I recently participated in a survey on Google+ to that effect and, thanks to the survey, I remembered my experience with KDE.
I like KDE not because I think it is superior than other DEs, but because I find its flexibility very convenient for my workflow. The first Linux distro that I tried was Kubuntu, but never installed it and became a Mandriva 2009 user. Needless to say, I was using KDE then.
Today, most of the distros I use have KDE, but I also use LXDE (with PicarOS) and Enlightenment (Elive).
Although I felt satisfied, I was missing Google Earth, which I recently had discovered and, those days, only ran on Windows.
KDE's option was Marble.
|This is the globe that greets you when you first open Marble.|
|Marble's OpenStreet map.|
However, I saw it as a very humble substitute for Google Earth, so, when Google Earth became available on Linux, I forgot about Marble... Until yesterday.
I did not know that one could load new maps for Marble and that made all the difference. With Marble, I can now visualize the conception people had of the world in 1492, before America made it to the map.
|Behaim globe, 1492. The oldest cartographic representation of the Earth known|
|Behaim globe, 1492. You can see sea monsters, but America is NOT there.|
|Cantino's map (1502). America was rather small back then.|
|Schagen's globe (1689). California was an island, the South Sea to the left of Central America!|
To download them , simply open Marble and press Ctrl+N (or go the the Menu, File, download Maps. You can get many more maps of the Earth...or the Moon... or of other planets and their satellites.
