I uploaded many observations, most composed of several photos, made at Sarykum Sand Hill in Kumtorkalinskiy District/Rayon, Dagestan, Russia. Each time the first photo got ‘Buynakskiy Rayon’ in the inferred location while all other photos ‘Kumtorkalinskiy District’. Each time the photos were just different shots made while I did not move, and project to the same correct point on the map. Buynakskiy District is nearby, and I know very well that borders are approximate here and administrative attribution may vary and be somewhat incorrect. But I am amaised by the strict regularity in this area: the first photo always wrong, others correct. Examples:
it doesn’t look like you’ve actually loaded these observations yet. what are the exact coordinates of those photos (both good and bad)?
my first thought is that even though they look like they’re the same point on the map, their coordinates might be ever so slightly different. however…
i’ve never looked deeply into this, but i suspect the automatic place descriptions are usually determined by the boundaries established by Google (via reverse geocoding), but it’s possible that in some cases, the automatic place descriptions come from iNat places.
i’ve previously noted behavior where some observations get a detailed place description (as if reverse geocoded), and others simply get a county-equivalent place description: https://forum.inaturalist.org/t/rename-loading-metadata/2826/7. i never understood exactly what was going on here, but i think it still happens, and it may be what you’re seeing in your case.
Since I could not illustrate the case with already uploaded observatoins, I made these examples without pressing ‘submit’ but sumbitted those photos in about half an hour. The coordinates varied in some 6 digit after the comma, as usual, and differently for different photo sets, nevertheless each time the first photo had B… District and others K… District. I suspect that outlines of both district were rather rough and just overlapped in that area. I noticed that the B has the Russian word ‘rayon’ (which means district) and the K has the English word ‘district’. It looks like these two belong to different series of places, as you supposed, and iNat has different priority irder of place search for the first (main) and subsequent photos. Of course, there is no big problem in this at all.
