<div>I've drawn quite a few in my home town Ipswich, mainly in the south east (Gainsborough) and north west (Castle Hill) areas. Those were quite a lot of buildings only over a few months.

However... if you click on one you can "suggest an edit". It will be really interesting to see what happens over the coming months. Will Google end up with more active contributors than OSM? I can certainly see a lot of people editing little bits here and there.<br></div><div><br></div><div>It's for that reason why I think it would be interesting to look at our approach in OSM. I note that Frederik shared some thoughts on the AI buildings. Some of this can be fixed (e.g. I can see the land registry open data polygons being used to help split a terrace building into its relevant parts). Other parts are harder but worthy of more discussion - let's be honest here; we have less than 10% of addresses mapped despite this being a really useful piece of data for many users.<br></div><div><br></div><div>My view here is that with building outlines it becomes easier to get people to contribute to OSM in little ways, adding their housenumber and that of a few neighbouring buildings. With a simple editing tool and some good outreach to the media, we could get a good chunk of addresses mapped and introduce loads of people to OSM.<br></div><div><br></div><div>Is it worth OSM UK putting an "Open Letter" out to see what ideas we can get from both the wider community and those big companies? We can always say "no" if we are not confident of the process, but if we don't ask, we may never know what the full options are.<br></div><div><br></div><div>Best regards,<br></div><div><div><div dir="ltr"><div dir="ltr"><div><div dir="ltr"><span style="color:rgb(0,0,255)"><b>Rob</b></span><br></div></div></div></div></div></div><div> <br></div></div></div></blockquote><div><br></div></div></blockquote></div></blockquote><div><br></div> </div>
