[OSM-talk] postcode idea

I think most people have lists of addresses they have compiled, or we
could probably get databases of addresses off-copyright. I know I
personally have at least 100 addresses, possibly many more than 1000 if
I start searching. I have probably 3000 items of correspondence stacked
up and I won't burn them if I think we could use the data.
When I sell items on-line, people send me their address and postcode. I
suppose this could be used.
Anyone who is or has been in business probably has substantial address
If I can stick postcode pins in the OSM on-line map, I could probably
stick a further 50-200 pins from my memory and personal records.
Once we have a fairly complete open street map, with named segments and
localities, merging plain address data will give us a fairly accurate
postcode map. It will enable us to automatically attach postcodes to a
street. Once we put at which end number 1 is, or the way the street is
numbered (one side odd one side even or looped) we will have enough data
for a very accurate postcode map.
If we have a combination of postcode pins and collection of raw address
data, we would have enough data to extrapolate the street numbering
scheme and fill in the gaps.
If addresses without names don't violate data protection etc, maybe we
should start collecting raw addresses. Perhaps a form on a web page
where I could paste multiple addresses blank-line delimited. This way,
if an address comes in, I can cut & paste it into a text editor, then
paste it into an on-line form.
