[Qgis-user] QGIS question

[Siki Zoltan]

Dear Gergő,

you can create custom CRS, use Settings -> Custom CRS from the menu.
You must know the definition of the projection in Proj.4 format.
See: 
https://www.qgis.org/en/docs/user_manual/working_with_projections/working_with_projections.html#sec-custom-projections
http://gis.stackexchange.com/questions/20566/how-to-define-new-custom-projections-in-qgis

If you mean planet Mars, then you must define a datum too. AFAIK QGIS 
database contains datums for the Earth only.

Regards,
Zoltan
