Frequently asked questions about Marble


I'd like to use the maps created with Marble for my website (or other purposes). Is this allowed?

Yes, as long as you give proper credits:

Marble usually uses several different sources of data to compile the map. We use only data which is "free" as in "Free Software" (which means that it's free as in "speech" not as in "beer"). Often we are using data from NASA or the CIA which is placed under the public domain according to the Freedom of Information Act (FOIA):

We also use data that is licensed under other free licenses which are in accordance with the Debian Free Software Guidelines (DFSG). This usually means that there are basically no "strings" attached to the data except for proper attribution. To find out about the actual licenses of the data you can have a look at the credits section for the data in Marble's About dialog.

In case you are using OpenStreetMap in Marble it's important that you add a line to your publication which gives credit to the OpenStreetMap Project.

I think I've found a bug in the map data. How do I report it?

This depends on which map you are using in Marble. If the bug is not in the OpenStreetMap map then you should report it to

If the bug occurs for OpenStreetMap then there are two options:

1.) Please consider getting involved with the OpenStreetMap Project. This has the advantage that you can fix the bug yourself:

2.) If you don't feel like fixing it yourself but if you just want to report it then OpenStreetBugs might be what you're looking for.

There is a bug in the clouds layer on 90°W 40°S. Can you do something about it??

The bug is in the data, so sorry at this point we cannot do anything about it. It doesn't always happen but it's quite often that the clouds don't "fit" on the lower eastern south.

Internet Connection

I can't get the proxy to work. Doesn't Marble support proxies?

Marble prepended the proxy domain with "http://" in earlier versions. This was done in error. Instead of "" please enter "" instead.
