Filter posts by distance from a specified location.
This plugin implements simplistic functionality to WordPress posts by enabling archives to be sorted via distances from a specified location when certain URL parameters are detected. You are able to show how far the post’s distance is, and restrict results by a certain radius.
Supports various units of measurement and is customisable too.
Examples of use could be a job search or a store locator.

Have you ever wanted the functionality to allow your visitors to search for their nearest… shop, drop in centre, you name it?
This plug-in meets that need. You can create as many entries as you want, associate them with latitude and longitude using the Google Map API and allow your vistors to search for their nearest item by entering their own postal code.
This plug-in has been well tested with UK postcodes and also tested with US zipcodes and AUS postal codes among others. All feedback welcome.
