GPX manipulation for humans

Python package for manipulating gpx files and easily convert gpx to other different formats.

• Free software: MIT license
• Documentation: https://gpx-converter.readthedocs.io.

When & Why

• You need to convert GPX to other formats
• You need to convert other formats like csv to GPX
• You want to interpolate the GPX coordinates
• High level of abstraction
• Stable API
• easy to use and to extend

Motivation

I decided to create this project because I had gpx data that I needed to manipulate. I searched for a python package for this but I did not find what I was looking for, therefore I created the gpx-converter package to make gpx files manipulation very easy. Furthermore, the package contains methods for applying interpolation on the gpx data. This feature was very helpful for me since I also needed to interpolate the gpx data and convert it to csv. Feel free to contribute or to give me feedback anytime :)

Features

• Convert gpx files to other formats such as csv, numpy arrays, dataframes, excel and json
• Convert csv files to gpx
• Apply interpolation on the gpx data

Installation

.. code-block:: console

$ pip install -U gpx-converter

Quick Usage

.. code-block:: python

from gpx_converter import Converter

Just read the gpx to dictionary

.. code-block:: python

dic = Converter(input_file='your_input.gpx').gpx_to_dictionary(latitude_key='latitude', longitude_key='longitude')
# now you have a dictionary and can access the longitudes and latitudes values from the keys
latitudes = dic['latitude']
longitudes = dic['longitude']

Convert GPX to other formats

• Convert from gpx to csv:

.. code-block:: python

Converter(input_file='your_input.gpx').gpx_to_csv(output_file='your_output.csv')

• Convert from gpx to excel sheets:

.. code-block:: python

Converter(input_file='your_input.gpx').gpx_to_excel(output_file='your_output.xlsx')

• Convert from gpx to json:

.. code-block:: python

Converter(input_file='your_input.gpx').gpx_to_json(output_file='your_output.json)

• Convert gpx file to dataframe:

.. code-block:: python

df = Converter(input_file='your_input.gpx').gpx_to_dataframe()

• Convert gpx file to numpy array:

.. code-block:: python

np_array = Converter(input_file='your_input.gpx').gpx_to_numpy_array()

Now convert other formats to GPX

• csv to gpx

.. code-block:: python

Converter(input_file='your_input.csv').csv_to_gpx(lats_colname='column_name_of_latitudes',
                                                 longs_colname='column_name_of_longitudes',
                                                 output_file='your_output.gpx')

• excel to gpx

.. code-block:: python

Converter(input_file='your_input.xlsx').excel_to_gpx(lats_colname='column_name_of_latitudes',
                                                 longs_colname='column_name_of_longitudes',
                                                 output_file='your_output.gpx')

• dataframe to gpx (notice that the method is static)

.. code-block:: python

Converter.dataframe_to_gpx(input_df=your_df,
                           lats_colname='column_name_of_latitudes',
                           longs_colname='column_name_of_longitudes',
                           output_file='your_output.gpx')

• json to gpx

.. code-block:: python

Converter(input_file='your_input.json').json_to_gpx(input_df=your_df,
                                                   lats_colname='column_name_of_latitudes',
                                                   longs_colname='column_name_of_longitudes',
                                                   output_file='your_output.gpx')

• Automate the conversion of multiple csv file to gpx:

.. code-block:: python

Converter.convert_multi_csv_to_gpx(dirpath='your_directory/')

• Apply spline interpolation on gpx file (you need to install scipy for this to work):

.. code-block:: python

interpolated_coordinates = Converter.spline_interpolation(cv=your_array_of_control_vertices)

Usage from terminal

Alternatively you can use the gpx_converter directly from terminal. You just need to pass the function, input file and output file as arguments.

• function: the conversion method you want to use. For example "gpx_to_csv"
• input file: path to your input file
• output file: path to your output file

.. code-block:: console

$ gpx_converter --function "gpx_to_csv" --input_file "home/your_input.gpx" --output_file "home/your_output.csv"

or maybe you prefer the short version

.. code-block:: console

$ gpx_converter -func "gpx_to_csv" -in "home/your_input.gpx" -out "home/your_output.csv"
