GpxTrackPoster

Create a visually appealing poster from your GPX tracks - heavily inspired by https://www.madewithsisu.com/

Usage

First of all, you need directory with a bunch of GPX files (e.g. you can export all your tracks from Garmin Connect with the excellent tool garmin-connect-export).

You will need a little experience running things from the command line to use this script. That said, here are the usage details from the --help flag:

usage: create_poster.py [-h] [--gpx-dir DIR] [--output FILE]
                        [--language LANGUAGE] [--year YEAR] [--title TITLE]
                        [--athlete NAME] [--special FILE] [--type TYPE]
                        [--background-color COLOR] [--track-color COLOR]
                        [--track-color2 COLOR] [--text-color COLOR]
                        [--special-color COLOR] [--special-color2 COLOR]
                        [--units UNITS] [--clear-cache] [--verbose]
                        [--logfile FILE] [--heatmap-center LAT,LNG]
                        [--heatmap-radius RADIUS_KM] [--circular-rings]
                        [--circular-ring-color COLOR]

optional arguments:
  -h, --help            show this help message and exit
  --gpx-dir DIR         Directory containing GPX files (default: current
                        directory).
  --output FILE         Name of generated SVG image file (default:
                        "poster.svg").
  --language LANGUAGE   Language (default: english).
  --year YEAR           Filter tracks by year; "NUM", "NUM-NUM", "all"
                        (default: all years)
  --title TITLE         Title to display (default: "My Tracks").
  --athlete NAME        Athlete name to display (default: "John Doe").
  --special FILE        Mark track file from the GPX directory as special; use
                        multiple times to mark multiple tracks.
  --type TYPE           Type of poster to create (default: "grid", available:
                        "grid", "calendar", "heatmap", "circular").
  --background-color COLOR
                        Background color of poster (default: "#222222").
  --track-color COLOR   Color of tracks (default: "#4DD2FF").
  --track-color2 COLOR  Secondary color of tracks (default: none).
  --text-color COLOR    Color of text (default: "#FFFFFF").
  --special-color COLOR
                        Special track color (default: "#FFFF00").
  --special-color2 COLOR
                        Secondary color of special tracks (default: none).
  --units UNITS         Distance units; "metric", "imperial" (default:
                        "metric").
  --clear-cache         Clear the track cache.
  --verbose             Verbose logging.
  --logfile FILE

Heatmap Type Options:
  --heatmap-center LAT,LNG
                        Center of the heatmap (default: automatic).
  --heatmap-radius RADIUS_KM
                        Scale the heatmap such that at least a circle with
                        radius=RADIUS_KM is visible (default: automatic).

Circular Type Options:
  --circular-rings      Draw distance rings.
  --circular-ring-color COLOR
                        Color of distance rings.

Example:

create_poster.py --type grid --gpx-dir "my-tracks" --language "de" --year 2015 --title "Running" \
    --athlete "Florian Pigorsch" --special race1.gpx --special race2.gpx --special race3.gpx

creates a nice poster (poster.svg) of the GPX tracks in the directory my-tracks (see above).

Selection of Tracks

create_poster.py tries to load all GPX files in the specified directory (option --gpx-dir). To speed up subsequent executions of the script, successfully loaded GPX tracks are cached in an intermediate format that allows for fast loading; use the option --clear-cache to delete these files. Tracks without time stamps and tracks recorded in the wrong year (option --year) are discarded. Tracks shorter than 1km are discarded, too If multiple tracks have been recorded within one hour, they are merged to a single track.

Poster Types

Using the --type command line parameter, you can specify which type of poster to create:

Grid Poster (--type grid)

The Grid Poster layouts all tracks in a grid, starting with the earliest track in the upper left corner of the poster, continuing with the second earliest track to the left, and so on. Special tracks are drawn with the selected special color.

Example Grid Poster svg

Calendar Poster (--type calendar)

The Calendar Poster draws one square for each day, each row of squares corresponds to specific month. If a track was recorded of a day the corresponding square is colored with the track color or with the special color if the track is marked as special. A day's total track length in kilometers is printed below each square.

Example Calendar Poster svg

Circular Poster (--type circular)

The Circular Poster the year in a circle; each day corresponds to a circle segment. The length of each segment corresponds to the total track distance of that day.

Example Circular Poster svg

Heatmap Poster (--type heatmap)

The Heatmap Poster displays all tracks within one "map". The more often a location has been "visited" on a track, the more colorful the corresponding location is on the map. Special tracks are drawn with the special color.

Example Heatmap Poster svg

Setup

  1. Clone the repository: git clone https://github.com/flopp/GpxTrackPoster.git
  2. cd GpxTrackPoster
  3. Create virtualenv: virtualenv -p /usr/bin/python3 venv
  4. Activate virtualenv: source venv/bin/activate
  5. Install requirements: pip install -r requirements.txt
  6. Run ./create_poster.py (see above)
  7. Deactivate virtualenv: deactivate

Contributing

If you have found a bug or have a feature request, please create a new issue. I'm always happy improve the implementation!

Or even better: clone the repo, fix the bug/implement the feature yourself, and file a pull request. Contributions are always welcome!

Translation

The translation is based on GNUs 'gettext'. For the translation of the month names to work, the language must be installed.

Use locale -a to check if the language is installed.

Use locale-gen ru_RU.UTF-8 to install another language and update the locale update-locale.

Add new translation

Example: msginit --input=gpxposter.pot --locale=de_DE --output=locale/de_DE/LC_MESSAGES/gpxposter.po

Update a translation

E.g. use Poedit or Localise Online Editor to edit the "po" files. Afterwards compile that files.

Create compiled translation file

msgfmt gpxposter.po -o gpxposter.mo
