Is there a way to filter out the same animal entered by multiple users from the same location, date and time? For example: 215059847, 215165421, 215598864, 225579604; and 233998846, 233805671, 233524094, 233384547. For some species, there are 10+ records for the same animal/date/time/location. It si…

Hi, welcome to the iNat forum! An observation represents an individual’s experience documenting an organism, so there are no violations on iNaturalist with there being multiple observations of the same organism by different people. Because of that, there won’t be efforts to tell people not to make o…

[image] oreganus: It significantly skews abundance data when a group of people photograph the same animal at the same time, and all of them enter it into the database. As a note, iNat data doesn’t equate to and shouldn’t be translated as abundance data. There is no standardized effort metric …

[image] oreganus: It significantly skews abundance data None of us would claim that our observations represent abundance data. No obs (yet) does not mean not seen, or not there.

[image] oreganus: same animal entered by multiple users from the same location, date and time When this happens, the observers are most likely students who have been instructed to post to a class project, and who proceed to do so as a group on their school campus or perhaps at a local park. …

In my experience iNat helps you to get an overview for abundances for species that are rather frequently observed. And this has been very helpful to me in the past. But anyone trying to get reliable data for academic research will have to do a lot of work to achieve a significant quality.
