The ground-vegetation map (switched off) shows the earth's surface; in brown the high mountains , in various greens the conifer forests, the tropical forests, the cultivated zones, in yellow and ochre the savannas, the steppes, the deserts and in white the polar areas or the glaciers.

Columbus doesn't just print their globes; they strive to create an incredibly deep, flawless shine. It all starts in their state-of-the-art 'clean printing room', where their craftsmen work just with superior acrylic sheets. Bringing in all kind of papers is strictly forbidden, because it would bring in fine paper dust particles which could later be attracted in the printing process. Printing up to 24 successive layers of colors, there's a curing process between each layer, along with an inspection and careful cleaning. Once the printing is complete, a high gloss clear coat layer is applied over the entire map, then it is sent back for inspection to our cartographic department.
