If you want the default spawning portal (the one from which you come into the map from Cape of Distant Worlds) to be within the map, then simply do this:
1.) Place a random object (preferably a small one, perhaps a plant?) where you wish the arrival portal to be.
2.) Hopefully, you've seen the small rectangular box below the map-creation options? Write down the Yaw, only.
3.) Moving on to the X, Y, and Z. Go to the object controls tab and write down the coordinates from there.
Once you have done this, go to the map tab and where it says "Has Portal:." Hopefully the box is already checked, if not, do so. Below it says "Destination Portal:" followed by the X, Y, Z coordinated plus a Arrival Yaw. Simply type in the coordinates you wrote down from before in the right boxes. The X, Y, and Z ones should fit, but the Yaw may not.
By doing this, it will not guarantee an accurate placement, but it will be better than spawning in the sky or off that map itself.
I hope I cleared the air a tad, if not, then I tried.
