Being able to search for nearby items based on zip code

Hello everyone,

I am building a site which is a searchable directory of doctors.
Basically, doctors can register where their clinic is (address) and then
patients can search and find clinics.

Geocoding is the magic term you want to plug into Google. A quick search results in this http://geokit.rubyforge.org/ which may do what you want. There are many providers (free and commercial) of the postcode/zipcode lat/long details you will need as well.

Cheers,

Anthony

If what you are doing is OpenSource Nathan would you be so kind to
write a blog entry about it?

I came across http://zipcodesearch.rubyforge.org/ but geokit looks like it may be a more robust solution.
