Yeah, in my day job I am all over the accurate spatial representation of field data and its associated uncertainty. In the iNaturalist context, though, I can only imagine 25M ad hoc accuracy polygons interacting with several 100K place polygons to determine project membership, etc. (While those numbers may not be there yet, they would be coming fast…) Would be wonderful if the infrastructure could handle that and still keep the rest of the site functioning responsively, but I’m guessing that would be very expensive.
