Offline map is a map which can be used when device is not connected to internet, however it also works when device is connected to internet. Firstly you need to download them to your device. GPX Viewer PRO currently supports only offline map data which can be downloaded directly in GPX Viewer PRO, it does not support custom 3rd party offline map data as of yet. These offline map data are based on OpenStreetMap data. Basically when you download some offline map data, in reality you download raw vector, hillshade and contours data for this offline map. These data need to be styled in order to be shown on the map. GPX Viewer PRO supports several offline map styles as is shown in the screenshot below. Currently it does not contain style which is similar to default OpenStreetMap map style, but we are working on to add this style into GPX Viewer PRO.

Below you can preview offline map styles which are available in GPX Viewer PRO to use for showing offline map data.
