What's a GPX file?

GPX is a file format. The file format exported by GPS track information is GPX, which is a relatively common file for recording GPS tracks. When we go alone to unfamiliar scenic areas of mountains and rivers, explore outdoors or hike, the common navigation method is mobile map navigation. Everyone should be familiar with mobile maps and navigation, but there are often many changes in practice. For example, original roads will be blocked if they are under repair. Some footpaths won't be shown on the maps, either. For some cross-country routes, it is often safer and easier to use other people's tracks.
