Marble is an Open Source alternative to Apple Maps / Google Earth:
Versatile, yet easy to use. Use Marble similar to a desktop globe; pan around and measure distances. At 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.
