Online maps are maps that can be used only when the device is connected to the internet. However, GPX Viewer supports caching of maps. When you show some locations on a map when your device is online it will cache those locations and when you turn your device offline and restart GPX Viewer and show those locations again they will be loaded from cache. But we don't recommend relying on this feature because the Android system can at any time decide to erase this cached data.

GPX Viewer is supporting adding your own online maps by adding server url addresses in XYZ format. Here you can find the tutorial how to add custom online map.

Below you can preview online maps which are available in GPX Viewer.
