Lately, I’ve been thinking about the idea of creating a web app for storing and visualizing my cycle rides.

In this blog post, I would like to present my findings on how to store and visualize GPX tracks using Elixir/Phoenix, PostgreSQL and a little bit of JavaScript. The plan is to parse the GPX file and extract track data. Save it in PostgreSQL as a geometry type, which comes with PostGIS. Finally, visualize track using an interactive web map.
