Hi David,

Again thanks for your reply but I think you are missing the part I'm having trouble with. I understand how your functions work. The problem is I can not create the image in the 117 GCTP format to begin with.

From my first post:
"The problem is that my lon/lat values contain a different number of values and Map_Proj_Forward() is complaining about this. Whay do they need to be the same? My overlay is a rectangular shape rather than a square why can this not be handled? "

The code in my first post is what I WANT to be able to do but can't. Maybe I should have tried to be more clear.
