Creating an actual map from top-perspective. How?

[Moody]

I think people are going to need more details than that if you want them to help you. Try giving us a description of what you have pictured in your mind for your map.

So.. I'm trying to make a isometric map. I understand the isometric and the axonometric projection. I'm not quite sure which informations are necesarry to write in here that people can help me. All I can say is that I'm a complete beginner concerning making maps. How do I even start?

I want to create a map with a wide see, a continent in south-east and a island in north-west. There is a village on the coast of the continent and a lighthouse on the island. A mountain chain divides the continent in two pieces from north to south. Well.. this is the map in my imagination. I would add much more details while I'm creating the map. But...yeah. How do I even start?

Is a map like this hand drawn then?
