I just used mapquest.com to get any zip codes I would like to calculate the
long/lat for. You can get all that info there. Also below is your mystical
formula ;)
<CFSET City1="Los Angeles">
<CFSET City2="New York City">
<CFSET State1="California">
<CFSET State2="New York">
<CFSET Latitude1="34.0522">
<CFSET Latitude2="40.7142">
<CFSET Longitude1="-118.2428">
<CFSET Longitude2="-74.0064">
<CFSET Temp = sin(Latitude1) * sin(Latitude2 * pi()/180) +
cos(Latitude1) * cos(Latitude2 * pi()/180) *
cos(Longitude2 * pi()/180 - Longitude1)>
<CFIF temp IS 1>
<CFSet Mileage = 0>
<CFElse>
<CFSET Mileage = 3963.0 * (ATN(-Temp / SQR(-Temp * Temp + 1))
+ 1.570796326794895)>
<CFSet Mileage = Round(Mileage * 100) / 100>
</CFIF>
<CFOUTPUT>
<b>Temp value:</b> #Temp#<br />
It is <b>#Mileage# miles</b> from <b>#City1#, #State1#</b> to <b>#City2#,
#State2#</b><br />
</CFOUTPUT>

Subject: Semi-OT - Zip code dbs/dist. formulas?
Hey gang,
I'm wondering if anyone has, or can point me at, a good (i.e. cheap or free)
source for zip code data, along with lat/long values for each, and the
mystical formula for calculating the distance between one lat/long and
another lat/long.
Thanks,
--Scott
