I have a feature class with thousands of points. In the same table with these point locations, I have two additional fields. One for azimuth, and one for a length (or distance) to move along that azimuth in order to create a new point location. I am looking for guidance on a python script that would accomplish this task?

table example 
x             y          length_fornew_point       azimuth 
400460.99 135836.76       5150.04                    55.41 
.... ....

Ultimately the script would run through my table, look at the existing coordinates and create a new end point at corresponding specified distance/azimuth in the table.

These two coordinates would then be used to create a new two point polyline.

  • Do you have access to the arcpy site-package?

  • Hmmmm. How would I determine that? I'm using ArcGis 10.2 if that helps. Sorry.

ArcGIS has a tool to do just that called Bearing Distance To Line (Data Management).

enter image description here

The syntax is as follows (from ESRI help):

# Import system modules
import arcpy
from arcpy import env

# Local variables
input_table = r"c:\workspace\LOBtraffic.dbf"
output_fc = r"c:\workspace\SOPA.gdb\lob_traf001"

arcpy.BearingDistanceToLine_management(input_table, output_fc, "X", "Y", 
"NAUTICAL_MILES", "azim", "DEGREES", "GEODESIC","recnum")
