Alex Acks and Paul Weimer are teaching an online class on creating fantasy maps:
Join Alex Acks and Paul Weimer as they talk about fantasy maps in order to give you the tools you need to create and map your world. Topics include basic geologic principles, common mistakes, forms maps can take, how maps reflect world view, and how maps change over time.
Acks, you may recall, wrote pieces on Middle-earth’s problematic mountains and rivers, and fantasy maps in general; Weimer, for his part, wrote a defence of fantasy maps. The class costs $99 and takes place via Google Hangouts on 16 December.
