I am trying to divide the world space to geographic sub-space from "general" to "specific" locations and without using latitude and longitude information. That is, I am trying to think about the world in someway like the following:
The most "general sub-space" > ... > The most "specific sub-space"
Continent > State > Region > ... > City > Town > Address
What is (are) the most used "division approach(es)"?
What is (are) the most efficient "division approach(es)"?
