Perhaps more importantly it helps us build a useful working relationship with OS where we demonstrate that we have something to give, as well as take.

Many of the discrepancies around here need a close look on the ground, but in many cases the names ARE there and it is just a matter of getting the compare process to mae the connection.

Is it possible to analyse how much of that is independently surveyed and how much is just copied from OS? (I know that some mappers have not added source tags when copying from OS, and going through changeset comments is probably too hard, but it would give a rough idea.)

Quite right to. I almost did a post about Norfolk this evening, fantastic recent progress and the thought that it might make a good location for a summer mapping party and as a focus for various sit-at-home mappers as well. We are pleased to have Norfolk CC as a customer for whom we are producing public transport publicity information and I think we could persuade them to use OSM if it was of a consistently high standard across the county. We have been doing some armchair work (or actually office-chair work) in Norfolk ourselves over the past month and I also made a presentation on OSM at a recent ReWireed Norfolk event which was well received. If anyone did fancy organising a mapping party at some suitable location in Norfolk during the summer then ITO would be happy to supply drinks, pizzas etc to keep people's energy levels up!

I'd like to make a special mention for North Norfolk which was in the bottom 10 on the ITO table just a few months ago, and is now at 99.51% (and now I think 100% since I've added the names of five service roads in an RAF base).

They have definitely received a file of 3,500 not:name entries and there are people within the OS keen to develop relationships with the OSM community and use the data. However... it is a very large and long established organisation which doesn't seem to move that fast! What I do know is that it will be getting harder and harder for them to not engage and that the government is very supportive of what we are doing.

I have also been very impressed with the initial results from the visual comparison of OSM and OS Vector map district as well. We seem to have an much to help the OS improve their data as the other way round! We also have railway and electricity comparison layers in preparation which will also show OSM in an even better light compared to the OS (the electricity data in VDM is very poor indeed and the railway data isn't that good either - both are much worse than the OS roads data). What I am less happy about is the reliability of ITO's OSM services over the past week. True, we have added lots of stuff to ITO Map but in the process we left OSM Analysis statistics frozen for about week due to a stupid oversight and when we did a major code update to ITO Map yesterday to allow us to show other datasets such as Vector Map District which seems to have destroyed its performance. We will be spending some time on ITO Map this evening and see what we can sort it out and may need to roll the code back one version. If so then we will loose VMD roads layers for a few days.

[Talk-GB] UK "road name" coverage now over 80%
I just noticed that todays http://www.itoworld.com/product/data/osm_analysis/main ITO Analysis Summary shows we are now over 80% for "road name completion" (i.e. OSM road names compared to the OS Locator data). I think all UK contributors should buy themselves a pint for that. Top effort. We also now have 115 areas over 95% and 263 over 75% - this can only be a good thing for building confidence in the reliability of the map, particularly amongst users that are using the map data in car sat navs etc. The only black spot is that there are still 23 areas that are less than 50% road name complete, with the worst offender now being Easington with just 37.25% It's be great to get everywhere over 50% as ultimately we'll always be judged by our worst coverage. -- View this message in context: http://gis.638310.n2.nabble.com/UK-road-name-coverage-now-over-80-tp6529750p6529750.html Sent from the Great Britain mailing list archive at Nabble.com. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
