Hi Colm, Thanks for your addition, every little helps! I agree with you that we must not assume that the mistake is always in the OSM entry. Often the entry in OSM is of greater value, even if it does not match any official names, for example, I have added the local name of a townland "Guesdian" I know this is the name everyone uses and it is the name on the townland marker-stone in the area. However the official name is "Geesadan" and there are alternative names such as "Gweeshadan" all for the same place. So we have to be very careful correcting names! I recommend to use local_name= and alt_name= tags where possible. We can check the version history of a townland relation (version #) and if the name does not change since it was first added, then I can assume that a local name was not added. The typos occurred when copying the name from the maps because they are hard to read. I think 4.3% error in names is actually impressively low.
The obvious way to identify a typo is to check if any of the names in the relation exactly match the original townlands map source. Those names should be present in some form, possible alt_name or something. http://maps.openstreetmap.ie/ and click mapwrapper GSGS3906 Cheers, Brian T On Wed, Feb 15, 2017 at 4:00 PM, Colm Moore <[email protected]> wrote: > Hi, > > > I corrected at least one - Kiltalown in Dublin- after checking with Rory: > http://www.openstreetmap.org/relation/4513764 > > > However, in dealing with 60,000+ names, we need to be careful and not > assume that all the mistakes are in the OSM data entry - it may be that > there are errors in other sources, e.g. "Little Island" in Cork shows up > some older Ordnance Survey maps as "LITTLEISLAND", which is somewhat > obviously incorrectly spaced: > > > http://maps.osi.ie/publicviewer/#V2,575522,571859,9,8 > > http://www.openstreetmap.org/relation/6514445 > > > Colm > > > ------------------------------------------------------------ > --------------------------------------------------- > Never doubt that a small group of thoughtful, committed citizens can > change the world.
