Hi Nick,
Here are a few tidbits to start you off from the SAS-L archives:

Subject: LAT/LONG COORDINATES--DISTANCE BETWEEN THEM
Hello,
I have a data set containing LATITUDE and LONGITUDE coordinates(degrees
minute seconds). I show an example of two records:
LATITUDE LONGITUDE
40 02 40 -76 24 45
42 21 12 0880536
Q1: In SAS, how can I compute the distance in miles (km, etc.) between
LATITUDE and LONGITUDE columns above? I would like to use an accurate
mathematical formula to compute the distance.
Q2: Same as in Q1 but we can use a less sophisticated mathematical
formula to compute the distance.
What I am after in this question is that I wish to find the distance
between high-schools and nearby prisons with sex-offenders, etc. If I
know the LAT/LONG of school and prison, can I find the distance beyween
them?
In Q1 I assume that the school and prison may or may NOT be close to
each other. By close I mean within 10 miles or so. Since I don't know
how close they are, I wish to use a more sophisticated mathematical
formula to compute a fairly accurate distance, as accurate as we can
anyway.
In Q2 I assume that the school and prison are close to each other so
that the pythagorean distance can be used, I assume.
Thanks all.
NICK
