[Talk-GB] The last 2%

Hi, Thanks for the replies,
I think I may have found out something
If I look at Pentland Gardens
http://oscompare.raggedred.net/?zoom=18&lat=55.91088&lon=-3.21477&layers=B0TF
I have placed a tag
not = Pentlands Gardens
instead of not:name= Pentlands Gardens
so this would make the analysis out considerably in my area. Now that I have this information then this should make a difference. I was obviously just following the wrong tagging scheme. I think there may be others that are doing the same as me so it may be good to let people know.
 With the ITO world OS Locator from the above link. If the squares showing the names are all solid lines.
I suggest that if they don't match and contain the not:name tag then placing a dashed line around them would indicate that I have a conflict that has been looked at.
Eventually what I will be left with are the roads where there is dispute over the name and not mixed together with roads that have not been surveyed and named.
thanks for you help
Cheers
Bob

Hi,

I am the developer who works on a number of products including OSM Analysis for ITO.

I am slightly confused about making the OS Locator box a dashed box if the not:name tag is present. When we do the processing if any street is found with the not:name tag matching an OS Locator street then these should not be flagged in the stats nor should they be drawn on the map. Are you saying that this is not the case and they are still appearing? If this is true then possibly there is a bug that I may want to address (we are usually a day behind the updated planet file so possibly its something to do with that?)


With regard to getting the figures down (in slight fear of being flamed as I am a very novice mapper) - with apostrophes, if the road sign has an apostrophe then I would say the apostrophe should be in OSM and if it is not then it is correct to flag it as a difference. However if the road sign does not have an apostrophe and OS Locator does then probably the road should have a not:name tag added with the apostrophe version of the name. This would remove any apostrophe issues. With regard to rural roads - if they have no road signs is it not better to use the OS Locator name rather than have no name at all as I think in general OS Locator has been proved to be pretty accurate? (apologies if in my ignorance I do not know that there is a good reason not to do this).

Congratulations, only 87 roads (<2%) is an 
impressive achievement.
 
I'm struggling to reduce figures much on the Isle of Wight due to many road 
signs not have apostrophes (whilst OS Locator includes apostrophes), and 
many rural roads having no road signs at all

      Hi,
        

        I have been using the OS_locator and musical chairs tools to focus 
        on the areas of Edinburgh that needed checking. I have also been using 
        the ITO analysis tool to check my progress.
        

        http://www.itoworld.com/product/data/osm_analysis/
        

        All of these have been very useful and much appreciated
        

        I use the boundaries shown in
        

        http://www.ordnancesurvey.co.uk/oswebsite/opendata/viewer/
        

        to focus my attention in one area
        

        In Edinburgh we have about 87 roads to go. I know that there are 
        many of these roads that conflict with the OS_Opendata names. This is 
        due mainly to spelling, roads with two names, new builds that need 
        survey etc. 
        

        I believe that there are more roads marked as not in OSM than are 
        marked in OS_Locator about 20 in the case of Edinburgh. I thought this 
        may have been service roads or unnamed roads further outside the city, I 
        found many of these but these do not seem to affect the scores of the 
        OSM_analysis. I am not sure if this is me just missing roads or OS 
         database data quirks
        

        Are there any hints or insights that people can give me to help me 
        find the last few roads.
        

        Once I have brought the number down I can then check with the 
        council and have "Street sign, Official Council name, and OS_OpendData 
        name" and then be able to report to OS.
        

        On a slightly different note is there any plans to have the 
        OS_locator squares marked as a dashed line if there is a tag present 
        that says not:name. This would be useful for me to show that a street 
        has already been checked
        

        Many thanks
        

        Bob
