I have been using mappoint to manage my delivery vans for quite a while. However, I want to have a process before using mappoint which can tell whether the customer is in the delivery area or not. I want to do this on the web using longitude and latitude. I know my depot postition and so just need the customers position. I am based in the UK and the UK postcode data is very hard to come by.
Can mapoint export the longitude and latitude for postcodes? Or can someone tell me where to find this information?
p.s. I don't have a large amount to spend on databases at the moment to a cheap option would be appreciated.
