Thanks for the pointer to the styles. Any Idea how they determine which 
style to use for which geometry?
I did not see anything that looks like a way to select the one style or 
the other based on the geographic location.

Can you do the location check while rendering or would it be a 
preprocessing step during import? I did not see an additional "region" 
column so no idea how the selection was done.
