Creating a map, as in a parkour map, a map item, etc?
If item, it is a compass (which it is crafted with 4 iron surrounding a redstone dust) surrounded by paper.
If it is a parkour map you want to make, then first you need to create a world that you can work with. Once you see what you are building your map on, create blueprints on what is going where, where certain things need to be where (such as checkpoints), etc. If you have a storyline/theme to your map, then it may have to be top priority. Then you need to figure out what blocks you need to use. Then you do your redstone wiring. Have decoration go last though, because if you have no patience and work a few <unit of time>s at a time like me, making things pretty should go last.
If other, please specify.
I hope this helped!~
