+ | The application offers two different ways of accessing maps offline in order to suit most users: | ||
+ | * **On-demand maps** are maps retrieved on-demand from Internet and automatically stored on the device; | ||
+ | * **File-based maps** are maps covering a particular fixed area, pre-created and stored as single or multiples files on the device. | ||

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.

The application offers a wide range of maps, with some being pre-installed by default. You can remove them or install new maps from the **community maps list**, an extended set of maps mostly suggested by users. Note that the community maps list is regularly updated and can change without warning. | The application offers a wide range of maps, with some being pre-installed by default.

+ | \\ | ||
+ | File-based maps are pre-created maps copied on your device. Some key features are: | ||
+ | * They can be created at home, using a hi-speed Internet connection, which is usually faster than a mobile connection; | ||
+ | * They consist in a single file, which can be easily copied to or removed from the memory card. They can be easily exchanged over Internet; | ||
+ | * They have clearly defined bounds that makes clear which map is available at which location. | ||

- | [[en: | + | * The entire file must be on the device, even if only a small subset area is needed; |

+ | **How often are the maps updated? | ||
+ | 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 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: | Each map uses its own map server and has a different download speed.

+ | Each map has its own policy concerning how to display names. The default map uses the local language (i.e. localized names) so all users have familiar names displayed in their own languages. Other maps like Bing Maps only uses English names everywhere. You can also install an alternative version of Google Maps or Bing Maps displayed in various other languages, just [[en: | ||
+ | |||
+ | **Is there a size limit for the file-based map files? | ||
+ | Yes, on older devices. Android versions smaller than the 3.0 cannot manage files bigger than 2GB. On those versions you will get errors while displaying parts of the maps which are stored after this size limit. Starting with Android 3.0, you will be able to read bigger maps correctly. | ||
