Eh well I've never built a distance calculator but I have used a Census data
file for various other things. The text file is comma delimited. The
schema is as follows..
Field 1 - State Fips Code
Field 2 - 5-digit Zipcode
Field 3 - State Abbreviation
Field 4 - Zipcode Name
Field 5 - Longitude in Decimal Degrees (West is assumed, no minus sign)
Field 6 - Latitude in Decimal Degrees (North is assumed, no plus sign)
Field 7 - 1990 Population (100%)
Field 8 - Allocation Factor (decimal portion of state within zipcode)

Hey guys,
Can anyone here point me to a resource (not geozip) that can be used to
calculate the distance between two zip codes?
Thank you!
