    Default Best projection for an equatorial continent map?

    I'm mapping an equatorial continent on my fantasy world that's roughly the shape and position of North Africa, extending to about 35 degrees south. I have it in equidistant which is fine, but I wonder what projection would be best to show equal distance? Any suggestions?

    Also any recommendations for what software to use to make projections?

    Hello Robulous

    I don't know much about map projections... I expect you have already found it anyway, but just in case you hadn't I found a list of them in a comparison table here:

    Mercator is a standard used in navigation for non polar areas

    http://www.geo.hunter.cuny.edu/~joch...projection.htm may offer some help (it was the first hit from a googly search for "choosing a map projection" (no quotes) ).

    Mercator doesn't maintain distances, it maintains lines of bearing. ie You can draw a straight line on the map and just stick to that compass bearing and you'll follow that line.

    Mercator and equirectangular are both cylindrical projections so have similar problems, I'm more looking for some kind of azimuthal projection. I'll have a play around.

    I was really hoping someone could recommend some projection software? I had a tool on my old PC which was very useful, but can't remember what it was called!

    Other than the Nasa Map Projector, I know of none. And that can only project from equirectangular and only whole globes.
