+
+The <a href="https://www.topografix.com/gpx.asp" target="_blank">GPX file format</a> is an open standard for exchanging GPS data between applications and GPS devices.
+It essentially consists of a series of GPS points encoding one or multiple GPS traces, and, optionally, some points of interest.
+
+GPX files may also contain metadata, of which the **name** and **description** fields are the most useful for users.
+

+
+As mentioned above, a GPX file can contain multiple GPS traces.
+These are organized in a hierarchical structure, with tracks at the top level.
+
+- A **track** is made of a sequence of disconnected segments.
+  Furthermore, it can contain metadata such as a **name**, a **description**, and **appearance properties**.
+- A **segment** is a sequence of GPS points that form a continuous path.
+- A **GPS point** is a location with a latitude, a longitude, and optionally a timestamp and an altitude.
+  Some devices also store additional information such as heart rate, cadence, temperature, and power.
+
+In most cases, GPX files contain a single track with a single segment.
+However, the hierarchy described above allows for more advanced use cases, such as planning multi-day trips with several variants for each day.
+
+### <MapPin size="16" class="inline-block" style="margin-bottom: 2px" /> Points of interest
+
+**Points of interest** (technically called _waypoints_) represent locations of interest to show either on a GPS device or on a digital map.
+
+In addition to its coordinates, a point of interest can have a **name** and a **description**.
