convert pandas DataFrame or list of longitude and latitudes to a gpx file in python

Question

I have longitude and latitude values in a pandas DataFrame but I want to convert it to a gpx file so I can visualize it later in google maps. how can I do that with python ? I took a look at the gpxpy library but the examples shows how to load or read a gpx file and I want to do the opposite. I want to read a csv file and turn it to gpx file or directly convert from pandas Dataframe.

Please refer to this: https://pypi.org/project/gpxpy/

I guess you will need the package for your task. And then you could use their provided example:

import gpxpy
import gpxpy.gpx

with open("outfile.gpx", "w") as f:
    f.write( gpx.to_xml())

Converting a pandas df to xml is described here:

What about this: (adapted from the create-file section of https://pypi.org/project/gpxpy/)

# import pandas as pd
# import numpy as np

# df = pd.DataFrame(90*np.random.random((5, 2)))

# print(df)

import gpxpy
import gpxpy.gpx

gpx = gpxpy.gpx.GPX()

# Create first track in our GPX:
gpx_track = gpxpy.gpx.GPXTrack()
gpx.tracks.append(gpx_track)

# Create first segment in our GPX track:
gpx_segment = gpxpy.gpx.GPXTrackSegment()
gpx_track.segments.append(gpx_segment)

# Create points:
for idx in df.index:
    gpx_segment.points.append(gpxpy.gpx.GPXTrackPoint(df.loc[idx, 0], df.loc[idx, 1]))

# print(gpx.to_xml())

with open('output.gpx', 'w') as f:
    f.write(gpx.to_xml())

example data of code above:

dataframe:

#            0          1
# 0  76.297096  86.421851
# 1  26.041973   5.265947
# 2  24.292204  37.074964
# 3   2.033896  19.136688
# 4  13.527561  25.136911

XML data:

Answer 3

Question:

This code creates a single track with a single segment.

How do you create a gpx file with multiple tracks and segments?

for example:

df = [ id, date, lat, long]

tracks = id

segments = date

points = (lat, long)

Thanks!
