Generate Aviation Chart Leads (Aviation)

获得 Aviation Charting 许可后可用。

摘要

Creates text graphics at intersection points between a map frame boundary and line features.

Chart leads are text elements that are placed where a line feature intersects the edge of the map frame of an aeronautical chart (usually an Enroute chart). Chart leads indicate the next significant point for line features continuing past the map frame by displaying the name of the next designated point or Navigational aid (Navaid) along a particular route. The text to be displayed is based on the line features attributes. To symbolize and place the chart leads, the tool uses preferences. The preferences are configured using a specific interface and should be established before running the tool.

GenerateAviationChartLeads example (stand-alone script)

The following script demonstrates how to use the GenerateAviationChartLeads function.

import arcpy

# Check out Aeronautical extension

arcpy.CheckOutExtension("Aeronautical")

# Create a reference to the project file (.aprx) containing your layout

aprx = arcpy.mp.ArcGISProject(r"c:\data\ICAO.aprx")
in_layout = aprx.listLayouts("ICAO_ENR")[0]

# parameters
in_mapframe = "Layers Map Frame"
in_preferences_table = r'c:\data\AIS.gdb\Preferences'
preference = 'Enroute_Low'


# Run GenerateChartLeads

arcpy.aviation.GenerateAviationChartLeads(in_layout, in_mapframe, in_preferences_table, preference)

# Check in Aeronautical extension

arcpy.CheckInExtension("Aeronautical")
