Historical maps a lot, but there are others. For example, the night lights of the planet or the temperature map.
Not all the maps are in the standard delivery, additional can be conveniently downloaded.
The KDE developers – as free people, which is absolutely not tied to his home planet. With Marble you can fly over the surface of the moon, and as this and the one that existed only in the imagination of our ancestors.
Describe the program for very long, much easier to install and see for yourself.
In my opinion it works very fast, faster than google earth.
