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) http://spatialnews.geocomm.com/newsletter/2000/jan/cenzuszipcodes.zip Enjoy! - Kevin ----- Original Message ----- From: "Arkady" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, February 28, 2003 2:02 PM Subject: [PHP] Distance Calculator Hey guys, Can anyone here point me to a resource (not geozip) that can be used to calculate the distance between two zip codes?
