Offline map in a region

Is there any way to term the offline map of a region with this component?

Hi,


Unfortunately it's currently not supported to use offline maps.
However this is a good suggestion and we'll consider adding this feature in a future version.

It will be excellent, because it will save mobile Internet

If offline maps were possible, we could then develop an app for surveying in remote areas where there is no signal. A prerequisite would be that you can download/preload maps for the area of interest before visiting. 

I'm also very interested on offline mapping.
