What is a term to denote someone who is obsessed with or erudite in geography?
What is a good term to denote someone who is obsessed with, or erudite in, geography?
Solution 1:
Geographer.
Geographer on Wikipedia: A geographer is a scientist whose area of study is geography, the study of Earth's physical environment and human habitat.
I'd suggest that, while this doesn't exactly apply to obsessives, it certainly would apply to the erudite and those who are generally very interested in geography.
