"Marble is an easy to use geography application which comes included in the kdeedu package from KDE4.
"Marble Desktop Globe supports zooming in/out and has a pretty good database of cities, including all the major cities from each country all over the globe. The map itself is physical and includes only the borders between countries, with no other administrative limits present or names of landforms. When you click any city on the map, the exact coordinates of that city will be given, and the Wikipedia information will be displayed. Another wonderful feature is that Marble lets you print the currently shown map to PDF, PostScript or a printer, and, moreover, you will be able to export the currently shown map to PNG or JPG too, for online publishing or future references."
