Write polyline vertices to csv

Question

I am looking for some code to write out each line feature in a feature class/shapefile to a csv file that would look something like this:

FID, X, Y

All help is appreciated.

thanks

Tony

I am not sure, but will the 'Export Feature Attribute to ASCII' tool do the trick?

I found it under Spatial Statistics -> Utilities ....

A search cursor like this could easily iterate through all the points and add them to a csv file for you.

The key here is to use the "explode to points" method in the search cursor
import csv
        
with arcpy.da.SearchCursor(featureClass, ["OID@","SHAPE@XY"],explode_to_points=True) as cursor:
    with open("outputFile.csv","wb") as csvfile:
        writer = csv.writer(csvfile)
        writer.writerow(["FID","LAT","LON"])
        for row in cursor:
            FID = row[0]
            lat = row[1][1]
            lon = row[1][0]
            writer.writerow([FID,lat,lon])

Hope this helps!

You could also use the python csv module to write the file out.
