Parameters

Dialog

Label	Explanation	Data Type
Input Table	The table containing the source coordinates.	Table View
Output Polyline Feature Class	The feature class containing the output polyline features.	Feature Class
X Field (Longitude, UTM, MGRS, USNG, GARS, GeoRef)	The field in the input table containing the x or longitude coordinates.	Field
Input Coordinate Format	Specifies the format of the input table coordinates. Decimal Degrees - One Field—Coordinates will be formatted in a decimal degrees coordinate pair stored in a single field with coordinates separated by a space, comma, or slash. Decimal Degrees - Two Fields—Coordinates will be formatted in a decimal degrees coordinate pair stored in two table fields. This is the default. Degrees and Decimal Minutes - One Field—Coordinates 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. Degrees and Decimal Minutes - Two Fields—Coordinates will be formatted in a degrees and decimal minutes coordinate pair stored in two table fields. Degrees, Minutes, and Seconds - One Field—Coordinates 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. Degrees, Minutes, and Seconds - Two Fields—Coordinates will be formatted in a degrees, minutes, and seconds coordinate pair stored in two table fields. Global Area Reference System—Coordinates will be formatted in Global Area Reference System. World Geographic Reference System— Coordinates will be formatted in World Geographic Reference System. Universal Transverse Mercator Bands—Coordinates will be formatted in Universal Transverse Mercator coordinate bands. Universal Transverse Mercator Zones—Coordinates will be formatted in Universal Transverse Mercator coordinate zones. United States National Grid—Coordinates will be formatted in United States National Grid. Military Grid Reference System—Coordinates will be formatted in Military Grid Reference System.	String
Y Field (Latitude) (Optional)	The field in the input table containing the y or latitude coordinates. The Y Field (latitude) parameter is used when the Input Coordinate Format parameter is set to Decimal Degrees - Two Fields, Degrees and Decimal Minutes - Two Fields, or Degrees Minutes and Seconds - Two Fields.	Field
Line Grouping 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
Output Coordinate System (Optional)	The spatial reference of the output feature class. The default is GCS_WGS_1984.	Spatial Reference

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)
