Hi Colmn,

I don't use the location from logainm to match up to OSM objects.
Instead I use the hierachy. So if civil parish X is in barony Y in OSM
and logainm, and barony Y has a logainm:ref of 123, and logainm only
has one CP in barony Y with the name of "X", then we can match it up.

Also, at the moment, I've only match up counties, baronies, civil
parishes and townlands from logainm. I haven't let done any of the
other things like "population centres" or bridges.

[OSM-talk-ie] Oops, duplicate logain:refs added! (WAS: Re: Logainm data import #1 done!)

Hi all,

It turns out there was a little problem with the logainm import, which
Meenatuggart noticed. There are about ~120 logainm:ref's which are on
more than one OSM object. Duplicate logainm:ref's basically.

I've made a simple page on townlands.ie which shows the problems, so
that we can fix it up.

Please find the page here:

http://www.townlands.ie/progress/logainmqa/

I may add additional "QA" checks to that page when I can think of
additional ones.
