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})

Parameter	Explanation	Data 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_1 —Coordinates will be formatted in a decimal degrees coordinate pair stored in a single field with coordinates separated by a space, comma, or slash. DD_2 —Coordinates will be formatted in a decimal degrees coordinate pair stored in two table fields. This is the default. DDM_1 —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. DDM_2 —Coordinates will be formatted in a degrees and decimal minutes coordinate pair stored in two table fields. DMS_1 —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. DMS_2 —Coordinates will be formatted in a degrees, minutes, and seconds coordinate pair stored in two table fields. GARS —Coordinates will be formatted in Global Area Reference System. GEOREF — Coordinates will be formatted in World Geographic Reference System. UTM_BANDS —Coordinates will be formatted in Universal Transverse Mercator coordinate bands. UTM_ZONES —Coordinates will be formatted in Universal Transverse Mercator coordinate zones. USNG —Coordinates will be formatted in United States National Grid. MGRS —Coordinates 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.	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)
