I love mapping! I first stumbled over cartography in fifth grade (we had to do a properly measured map of our school grounds) and always came back to it. Every fantasy world I imagined came with a map. It’s a great way of keeping track where your characters end up after you chased them over some hills and through a swamp. And if you can get them artfully done, it’s a beautiful and useful extra for your readers. But here comes the BUT. While beautifully drawn, many fantasy maps are put together a bit thoughtless. There is a big amount of transformation happening when you try to display a three-dimensional world in two dimensions. Mistakes happen. That’s where I come into play. I’ve got a Master in Geological Sciences with a focus on neotectonics and geomorphology. Geomorphology is the science of landscape formation: i.e. how do mountains form, what determines the run of a river or how do coastlines change. You wouldn’t publish your novel without running it by a professional editor. So, why not treat your map the same way?
