Howto create multilayer maps from different ozi calibr maps

[gerdsuper]

Hello everybody,



is there a way to generate a multilayer map from several .png files wich are calibrated for ozi with ozi .map files?

I just converted them as standalone maps using oruxmapsdesktop. But would be great to have them combined into different layers.

Is there a tool wich can do that or is it not possible?



THX a lot,
