Thanks for providing that example @pisum, and there’s no need to apologize @tiwane. Yes, I was trying to consider whether the “union” of all three criteria covers all observations, or if there are some that won’t show on taxon maps no matter what boxes a user checks. I think @pisum’s observation definitely proves the latter scenario.
I agree that it’s better not to add too many checkbox options. My preference would be that iNat chooses complementary criteria so that checking all three boxes ensures that every observation for that taxon is shown. How about these three buckets?
- Verifiable Observations
- Observations w/o Media
- Other Casual Observations
The last one would be all non-verifiable observations that don’t meet the criteria for #2.
