How to work out the distance between two full UK postcodes?

Question

I have all the UK address postcodes in a database file (not the street names though). I want to work out the distance between two postcodes. I also have all long' and lat' data. Using this, I know how to work out the distance as the crow flies, but i want to work it out so it is more accurate. Does anyone know how to do it? any programming language is fine. Would really appreciate the help. Thankyou!! I will be posting all UK postcode addresses soon for everyone to have.

Not sure EXACTLY what you're trying to do but I use this:  http://www.multimap.com/directions/

Answer 4

Download google earth, its free, you can put 2 postcodes in, it will tell you the distance and how long it takes to get there, also directions

Answer 5

Don't know if you mean this, but can't you just put in the Long. and Lat. coordiantes into this website and work it out?
