-The application ​offers two different ways of accessing ​maps offline in order to suit most users+The application ​is able to display a wide variety ​of maps. They are made of images, each level of details consisting of a different set of them. Using images allows ​to have a larger variety of maps, with a better quality, more details, and use little power consumption (and so battery).

 When a map is selected from the available maps list, the application will download, display and store on the device all displayed areas. Everything that has been displayed once remains stored and available for off-line use. When the same area is displayed again, the application will use the stored data instead of downloading it again (unless the stored data is too old and a new version can be downloaded). When a map is selected from the available maps list, the application will download, display and store on the device all displayed areas.

 +**How often are updated the maps?**\\
 +The application only display maps available from various online sources. Map updates only depends on the map editor of the map you've selected. In general, the application will display the last available version. For example, if you display the Google Satellite images, you'll see the most recent images available on the Google Maps website, however, those image can still be relatively old depending on the area displayed.
 +
 +**Is is possible to display real-time aerial imagery?​**\\
 +No, the application allows you to display the latest version of major online maps, including Google, Bing, Esri imageries, but you cannot choose a different date, nor display more recent images than the respective website versions. The stored data is regularly updated by the application when newer versions are available online.

 **Is it possible to increase the download speed of maps?**\\ **Is it possible to increase the download speed of maps?**\\
 Each map uses its own map server and has a different download speed. Various factors can impact the download speed, including your physical location and the current server charge. We try to keep the default map as fast as possible to download, but don't hesitate [[en:​help:​v2:​maps:​on-demand-change|to select another map]] that may be faster for you to access. If you need to download lot of map data, try to avoid rush hours to get a better speed. Each map uses its own map server and has a different download speed.

 +**When displaying an on-demand online map, I'm only getting the error message "​SSLHandshakeException"​**\\
 +It probably means you're using a quite old device (Android 4.4 or less) which is unfortunately not compatible anymore with the more recent security protocols requested by this map. This only solution is to use a device with Android 5.0 or more. If it's already the case, please contact us by email to report this map.
