A command line tool that animates your exercise maps, inspired by an article by Andriy Yaremenko.

Features

• Supports FIT, TCX, GPX files. It can also traverse into ZIP files for easy ingestion of bulk activity exports.
• Outputs GIF, animated PNG, or a ZIP file containing each frame in JPEG format.
• Activities can be filtered by sport, date, distance, duration and geographic region.
• Configurable color scheme.

Example usage

> rainbow-roads \
    -sport running \
    -after 2020-08-01 \
    -min_duration 15m \
    -min_distance 3km \
    -bounded_by -37.8,144.9,5km \
    -output lockdown_project \
    path/to/my/activity/data

Some basic statistics are output to help validate the activities that were included and to aid in further refining filters.
