Calculate distance between locations in SAS EG?

[JSJ]

Hi, I would like to calculate the distance between addresses in SAS EG. (In South Korea)

I am not sure if I have longitude and latitude or not.

I see there is a function Geodist if that is available.

Any ideas?

Thanks!

If you can settel with crude distance, there is another function ZIPCITYDISTANCE(); if you want it more precise, then:

Step 1. : Geocoding. Proc geocode. search it. there are many papers on this topic, and you will want street level geocoding.

Step 2: apply GEODIST on the coordinates you obtained from Step1.
