Hi,

I want to try and setup a "search radius" feature on my site; so people can perform city/zip code radius searches.

I was talking to my programmer and we agreed that we would probably need a database that lists the country, city, zip code, and coordinates.

Does anyone know of a website where I can either download a database like this for free, or purchase it?

I'm mainly looking for UK, US, and Canada...or if there is a database that lists all countries it would be fine, but I guess that database would be extremely large!

Thank you,

olimits7

You can get it from Melissa Data. I got a US/CA Phone database with coordinates and city names for $395/year, updated quarterly. I think this is what you might be looking for, if you want to pay.

I'm not sure if there are open-source free versions...
Here are a few others I found searching google:

Geocoder
[cs.indiana.edu...] (FREE Database!)
Geonames
[census.gov...] (Maybe related, jgeodecoder Java app uses this data)
CSPan Geo-Coder-US (Perl Library to do the same with TIGER data, listed above)

A lot are US-specific. There may be others, here's something on the UK

Thanks for the links...

I also found a good US & Canada free download here: Populardata

However, I'm still looking for a UK database which lists the city, coordinates, zip code, etc...

Does anyone know if there is a site where I can download a UK database?

Thank you,

Sorry for the commercial links, forgot the charter. If you're interested in some of the commercial options I know about, PM me directly, so as to keep the forums appropriate. :-)
