myOSM is an online and offline viewer for various map types such as OpenStreetMap, Cloudmade and OpenCycleMap. myOSM can also show your current location on the map.

There are some major advantages over the corresponding webpages:
* The maps can be accessed if not being connected to the internet.
* The various map types can be accessed within the same GUI.
* Bookmarks for easy access of often used locations
* Nearly fullscreen view of the maps.
* Maps can be saved for future usage.
* You can see your current location on the map.

The maps are stored locally on the harddrive and can also be used when being offline. You can download the maps at different zoom levels for the selected map region. Using this feature you can download a map e.g. before going on a trip.
