I'm just catching up as I was out all of yesterday (always seems to be loads of emails when I'm not keeping current) so this may have been covered already, so if so sorry. In Tendring most of the not:name tags are from after I went out surveying all the apostrophe discrepancies and the name I'm using in OSM is the name on the road sign. I also have looked this morning at the 4 new roads I have to go check in the district. Two seem to have added names to service roads, unfortunately at opposite ends of the district (Brightlingsea and Dovercourt). One is a road I marked as highway=road, but missed the FIXME=stub and hadn't noticed it since. It wasn't named in the last set of data, so this has helped me locate an actual road I'd missed. The fourth is a new road (recently built) that I had already surveyed: http://www.openstreetmap.org/edit?lat=51.843074&lon=1.073781&zoom=18 and the OS have the name wrong (they missed an L from MITCHELL), so I've tagged it not:name. Even bing only shows it as a building site so I was quite proud when I added it all last June in pre-bing days. >From the foundations I can see in bing though I seem to have estimated the location of buildings slightly out though. Having said that I have also added roads based on a combination of StreetView, OS Locator and Bing recently in the Bridgnorth district of Shropshire. I have added source:name=OS_OpenData_Locator where I have done so in much the same way as we used to add source=NPE to roads traced from the out of copyright OS maps (and I find realigning these a bit of a pain, too). I chose that area as I have some (admittedly a little outdated) knowledge of the area - I worked in Bridgnorth for a couple of years and we spent many weekends enjoying visiting areas of Shropshire when I used to live in Wolverhampton; I have had friends that lived in Bridgnorth and someone I was at school at was a councillor there. Looking at OSM Analysis I'm guessing I added about 359 such roads which increases coverage from about 29% to about 68%. While doing so I found a number of obvious typos in the OSM data on the few roads which were mapped, and there are roads I didn't touch because my recollection of the name agrees with OSM but I'm not sure enough to add a not:name tag without a survey. I have a feeling in one case the OSM name might be the local name everyone uses rather than the official name. I agree that we need to grow the community, but will having traced roads (whether NPE, Streetview, Bing or whatever) affect this greatly? I know it will upset existing active mappers in an area if it is done without consideration to their ongoing efforts, but in quiet areas of the country might the addition of roads change some people's perception from "OSM is rubbish in my area" to "Gosh, OSM has got my street on it - perhaps I can add my house/the path I take to cut to the shops/whatever"? Take for example Skobbler - in Colchester there are a few missing road reports which need a survey (too new to be on bing/os/fake reports), which is great (I've cleared away all rubbish reports to see the useful ones that remain). But what about someone trying to use Skobbler in an area where most of the roads are missing? Will they bother reporting lots of missing roads or get the impression OSM data is of no use? Too many questions, and judging by the many emails yesterday lots of different views.
