import location ( Country and City )

Hello,

I have addes 2 Taxonomy on my web site:
1: Country
2: City

When the visitor select one countr ( first taxonomy ) then he cat select one city from the selected country.
Please let me know if it’s any way to import all this taxonomy ?
I just insert by hand 200 location.. but i need to insert more.

Any ideea if that it’s posible?
