zackrspv Posted March 16, 2009 Posted March 16, 2009 So, I was making a program to automatically show the distance between a client's START zip code, and that of the zip codes of our events. Since i made this script FIRST, to ensure that the math was working with the formulas i found online, I decided to make it a bit easier to read, and follow. Basically, it uses the (somewhat hacked version, hehe) Haversine formula to calculate the distance across a sphere from the given zip code's latitude and longitude positions. The data is provided by the US Census bureau, and the file is required to run the program NOTE: As it's math, and not pulling from a secondary site, no, it's not 100% accurate; but, hey, it gets you the information rather close to the actual distance.InstructionsDownload ZIP Code DATA: http://www.census.gov/tiger/tms/gazetteer/zcta5.zipDownload the following script, and put BOTH files in the SAME DIRECTORY and run What happens when script runs normally.What happens when Zip1 or Zip2 is bad.Enjoy!dst.au3 -_-------__--_-_-____---_-_--_-__-__-_ ^^€ñ†®øÞÿ ë×阮§ wï†høµ† ƒë@®, wï†høµ† †ïmë, @ñd wï†høµ† @ †ïmïdï†ÿ ƒø® !ïƒë. €×阮 ñø†, bµ† ïñ§†ë@d wï†hïñ, ñ@ÿ, †h®øµghøµ† †hë 맧ëñ§ë øƒ !ïƒë.
sias Posted March 16, 2009 Posted March 16, 2009 Excellent Program, and an interesting way of calculating distance. When I first read the topic I assumed you would just pull information from MapQuest or Google Maps; Using Latitude/Longitude is an original way of doing it.
