My current Project is to "map" a turntable in qgis. I know, very unlikely but that's what my teacher wants.
My teacher also wants me to measure something in this project (Very specific, isn't it?). And that's where the problem starts. Qgis wants me to define geographical coordinates or something like that. The problem is, that i don't have any coordinates because it's a picture of a turntable and not an actual map.
