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.
**Svarbios vietos** (techniškai vadinamos _waypoints_) atvaizduoja svarbią vietą, kad būtų galima atvaizduoti GPS įrenginyje arba skaitmeniniame žemėlapyje.
