En af Marbles kernefunktioner er understøttelse af forskellige kort (korttemaer i Marbles terminologi) og forskellige planeter. Hvert af disse kan ses i forskellige projektioner: Få planeten til at ligne en globus eller se det som et trykt kort ved at vælge en passende projektion.

Korttemaer indstilles i Marbles dialog Kortvisning. I skrivebordsversionen findes den et faneblad i panelet til venstre.

I den mobile version af Marble til Nokia N900 finder du dialogen Kortvisning via programmets hovedmenu.

The Map View dialog lets you choose a projection, the planet (celestial body) and a map theme. The rest of this tutorials explains these choices in detail.

Planet Choices

Marble supports about a dozen different planets. In the Map View dialog you can choose those planets where at least one map theme is installed for.

Earth. Plenty of different map themes are available.	Moon. We're aware it's not really a planet.
Mars	Venus

Projection Choices

The projection defines how the surface of the planet is presented on the screen. This can be a globe or some sort of a flat map.

	Spherical Projection	Flat Map Projection	Mercator Projection
Example
Common Usage	Distant view, measuring large distances	Distant view	Close view, navigation

Tip

Unsure which projection to choose? A rule of thumb is to use the Spherical projection at very large distances and the Mercator projection otherwise.

Map Theme Choices

Overview Maps

Map Theme	Preview	Description
Atlas		A classic topographic map. It uses vector lines to mark coastlines, country borders etc. and a height relief.
Plain Map		A simple version of the Atlas theme without topography.
Satellite View		Earth as seen from space with sun illumination. Includes a cloud layer with real-time data.
Natural Earth		Natural Earth portrays the world environment in an idealized manner with little human influence. Includes a cloud layer with real-time data.
Earth at Night		Earth as seen from space without sun illumination.

Street Maps

These maps are optimized for high zoom levels, showing many details on the street and city level. Some of them provide good country and even continent or space views, but that's not their primary area of use. Need to find a route? Do you like hiking or biking? Want to explore the neighborhood? Pick one of these maps.

Map Theme	Preview	Description
OpenStreetMap General purpose		The famous OpenStreetMap Mapnik layer. A general purpose map with useful information for the most common use cases. The map is identical to that shown on openstreetmap.org. Combine this map theme with the Mercator projection for optimal speed and a sharp map view.
Osmarender General purpose		The OpenStreetMap Osmarender layer. A general purpose map with useful information for the most common use cases. The map is identical to that selectable in the top-right toolbox on openstreetmap.org. Compared to the Mapnik layer (OpenStreetMap theme), this theme has more lively colors and presents some different data. The view from space looks better than that of Mapnik. On the other hand, Mapnik handles conflicting elements at the street level better. In Osmarender, icon sizes are less balanced and the z-order (stacking) is wrong for some elements. Labels overlap in densely packed areas. Combine this map theme with the Mercator projection for optimal speed and a sharp map view.
OpenCycleMap For bikers		OpenStreetMap data presented for bikers. The map is identical to that selectable in the top-right toolbox on openstreetmap.org. Combine this map theme with the Mercator projection for optimal speed and a sharp map view.
OSM Hike & Bike Map For hikers and bikers		A map theme optimized for hiking and biking, based on OpenStreetMap data. Includes a very nice hillshading layer that shows the terrain (activate it in the Legend). Combine this map theme with the Mercator projection for optimal speed and a sharp map view.

Restricted Maps

These map themes work fine in Marble from a technical point of view. The terms of service of the companies offering these maps, however, may prevent you from using it. If you want to use these map themes, you must install them manually. Make sure their terms of service allow you to use them within Marble.

Warning

To the best of our knowledge the usage of these restricted maps is forbidden in an application like Marble. We only want to demonstrate the technical feasibility here. Please don't add details on their installation in Marble to this Wiki. We don't want to promote the usage of maps which we think are not free.

Google Maps		Street maps from maps.google.com
Google Satellite		Satellite maps from maps.google.com
Mapquest		Street maps from mapquest.com
Virtual Earth		Satellite maps from virtualearth.net
