Not directly OG but maybe someone could point in the right direction.
I want to be convert the first part of a UK post code eg SE22 to a Long/Lat
of a point within the area. I don't mind too much exactly which point.
I have had a look at geocoding and have got myself very confused (fairly
easy to do). I think the issue is partly copyright, and partly the fact
that geocoding is country specicic.
What I think I want is a table of top level post codes to places. Once I
have that I can do the conversion.
