I would like to offer a geographic search on my website. That is "Find all things within X miles of zip code Y". Is there any open source or freely usable code to do this? If not, what commercial packages are out there for use on a web server (ASP.NET and IIS). Thank you!
How do websites compute distances (eg: find x within y miles of z)? Can you recommend software to do this?
Interesting question. It got me looking... I figured it used zip codes. Based on that I found this link: http://sourceforge.net/projects/zipdy.

As a postscript, it took only a couple of hours to convert zipdy to an ASP.NET web service written in C# and using MySQL. It was written for Linux in C for PostgresSQL.
Thank you AGAIN for the pointer. Report It

Go to "Ask Yahoo!". Or go to "Contact Us" or "Feedback". The people here seem very nice and helpful.
