To get a "Postzon" Geographical Data address from our XML Web Service we do the following:
The distance between two postcodes can be returned. Simply call with Postcode and “Home postcode” provided in the parameters. Our service will then return the distance in km. So approximate charges could be applied to a customer based on the straight line distance.
This is the main use of PostZon data. Simply call with the target Postcode and the PostZon data service will return the Longitude and Latitude. Ideal for mapping and calculating distances.
To get the PostZon record by Longtitude/Latitude, (closest within 10Km) set postcode to the "Longtitude|Latitude" (separated by |). The Postcode found will be returned in pz_postcode.
To get the Longitude and Latitude of a Town, simply provide the Town name + “,SPACE“ + County in the postcode field. The Longitude and Latitude will then be returned. It is suggested that the town list is displayed using a AJAX search box.
