Marble Futures:
Desktop
Versatile, yet easy to use. Use Marble similar to a desktop globe; pan around and measure distances. At a closer scale, it becomes a world atlas, while OpenStreetMap takes you to street level. Search for places of interest, view Wikipedia articles, create routes by drag and drop, and so much more.
Mobile
Turn your smartphone into a fully featured navigation device. It supports worldwide offline search and route planning, with free in-app map data downloads. Activate turn-by-turn navigation with voice guidance. There are rumors that a tablet and an Android app are in development.
Extensible
At its core, a software library powers the Marble applications, which are also integrated into numerous other projects, such as Digikam and the KDE workspaces. Developing with the Marble library requires only C++, Qt, and compliance with the LGPL 2.1 license. Additionally, you can extend Marble itself using plugins.
This lightweight, versatile map component is designed for seamless integration into Qt 4.x/C++ applications. The MarbleWidget offers a comprehensive solution for displaying maps and locations, including support for GPS tracking and importing KML/GPX files.
