Is there any research direction which is closely related with map reading?

I like maps very much, any common maps, geographic, historic, statistic, etc., or I would say reading maps is my favorite hobby. I can sit at table and read maps for several hours without any stop.

I was studying courses about computer in university, for example, data mining, computer system and computer networks. I am planning to pursue a PhD degree in the future. It would be great if I can convert or leverage the my map hobby as my career.

So my question is, considering my background (about data and computer networks), Is there any research direction which is closely related with map reading? If difficult to find such position in academia, is there any jobs in industry can greatly fulfill my idea?
