[OSM-dev] Postcode to LonLat tool

[Richard Ive]

Hey Community,

I'm not sure this is the right section, but I'm going to assume it is so i'm just going to let all the development people here know about a tool I've been creating. It's a UK postcode geocoder.

I've created this using NodeJS. I set myself a goal of learning NodeJS, then deploying the project completely free of charge. Some how I've achieved it which I'm quite proud of seeing as the postcode database is about 1.7 million records and 400mb on disk. I do have the great guys at http://nodester.com to thank for the free NodeJS hosting, and the guys at http://dotcloud.com for their mongodb free hosting too.

It's still work in progress, I also know there are tools out there that do the same thing. However, feel free to try it, criticise it or just make any general suggestions :) In the future I want to add features such as locating other postcodes within an X radius of a searched postcode. I'll also make a distance calculator between two postcodes.

Enjoy!

Rich

p.s sorry if i'm in the wrong list.

Goodness, I got so excited I didn't mention how to use it!

http://postcode.nodester.com/ is the test page. (There's an input box bottom right).

If you want raw JSON use:

http://postcode.nodester.com/postcode/[postcode]

Cheers,

Rich

Those tools are really nice. There's not much to say since they seem
to just work :)

Also I guess that I should remind people of the Postcode Finder I
wrote a while back at
http://milliams.dev.openstreetmap.org/postcodefinder/. I haven't
updated the OSM data in a while (I will do soon) but it's able to
search via codepoint too.
