Hi,
The Ordnance Survey OpenData released today contains a dataset called
Code-Point Open giving the coordinates of about 1.5 million postcodes.
I've added a layer onto the postcode area map to show this data in the
same way it's been showing NPE, OSM and FreeThePostcode data for some
time.
Go see it here:

There's still a few bugs to be worked out:
- only 25% of the original dataset is actually used (generation
process uses too much RAM on my 32bit machine to do the whole thing)
- not yet clipped to coastline
- sub-codes ie: "SW18 1" only show where the prefix is 3 chars
So nothing too serious :-)
Dave
