When searching for my village Crail on Nominatim I find that is it listed within the wrong county, East Lothian, when it should be Fife. Looking at the data on OSM there is no mention of East Lothian so what do I edit to make these changes?

I can also see from looking at the boundaries of the counties in Nominatim, Fife and East Lothian, it is clear there is rather glaring problem with the defined areas. Both of them should stop at the coastline and Fife seems almost engulf the county of Angus which also jumps into Fife.

I want to be able to help but I dont find the resources help new users enough.

The question has been closed for the following reason "Problem is now outdated. Nominatim has received quite a number of changes since the OP, and the behaviour described is not reproducible for this case. A more general phrasing of the question might still be useful." by SK53 22 Mar '11, 10:27


The counties are marked as nodes so Nominatim guesses the boarders with the help of is_in tags. Ideally the borders should be a multipolygon with boundary=administrative and admin_level=6

As I understand it you can use Ordinance Survey Opendata to make these multipolygons.

Thanks i will look into using the opendata for the multipolygon boundaries.

I do still have questions though.

From what I read I did think that nominatim was guessing boudaries based on is_in tags but surely if the is_in for Crail specifically mentions 'Fife, Scotland, UK', Nominatim should not then override that with a guess?

Furthermore I just searched for any is_in tags matching the wrong county name but came up empty, so where is Nominatum getting this erroneous data from?
