I've drawn a cylindrical world map for a fictional planet. Exported it as png and scaled it, so one pixel corresponds to one km at the equator and from north to south pole.
I tried several cylindrical crs on it but it does never work out as I want and I can't find out why.
My goal: When I use the measure tool it should give me the following outputs:
- Horizontal length of equator (width of my png) = 38,211km
- Vertical distance from north to south pole (height of my png) = 19,105.5km
- When I measure the horizontal distance where the poles are (top and bottom rim of my png) it should show 0 km because of the cylindrical projection.
How can I georeference my png to get these results?
