Hi,

I am have a small issue with an overpass / relation issue, someone might be able to point me in the right direction...


I have a geojson file containing the borders of all the counties in the republic. I extracted from OSM a few years back, I think I used XAPI to extract and did some conversion/flattening but I'm not 100% sure of the process.

I now need all the counties in Ireland (the Island) and was trying to export these via Overpass Turbo, I thought I had it working but have hit a bit of an issue.

My query and export go fine as does the conversion from json to geojson (using osmtogeojson), but I am ending up with a geojson file with ~9k features, where I was expecting 32.

The overpass query returns 32 relations (as expected) and 9735 ways (which I presume make up the border), I know I am doing something wrong but I am not too sure if it is with my overpass query or my processing of the result set.

Any pointers would be great, I have included the query below, it can also be viewed at http://overpass-turbo.eu/s/9N3

Thanks in advance,

Keith
