Group Route Segments (Aviation)

获得 Aviation Charting 许可后可用。

摘要

Derives additional cumulative information, such as the total distance of a route or route portion from individual segments, to prepare data for charting.

This tool identifies routes and route portions in FAA and NGA ATSRoute data.

A route collection is an ordered set of ATSRoute segments from a NAVAID to a NAVAID. For each route collection identified, an entry will be stored in the EnrouteInformation stand-alone table with the total calculated distance of each group.

A route portion collection is a subset of an en route collection containing segments from a compulsory point to a compulsory point. A route portion can also go from a NAVAID or compulsory point to a NAVAID or compulsory point. For each route portion collection identified, an entry will be stored in the RoutePortion stand-alone table.

使用情况

• The tool requires the following feature classes, tables, and attributes:

  Name	Required fields
  ATSRoute—Feature class	IDENT_TXT EnrouteInformation_Id StartPoint_Id EndPoint_Id RepATCStart_Code RepATCEnd_Code
  EnrouteInformation—Stand-alone table	GFID Distance_Val
  RoutePortion—Stand-alone table	GFID EnrouteInformation_Id Distance_Val StartPoint_Id EndPoint_Id
  DesigPoint_NavaidAssoc—Attributed relationship class	DesignatedPoint_ID NavaidRole_Code

  The DesigPoint_NavaidAssoc relationship class is required to determine the collocation of a designated point with a NAVAID. A NavaidRole_Code attribute value of 2 indicates that a given DesignedPoint is collocated with a NAVAID.

  If required attributes are missing, an error occurs listing the dataset name and missing attributes.

  注：

  The ArcGIS Aviation Charting product files contain additional information about the AIS schemas that are available for download.

标注	说明	数据类型
Target ATS Route Features	The input feature class for the ATSRoute feature class that contains polylines. The Enrouteinformation_Id and the RoutePortion_Id attributes will be updated.	Feature Layer
Target Enrouteinformation Table	The table that will be updated to contain entries for the en route segments identified during processing. The Distance_Val attribute is set to the total length of the en route segments. The Distance_Val attribute is updated and kept up to date on new and existing en route segments.	Table View
Target RoutePortion Table	The table that will be updated to contain entries for the route portions identified during processing. The Distance_Val attribute is set to the total length of the route portions' segments. The route portions' StartPoint_Id and EndPoint_Id attributes will also be updated to refer to the start and end point of a route portion.	Table View
Designated Point Navaid Association Table	The association table, DesigPoint_NavaidAssoc, that contains the relationships between designated points and NAVAID systems. The ATSRoute feature class's start and end designated point's GFID field will reference entries in this table. This table indicates whether a point is collocated with a NAVAID and helps determine the grouping of route segments.	Table View

代码示例

GroupRouteSegments example (stand-alone script)

The following script demonstrates how to use the GroupRouteSegments function.

# Import system modules
import arcpy

# Check out extensions
arcpy.CheckOutExtension('Aeronautical')

# Set local variables
target_atsroute_features = r"C:\data\aeronautical.gdb\ATSRoutes"
target_enroute_table = r"C:\data\aeronautical.gdb\EnrouteInformation"
target_routeportion_table = r"C:\data\aeronautical.gdb\RoutePortion"
in_association_table = r"C:\data\aeronautical.gdb\DesigPoint_NavaidAssoc"

# Call the GroupRouteSegments tool
arcpy.aviation.GroupRouteSegments(target_atsroute_features, target_enroute_table,\
                                  target_routeportion_table, in_association_table)

# Check in extensions
arcpy.CheckInExtension('Aeronautical')
