A comprehensive Checklist for Sci-Fi writers working on Geography. Free worldbuilding resource from Obsidian Tavern.
Science fiction geography goes far beyond drawing continents and placing cities—it's about understanding how technology, alien environments, and future conditions reshape the fundamental relationship between civilization and landscape. Your world's geography should reflect and drive your story's core sci-fi concepts, whether that's terraforming, space habitats, or post-apocalyptic adaptation. Every geographic feature becomes an opportunity to explore how beings adapt to and transform their environment through advanced technology or alien biology.

Pro tips
✦Design your world's geography around your story's central technology—if faster-than-light travel exists, consider how this affects settlement patterns and resource distribution across planets
✦Use real exoplanet data as inspiration for alien worlds, then extrapolate how different atmospheric compositions, gravity levels, or radiation exposure would shape terrain and habitability
✦Consider the deep time implications: how would millennia of terraforming, climate engineering, or evolutionary pressure change your world's surface features?
✦Think in three dimensions and beyond—underground cities, floating habitats, pocket dimensions, and orbital structures all count as 'geography' in sci-fi
✦Research how extreme Earth environments (deep ocean, polar regions, high radiation zones) support life, then push those concepts further for alien worlds
Common mistakes to avoid
!Creating alien worlds that are just Earth biomes with different names—truly alien worlds should have fundamentally different environmental principles
!Ignoring the effects of different gravity, atmospheric pressure, or radiation on how landscapes form and civilizations develop
!Making terraforming seem instant and perfect—real planetary engineering would take centuries and leave visible evidence of the process
!Designing space habitats that ignore basic physics like artificial gravity generation, structural stress, or resource cycling
!Forgetting that advanced civilizations would engineer their geography—few sci-fi worlds should have purely 'natural' landscapes
!Creating FTL travel without considering how it completely changes settlement patterns, resource distribution, and territorial control
!Making all planets have Earth-like day/night cycles and seasons—different orbital mechanics create very different geographic patterns
Remember that in science fiction, geography is never just scenery—it's a character that embodies your world's technological capabilities, environmental challenges, and evolutionary pressures. Let your landscapes tell the story of how intelligence reshapes worlds and how worlds reshape intelligence in return.
