Calculate ATS Route Attributes (Aviation)

Доступно с лицензией Aviation Charting.

Краткая информация

Calculates segment distance and bearing attributes on Air Traffic Service (ATS) route features.

This tool calculates the magnetic track and reverse magnetic track based on the magnetic variation at the endpoints of routes.

Использование

• The Input ATS Route Feature Layer parameter value must be a polyline.

• If the ATS Route Attributes parameter is set to Magnetic Track or Reverse Magnetic Track, the Magnetic Variation Date parameter must be specified.

• The attributes calculated are written to existing fields in the Input ATS Route Feature Layer parameter value. If those fields do not exist, you must add them before running the tool. The specific fields are the following:

  • Length—The route distance from the start to the end
  • Magnetic Track—The adjusted value for magnetic variation from the start to the end of a route
  • Reverse Magnetic Track—The adjusted value for magnetic variation from the end to the start of a route
  • Reverse True Track—The bearing values of the route from the end position to the start of the route
  • True Track—The bearing values of the route from the start position to the end of the route

CalculateATSRouteAttributes example (stand-alone script)

The following script demonstrates how to use the CalculateATSRouteAttributes function.

import arcpy

# Check Out Aeronautical Extension
arcpy.CheckOutExtension("Aeronautical")

#Input ATS Route Feature Layer
in_features = r"C:\data\AIS.gdb\ATSRoutes"

#Add fields in the in_features if not exist already
arcpy.AddField_management(in_features, 'Length', 'DOUBLE')
arcpy.AddField_management(in_features, 'TRUETRACK_VAL', 'DOUBLE')
arcpy.AddField_management(in_features, 'REVERSETRUETRACK_VAL', 'DOUBLE')
arcpy.AddField_management(in_features, 'MAGTRACK_VAL', 'DOUBLE')
arcpy.AddField_management(in_features, 'REVERSE_MAG_TRACK', 'DOUBLE')

#Input ATS Route Attributes to be calculated
atsroute_attributes= "LENGTH Length;TRUE_TRACK TRUETRACK_VAL;REVERSE_TRUE_TRACK REVERSETRUETRACK_VAL;MAG_TRACK MAGTRACK_VAL;REVERSE_MAG_TRACK REVERSEMAGTRACK_VAL"

#Input Magnetic Variation Date
magnetic_variation="12/31/2021 10:52:18 AM"

# Exceute Calculate ATSRoute Attributes
arcpy.aviation.CalculateATSRouteAttributes(in_features, atsroute_attributes, magnetic_variation)

# Check In Aeronautical Extension
arcpy.CheckInExtension("Aeronautical")
