Coordinate Table To Polyline (Defense)

Summary

Creates a polyline feature class from coordinates stored in a table.

Usage

  • Fields from the input table will not be copied to the output polyline feature class.

Syntax

CoordinateTableToPolyline(in_table, out_feature_class, x_or_lon_field, in_coordinate_format, {y_or_lat_field}, {line_group_field}, {sort_field}, {coordinate_system})
ParameterExplanationData Type
in_table

The table containing the source coordinates.

Table View
out_feature_class

The feature class containing the output polyline features.

Feature Class
x_or_lon_field

The field in the input table containing the x or longitude coordinates.

Field
in_coordinate_format

Specifies the format of the input table coordinates.

  • DD_1Coordinates will be formatted in a decimal degrees coordinate pair stored in a single field with coordinates separated by a space, comma, or slash.
  • DD_2Coordinates will be formatted in a decimal degrees coordinate pair stored in two table fields. This is the default.
  • DDM_1Coordinates will be formatted in a degrees and decimal minutes coordinate pair stored in a single table field with coordinates separated by a space, comma, or slash.
  • DDM_2Coordinates will be formatted in a degrees and decimal minutes coordinate pair stored in two table fields.
  • DMS_1Coordinates will be formatted in a degrees, minutes, and seconds coordinate pair stored in a single table field with coordinates separated by a space, comma, or slash.
  • DMS_2Coordinates will be formatted in a degrees, minutes, and seconds coordinate pair stored in two table fields.
  • GARSCoordinates will be formatted in Global Area Reference System.
  • GEOREF Coordinates will be formatted in World Geographic Reference System.
  • UTM_BANDSCoordinates will be formatted in Universal Transverse Mercator coordinate bands.
  • UTM_ZONESCoordinates will be formatted in Universal Transverse Mercator coordinate zones.
  • USNGCoordinates will be formatted in United States National Grid.
  • MGRSCoordinates will be formatted in Military Grid Reference System.
String
y_or_lat_field
(Optional)

The field in the input table containing the y or latitude coordinates.

The y_or_lat_field parameter is used when the in_coordinate_format parameter is set to DD_2, DDM_2, or DMS_2.

Field
line_group_field
(Optional)

The field in the input table field used to create unique polylines. A polyline will be created for each unique value.

Field
sort_field
(Optional)

The field in the input table used to order the polyline vertices. The field must be numeric.

Field
coordinate_system
(Optional)

The spatial reference of the output feature class. The default is GCS_WGS_1984.

Code sample

CoordinateTableToPolyline example 1 (Python window)

The following Python window script demonstrates how to use the CoordinateTableToPolyline function.

import arcpy
arcpy.env.workspace = r"C:/Data.gdb"
arcpy.CoordinateTableToPolyline_defense(r"C:/CSV/TableToPolyline.csv", 
                                        "Out_Polyline", "POINT_X", "DD_2", 
                                        "POINT_Y", "Group_")
CoordinateTableToPolyline example 2 (stand-alone script)

The following Python example shows how to use the CoordinateTableToPolyline function in a sample workflow.

# Description: Create polylines from tabular data and find a representative 
#              center point of each line.

# Import system modules
import arcpy

# Set environment settings
arcpy.env.workspace = r"C:/Data.gdb"
arcpy.env.overwriteOutput = True

# Create polylines
input_table = r"C:/CSV/TableToPolyline.csv"
result_line = "Output_Polyline"
arcpy.CoordinateTableToPolyline_defense(input_table, result_line, "POINT_X", 
                                        "DD_2", "POINT_Y", "Group_")

# Find representative center point
result_center = "Output_Centers"
arcpy.FeatureToPoint_management(result_line, result_center)
