I am trying to produce a map like this completely in QGIS:
I can generate each half of the map in the main program by using
View->New Map View but I can't then find a way to make a map in the print composer refer to my 2nd map view (Map 1).
I thought maybe I could just change the map projection in the 2nd map on the composer but then it remains blank (may just need a method for setting the extent?).
I've also seen reference to using map themes and follow map theme but I don't seem to be able to create more than one map theme at a time so that doesn't seem to help either.
