Hello,

 

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?

Untested, but this is what I would try:

 

Use Global Mapper to cut a part of your data on either side of the IDL and move those +180 degrees and -180 degrees so you end up with a dataset that goes from say -190 to +190 degrees, then put that in MAPublisher and project it.
