Re: Geographical Location Distance Tool



Hi Nils,

The former would be fine for me as it is just to give a rough indication of
distance and does not have to be completely accurate. Is there an ability
to obtain postcodes and equivalent x-y co-ordinates and an algorithm to
calculate linear distances?

Thanks

If you would have a list of zip-codes + geographic location, then the only
thing you can do is calculate the linear distance between them. This is
definitely not the same as the distance over the road.

So if you want real distances (and estimation of time for travel), you'd
have to have a map database too, and algorithms to calculate the shortest
route, keeping in mind maximum speeds and such.
