I am in the process of making a new world map and would like to use the Van Der Grinten projection. I would like to use the Van der Grinten projection and have it extend beyond the International Dateline on each side of the map so that I can achieve a more rectangular look.
I have noticed a number of other maps use this projection and appear continuous beyond the international dateline. Attached is an image of what I would like to achieve.
I currently have MapPublisher and Global Mapper software available.
Any suggestions on how to achieve this?
