What is missing, is AL8 - used for "Districts" in the UK. Counties used to exist in NI but they are now defunct as administrative entities. The boundaries seem to be (still) there in OSM, but with boundary=historic admin_level=6. I am not sure where the existing AL10 data came from, and what these boundaries are used for in practise.
The problem may be connected with a lack of open data for government information in NI. They (including OSNI, Ordnance Survey Northern Ireland) seem to be lagging behind the rest of the UK on that front. Interestingly, the UK AL4 boundaries (for the nations of the UK: England, Wales, Scotland and Northern Ireland) demarcate the territorial waters, and not the limits of normal administrative jurisdiction. //colin On 2016-01-26 18:19, Walter Nordmann wrote: > Hi, > > any reason why there are only admin boundaries with admin_level=10 in > Northern Ireland? > > No counties (AL6), no cities (AL8), no Suburbs(AL9) - nothing > > regards > walter/germany > > _______________________________________________ > Talk-GB mailing list > Talk-GB@openstreetmap.org > https://lists.openstreetmap.org/listinfo/talk-gb
