The Input Airspace Features parameter value must be from the Airspace feature class from the AIS geodatabase schema.

  Learn more about the Airspace feature class

• The Target Airspace Area Features parameter value must be from the AirspaceArea feature class from the AIS geodatabase schema.

  Note:

  You can use this tool to update, delete, and create features for this feature class.

• The Vertical Limit Override Table parameter value must be the VerticalLimitOverride table from the AIS geodatabase schema.

• The Area of Interest Features polygon feature class is used to set a boundary within which airspace polygon features will be processed. Airspace polygon features that wholly or partially overlap the area of interest (AOI) will be processed.

  Note:

  The tool will only honor Area of Interest Features parameter values that are currently selected on a feature layer. If no AOI is selected, the tool will run using all features in the Area of Interest Features parameter.

• You can use a definition query on your AOI features to limit the number of features that are processed.

• You must populate the Preference Table value before running this tool. These preferences will define how the tool generates airspace lines. After a preference is created, you can update the attributes as necessary. You can also create multiple preferences by assigning a unique name to each preference in the table.

  This tool uses preferences to define the following properties:

  • Airspace Type— Limits processing to specific airspace types
  • Attribute filter (optional)—Uses an expression to control which airspace features are processed
  • Spatial selection—Limits processing to features that overlap and exist between specified high and low flight levels

  Note:

  When creating a preferences, you must have an AIS_AOI feature class in your map's table of contents.

Caution:

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

Code sample

GenerateAirspaceAreas example (stand-alone script)

The following script demonstrates how to use the GenerateAirspaceAreas function.

# Name: GenerateAirspaceAreas_example.py
# Description: Generates AirspaceArea features from 
# input Airspace features.

import arcpy

# Check out extension
arcpy.CheckOutExtension("Aeronautical")

# Setup a workspace reference
arcpy.env.workspace = r"D:\Data.gdb"

# Parameters
in_airspace_features = "Airspace"
target_airspace_area_features = "AirspaceArea"
aoi_features = "AOI"
preference_table = "Preferences"
preference = "MyPreference"
derived_airspace_part_features = "AirspaceParts"

# Run the GenerateAirspaceAreas function
arcpy.aviation.GenerateAirspaceAreas(in_airspace_features, target_airspace_area_features, aoi_features, preference_table, preference, derived_airspace_part_features)

# Check in extension
arcpy.CheckInExtension("Aeronautical")
