Create kml from csv in Python

Question

I am new to Python. I am working on gps files. I need to convert a CSV file having all the gps data to kml file. Below is the code in python I am using :

import csv
#Input the file name.
fname = raw_input("Enter file name WITHOUT extension: ")
data = csv.reader(open(fname + '.csv'), delimiter = ',')
#Skip the 1st header row.
data.next()
#Open the file to be written.
f = open('csv2kml.kml', 'w')

#Writing the kml file.
f.write("<?xml version='1.0' encoding='UTF-8'?>\n")
f.write("<kml xmlns='http://earth.google.com/kml/2.1'>\n")
f.write("<Document>\n")
f.write("   <name>" + fname + '.kml' +"</name>\n")
for row in data:
    f.write("   <Placemark>\n")
    f.write("       <name>" + str(row[1]) + "</name>\n")
    f.write("       <description>" + str(row[0]) + "</description>\n")
    f.write("       <Point>\n")
    f.write("           <coordinates>" + str(row[3]) + "," + str(row[2]) + "," + str(row[4]) + "</coordinates>\n")
    f.write("       </Point>\n")
    f.write("   </Placemark>\n")
f.write("</Document>\n")
f.write("</kml>\n")
print "File Created. "
print "Press ENTER to exit. "
raw_input()

The csv file I am using is available here : dip12Sep11newEdited.csv The kml file generated is available here : csv2kml.kml But the kml file is not getting created correctly. Apparently after some rows in the csv the code is not able to generate more Placemarks. Its not able to iterate. You can see that by scrolling to the last part of the kml file generated.

Can anyone help me finding out the error in the code, because for some smaller csv files it worked correctly and created kml files fully.

Thanks.

Answer 1

This code is well written thank you for the post. I got it to work by putting my CSV in the same directory as the .py code.

I made a few edits to bring it to py 3.3

import csv
#Input the file name."JoeDupes3_forearth"
fname = input("Enter file name WITHOUT extension: ")
data = csv.reader(open(fname + '.csv'), delimiter = ',')
#Skip the 1st header row.
#data.next()
#Open the file to be written.
f = open('csv2kml.kml', 'w')

#Writing the kml file.
f.write("<?xml version='1.0' encoding='UTF-8'?>\n")
f.write("<kml xmlns='http://earth.google.com/kml/2.1'>\n")
f.write("<Document>\n")
f.write("   <name>" + fname + '.kml' +"</name>\n")
for row in data:
    f.write("   <Placemark>\n")
    f.write("       <name>" + str(row[1]) + "</name>\n")
    f.write("       <description>" + str(row[3]) + "</description>\n")
    f.write("       <Point>\n")
    f.write("           <coordinates>" + str(row[10]) + "," + str(row[11]) + "," + str() + "</coordinates>\n")
    f.write("       </Point>\n")
    f.write("   </Placemark>\n")
f.write("</Document>\n")
f.write("</kml>\n")
print ("File Created. ")
print ("Press ENTER to exit. ")
input()
f.close()

Hope it helps if you are trying to convert your data.

You didn't answer the query above, but my guess is that the error is that you're not closing your output file (which would flush your output).

f.close()
