Please help free the postcodes!
Does anyone here own a significant database of businesses, such as a business directory, which was created by users?
If so, if you could somehow give me access to your addresses (no business name or house number, just street name to postal code), I'll import this data into OpenStreetMap.org by matching the road names and tagging them with the correct postal code, then use the waypoint data to get the average GPS locations of the postal codes too, possibly even importing that back into Free The Postcode! (if they accept the CC license)
Your business will be cited as a source in OpenStreetMap's database, if that provides some incentive. Even if it's only a small database, it could be used as a proof of concept for a free import process.
If we all work together, we can free those postcodes. If you think you can help then please get in touch, you can contact me gaz at bitplane dot net.
