it will contain a lot of postcode information from the original OpenStreetMap database, in adapted/translated form. </blockquote><div><br></div><div><div>This doesn't seem correct to me. In the final set, each point will only tell you yes/no whether it was in a particular postcode.

To create an accurate postcode polygon from point features you will need a lot of them, so probably already a handful of them would be considered substantial.<br></blockquote><div><br></div><div> This logic seems backwards. Since it would require a lot of point features in order to recreate the polygon (and thus something that looks similar to the original OSM database), it should require a *lot* of points to be considered substantial. <br></div></div></div>
