So first off i'd like to say hello. I have browsed your forums on several occasions but finally decided to join. I am currently working on a big project. I would like to share a bit of it for you and perhaps start a discussion.

I apologize if I sound a bit foolish at any point as I know many of you have years more experience than I do in this.
I'll start with a few premises so that we can get a few things out of the way.
1) I use a mac and therefore I have several limitations when it comes to available programs (no ability to use CC3+ is one example)
2) Whenever possible I go for free options, as this is a hobby and my funds are limited
3) I'm here to learn

So my question, or perhaps more accurately my problem, is that there seems to be no program anywhere that will allow a person to take a drawing (like an Eckert IV projection) and wrap it onto a globe.

When most people think of mapping a fantasy world they tend to draw on a flat surface (or program) using a projection that they are familiar or comfortable with. In my case I used an Eckert IV projection printout and simply sketched the basic landmass shapes. I scanned the image and used google sketchup (taking great pains and hundreds of hours) to make a cad version of my map. From there I was able to manipulated it in many ways, make rough topography lines and figure out mountain ranges, etc. I was also able to make political maps and climate maps. However, when it comes to functionality, in particular measuring distances between points and scaling maps down to specific regions, a cad program is not very optimal.

As the mapping part is essential to my book, and I already have a lot invested into the shapes and locations of my landmasses, can anyone give me some pointers?

I would like to include picture references, but apparently I am unable to (either because I am too new, or for some other reason) so I have included a link instead. Hopefully they work.
